Recent Developments

We have recently experienced significant growth in our product sales. Our net sales for the years ended December 31, 2010 and 2011 were $3.2 million and $17.2 million, respectively. Our net sales for the six months ended June 30, 2011 and 2012 were $6.4 million and $32.0 million, respectively.

Conversion of Warrants into Common Stock

As a result of these warrant conversions and other extinguishments of derivative liabilities during the quarter ended September 30, 2012, our pro forma adjusted capitalization as of June 30, 2012 reflects a decrease in stockholders’ deficit from approximately $11,417,000 to approximately $6,815,000 and a reduction in our derivative liabilities as of June 30, 2012 from approximately $7,909,000 to approximately $25,000. All of these stock issuances, warrant conversions and extinguishments of derivative liabilities will be reflected in our financial statements as of and for the three and nine months ended September 30, 2012.

Summary of Statements of Operations 

RISK FACTORS

Any investment in our common stocksecurities involves a high degree of risk. Investors should carefully consider the risks described below and all of the information contained in this prospectus before deciding whether to purchase our common stock.securities. Our business, financial condition and results of operations could be materially adversely affected by these risks if any of them actually occur. This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks we face as described below and elsewhere in this prospectus.

Risks Related to Our Business and Industry

Our independent auditors have expressed substantial doubt about our ability to continue as a going concern, which may hinder our ability to obtain future financing.

As reflected in the accompanying unaudited interim consolidated financial statements, we incurred a net loss of approximately $9.9 million for the six months ended June 30, 2012, and we had a working capital deficit and stockholders’ deficit of approximately $12.7 million and $11.0 million respectively, at June 30, 2012. Also as reflected in the accompanying financial statements we incurred a net loss of approximately $23.3 million and used net cash in operations of approximately $5.8 million for the year ended December 31, 2011, and had a working capital deficit and stockholders’ deficit of approximately $13.7 million and $13.0 million respectively, at December 31, 2011. These factors raise substantial doubt about our ability to continue as a going concern.

In their report dated April 13, 2012, except for note 1 as to which the date is June 28, 2012, our independent auditors stated that our financial statements for the period ended December 31, 2011, were prepared assuming that we would continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should we be unable to continue as a going concern.

Our ability to continue operations is dependent on management’s plans to raise more capital, which include this offering, until such time that funds provided by operations are sufficient to fund working capital requirements.

In addition to the net proceeds from this offering, we could require additional funding to finance the growth of our future operations as well as to achieve our strategic objectives. There can be no assurance that future financing will be available in amounts or terms acceptable to us, if at all.

Our business and operations are experiencing rapid growth. If we fail to effectively manage our growth, our business and operating results could be harmed.

We have experienced and expect to continue to experience rapid growth in our operations, which has placed, and will continue to place, significant demands on our management, and our operational and financial infrastructure. If we do not effectively manage our growth, we may fail to attain operational efficiencies we are seeking, timely deliver products to our customers in sufficient volume or the quality of our products could suffer, which could negatively affect our operating results. To effectively manage this growth, we expect we will need to hire additional persons, particularly in sales and marketing, and we will need to continue to improve significantly our operational, financial and management controls and our reporting systems and procedures. These additional employees, systems enhancements and improvements will require significant capital expenditures and management resources. Failure to implement these proposed growth objectives would likely hurt our ability to manage our growth and our financial position.

As of April 10, 2013, management has taken over the shipping of most product, other than drop shipments, to our customers from our 152,000 square foot distribution center in Franklin, Tennessee. We have hired a warehouse manager, and relocated two shipping logistic individuals from our Denver, Colorado office to manage shipping. We also hired several local warehouse individuals to manage this process. We believe this efficiency will improve our shipping time and reduce our overall cost of goods sold.

Additionally, the Company has hired six new sales and marketing individuals to continue the expansion and growth of sales. The finance team has added four new staff members and our board of directors appointed a new Chief Financial Officer on July 1, 2012. New controls and procedures have been implemented over sales orders and discounting as well as new financial controls, budgeting processes, daily and monthly monitoring reports along with dashboard reporting for aiding management in making good decisions.

The Company has appointed a five member Board of Directors, three of which are independent by the board. The Company has also appointed an audit committee, and compensation committee. Regular board meetings are held and task lists are reviewed and checked off with members of outside counsel to mitigate issues and promote further improvements around internal controls and reporting which the Company believes is much improved but not yet complete.

Our failure to respond appropriately to competitive challenges, changing consumer preferences and demand for new products could significantly harm our customer relationships and product sales.

The nutritional sports supplement industry is characterized by intense competition for product offerings and rapid and frequent changes in consumer demand. Our failure to predict accurately product trends could negatively impact our products and cause our revenues to decline.

Our success with any particular product offering (whether new or existing) depends upon a number of factors, including our ability to:

Products often have to be promoted heavily in stores or in the media to obtain visibility and consumer acceptance. Acquiring distribution for products is difficult and often expensive due to slotting and other promotional charges mandated by retailers. Products can take substantial periods of time to develop consumer awareness, consumer acceptance and sales volume. Accordingly, some products may fail to gain or maintain sufficient sales volume and as a result may have to be discontinued. In a highly competitive marketplace it may be difficult to have retailers open stock-keeping units (sku’s) for new products.

Our management has determined that ourcertain disclosure controls and procedures aremay be ineffective, even though they have been improved upon, which could result in material misstatements in our financial statements.

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended, which we refer to as the Exchange Act. As of December 31, 2011,2012, our management determined that some of our disclosure controls and procedures were ineffective due to weaknesses in our financial closing process.

We intend to implement remedial measures designed to address the ineffectiveness of our disclosure controls and procedures.procedures, such as hiring several individuals with significant accounting, auditing and financial reporting experience and segregating our internal and external financial reporting among our larger financing and accounting staff, implementing more specific segregation of our accounting software and providing historical information more timely, such as monthly budgeting analysis and cash reporting. We have also adopted and implemented written procedures to document purchase orders, product discounts and product transition flow as well as analysis of our cost of goods sold. If these remedial measures are insufficient to address the ineffectiveness of our disclosure controls and procedures, or if material weaknesses or significant deficiencies in our internal control are discovered or occur in the future and the ineffectiveness of our disclosure controls and procedures continues, we may fail to meet our future reporting obligations on a timely basis, our consolidated financial statements may contain material misstatements, we could be required to restate our prior period financial results, our operating results may be harmed, we may be subject to class action litigation, and if we gain a listing on The NASDAQ Capital Market,a stock exchange, our common stock could be delisted from that exchange. Any failure to address the ineffectiveness of our disclosure controls and procedures could also adversely affect the results of the periodic management evaluations regarding the effectiveness of our internal control over financial reporting and our disclosure controls and procedures that are required to be included in our annual report on Form 10-K. Internal control deficiencies and ineffective disclosure controls and procedures could also cause investors to lose confidence in our reported financial information. We can give no assurance that the measures we plan to take in the future will remediate the ineffectiveness of our disclosure controls and procedures or that any material weaknesses or restatements of financial results will not arise in the future due to a failure to implement and maintain adequate internal control over financial reporting or adequate disclosure controls and procedures or circumvention of these controls. In addition, even if we are successful in strengthening our controls and procedures, in the future those controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our consolidated financial statements.

If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to disclosure controls and procedures, or, if we discover material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.

If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to disclosure controls and procedures, or, if we discover additional material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our common stock could drop significantly. In addition, we cannot be certain that additional material weaknesses or significant deficiencies in our internal controls will not be discovered in the future.

Our industry is highly competitive, and our failure to compete effectively could adversely affect our market share, financial condition and future growth.

The nutritional supplement industry is highly competitive with respect to:

Most of our competitors are larger more established and possess greater financial, personnel, distribution and other resources than we have. We face competition in the health food channel from a limited number of large nationally known manufacturers, private label brands and many smaller manufacturers of dietary supplements.

We rely on a limited number of customers for a substantial portion of our sales, and the loss of or material reduction in purchase volume by any of these customers would adversely affect our sales and operating results.

For the six monthsyear ended June 30,December 31, 2012, two of our customers accounted for an aggregate of approximately 46%45% of our sales. Our largest customer for the six monthsyear ended June 30,December 31, 2012, accounted for 35%33% of our sales. For the year ended December 31, 2011, two customers accounted for approximately 55% of our sales and our largest customer represented 41% of our sales.

For the yearthree months ended DecemberMarch 31, 2010, three2013, two of our customers accounted for an aggregate of approximately 67% of our sales and the largest customer accounted for 45%46% of our sales. Our largest customer for the three months ended March 31, 2013, accounted for 35% of our sales. For the three months ended March 31, 2012, two of our customers accounted for an aggregate of approximately 56% of our sales. Our largest customer for the three months ended March 31, 2012, accounted for 38% of our sales.

The loss of any of our major customers, a significant reduction in purchases by any major customer, or, any serious financial difficulty of a major customer, could have a material adverse effect on our sales and results of operations.

Adverse publicity or consumer perception of our products and any similar products distributed by others could harm our reputation and adversely affect our sales and revenues.

We believe we are highly dependent upon positive consumer perceptions of the safety and quality of our products as well as similar products distributed by other sports nutrition supplement companies. Consumer perception of sports nutrition supplements and our products in particular can be substantially influenced by scientific research or findings, national media attention and other publicity about product use. Adverse publicity from these sources regarding the safety, quality or efficacy of nutritional supplements and our products could harm our reputation and results of operations. The mere publication of news articles or reports asserting that such products may be harmful or questioning their efficacy could have a material adverse effect on our business, financial condition and results of operations, regardless of whether such news articles or reports are scientifically supported or whether the claimed harmful effects would be present at the dosages recommended for such products.

We rely on highly skilled personnel and, if we are unable to retain or motivate key personnel, hire qualified personnel, we may not be able to grow effectively.

Our performance largely depends on the talents and efforts of highly skilled individuals. Our future success depends on our continuing ability to identify, hire, develop, motivate and retain highly skilled personnel for all areas of our organization, particularly sales and marketing. Competition in our industry for qualified employees is intense. In addition, our compensation arrangements, such as our bonus programs, may not always be successful in attracting new employees or retaining and motivating our existing employees. Our continued ability to compete effectively depends on our ability to attract new employees and to retain and motivate our existing employees.

If we are unable to retain key personnel, our ability to manage our business effectively and continue our growth could be negatively impacted.

Our management employees include Brad J. Pyatt, L. Gary Davis, John H. Bluher, Richard Estalella, Jeremy R. DeLuca and Cory J. Gregory. These key management employees are primarily responsible for our day-to-day operations, and we believe our success depends in large part on our ability to retain them and to continue to attract additional qualified individuals to our management team. Currently, we have executed employment agreements with our key management employees. The loss or limitation of the services of any of our key management employees or the inability to attract additional qualified personnel could have a material adverse effect on our business and results of operations.

Our operating results may fluctuate, which makes our results difficult to predict and could cause our results to fall short of expectations.

Our operating results may fluctuate as a result of a number of factors, many of which may be outside of our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful, and you should not rely on our past results as an indication of our future performance. Our quarterly, year-to-date, and annual expenses as a percentage of our revenues may differ significantly from our historical or projected rates. Our operating results in future quarters may fall below expectations. Each of the following factors may affect our operating results:

Because our business is changing and evolving, our historical operating results may not be useful to you in predicting our future operating results.

The continuing effects of the most recent global economic crisis may impact our business, operating results, or financial condition.

The global economic crisis that began in 2008 has caused disruptions and extreme volatility in global financial markets and increased rates of default and bankruptcy, and has impacted levels of consumer spending. These macroeconomic developments could negatively affect our business, operating results, and financial condition. For example, if consumer spending decreases, this may result in lower sales.

We may be exposed to material product liability claims, which could increase our costs and adversely affect our reputation and business.

As a marketer and distributor of products designed for human consumption, we could be subject to product liability claims if the use of our products is alleged to have resulted in injury. Our products consist of vitamins, minerals, herbs and other ingredients that are classified as dietary supplements and in most cases are not subject to pre-market regulatory approval in the United States or internationally. Previously unknown adverse reactions resulting from human consumption of these ingredients could occur.

We have not had any product liability claims filed against us, but in the future we may be subject to various product liability claims, including among others that our products had inadequate instructions for use, or inadequate warnings concerning possible side effects and interactions with other substances. The cost of defense can be substantially higher than the cost of settlement even when claims are without merit. The high cost to defend or settle product liability claims could have a material adverse effect on our business and operating results.

Our insurance coverage or third party indemnification rights may not be sufficient to cover our legal claims or other losses that we may incur in the future.

We maintain insurance, including property, general and product liability, and workers’ compensation to protect ourselves against potential loss exposures. In the future, insurance coverage may not be available at adequate levels or on adequate terms to cover potential losses, including on terms that meet our customer’s requirements. If insurance coverage is inadequate or unavailable, we may face claims that exceed coverage limits or that are not covered, which could increase our costs and adversely affect our operating results.

Our intellectual property rights are valuable, and any inability to protect them could reduce the value of our products and brand.

We have invested significant resources to protect our brands and intellectual property rights. However, we may be unable or unwilling to strictly enforce our intellectual property rights, including our trademarks, from infringement. Our failure to enforce our intellectual property rights could diminish the value of our brands and product offerings and harm our business and future growth prospects.

We may be subject to intellectual property rights claims, which are costly to defend, could require us to pay damages and could limit our ability to sell some of our products.

Our industry is characterized by vigorous pursuit and protection of intellectual property rights, which has resulted in protracted and expensive litigation for several companies. Third parties may assert claims of misappropriation of trade secrets or infringement of intellectual property rights against us or against our end customers or partners for which we may be liable.

As our business expands, the number of products and competitors in our markets increases and product overlaps occur, infringement claims may increase in number and significance. Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, and we cannot be certain that we would be successful in defending ourselves against intellectual property claims. Further, many potential litigants have the capability to dedicate substantially greater resources than we can to enforce their intellectual property rights and to defend claims that may be brought against them. Furthermore, a successful claimant could secure a judgment that requires us to pay substantial damages or prevents us from distributing products or performing certain services.

An increase in product returns could negatively impact our operating results and profitability.

We permit the return of damaged or defective products and accept limited amounts of product returns in certain instances. While such returns have historically been nominal and within management’s expectations and the provisions established, future return rates may differ from those experienced in the past. Any significant increase in damaged or defective products or expected returns could have a material adverse effect on our operating results for the period or periods in which such returns materialize.

We have no manufacturing capacity and anticipate continued reliance on third-party manufacturers for the development and commercialization of our products.

We do not currently operate manufacturing facilities for production of our products. We lack the resources and the capabilities to manufacture our products on a commercial scale. We do not intend to develop facilities for the manufacture of products in the foreseeable future. We rely on third-party manufacturers to produce bulk products required to meet our sales needs. We plan to continue to rely upon contract manufacturers to manufacture commercial quantities of our products.

Our contract manufacturers’ failure to achieve and maintain high manufacturing standards, in accordance with applicable regulatory requirements, or the incidence of manufacturing errors, could result in consumer injury or death, product shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously harm our business. Contract manufacturers often encounter difficulties involving production yields, quality control and quality assurance, as well as shortages of qualified personnel. Our existing manufacturers and any future contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business. In the event of a natural disaster, business failure, strike or other difficulty, we may be unable to replace a third-party manufacturer in a timely manner and the production of our products would be interrupted, resulting in delays, additional costs and reduced revenues.

A shortage in the supply of key raw materials could increase our costs or adversely affect our sales and revenues.

All of our raw materials for our products are obtained from third-party suppliers. Since all of the ingredients in our products are commonly used, we have not experienced any shortages or delays in obtaining raw materials. If circumstances changed, shortages could result in materially higher raw material prices or adversely affect our ability to have a product manufactured. Price increases from a supplier would directly affect our profitability if we are not able to pass price increases on to customers. Our inability to obtain adequate supplies of raw materials in a timely manner or a material increase in the price of our raw materials could have a material adverse effect on our business, financial condition and results of operations.

Because we are subject to numerous laws and regulations, and we may become involved in litigation from time to time, we could incur substantial judgments, fines, legal fees and other costs.

Our industry is highly regulated. The manufacture, labeling and advertising for our products are regulated by various federal, state and local agencies as well as those of each foreign country to which we distribute. These governmental authorities may commence regulatory or legal proceedings, which could restrict the permissible scope of our product claims or the ability to manufacture and sell our products in the future. The U.S. Food and Drug Administration, or FDA, regulates our products to ensure that the products are not adulterated or misbranded. Failure to comply with FDA requirements may result in, among other things, injunctions, product withdrawals, recalls, product seizures, fines and criminal prosecutions. Our advertising is subject to regulation by the Federal Trade Commission, or FTC, under the Federal Trade Commission Act. In recent years the FTC has initiated numerous investigations of dietary supplement and weight loss products and companies. Additionally, some states also permit advertising and labeling laws to be enforced by private attorney generals, who may seek relief for consumers, seek class action certifications, seek class wide damages and product recalls of products sold by us. Any of these types of adverse actions against us by governmental authorities or private litigants could have a material adverse effect on our business, financial condition and results of operations.

Other RisksA member of our management team has been involved in a bankruptcy proceeding and Risks Relatingother failed business ventures that may expose us to this Offeringassertions that we are not able to effectively manage our business, which could have a material adverse effect on our business and your investment in our securities.

Our chief executive officer and co-chairman of our board of directors, Brad J. Pyatt, has been involved in a personal bankruptcy and other failed business ventures. This may expose us to assertions by others that our management team may not know how to effectively run a business. To address this risk, our board of directors has devoted significant time and energy to bolstering our management team with individuals who have public company experience and financial expertise, as well as adding independent board members. Notwithstanding these efforts, if our business partners and investors do not have confidence in our management team, it could have a material adverse effect on our business and your investment in our company.

Because certain of our stockholders control a significant number of shares of our common stock, they may have effective control over actions requiring stockholder approval.

As of July 9, 2013, our directors, executive officers, and their respective affiliates, beneficially own approximately 19.45% of our outstanding shares of common stock. Also, two of our executive officers own 51 shares of our Series B Preferred Stock, which has voting control of the Company. As a result, these stockholders, acting together, would have the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, would have the ability to control the management and affairs of our company. Accordingly, this concentration of ownership might harm the market price of our common stock by:

The conversion reset provision relating to our Series D Preferred Stock could result in difficulty for us to obtain future equity financing.

Because the conversion price reset provisions relating to our Series D Preferred Stock discussed above are so significant and to the potential detriment of common stockholders, it may make it more difficult for us to raise any future equity capital. This potential difficulty should be reviewed in light of our existing levels of little capital and significant working capital deficit. As of July 9, 2013 approximately 90% of the preferred stock issued in the Series D offering has been converted to common stock, greatly reducing this risk.

We may, in the future, issue additional shares of common stock, which would reduce investors’ percent of ownership and may dilute our share value.

Our articles of incorporation, as amended, authorize the issuance of 2,500,000,000100,000,000 shares of common stock and 10,000,000 shares of preferred stock, of which (i) 5,000,000 shares ofhave been designated as Series A Convertible Preferred Stock, (ii) 51 shares ofhave been designated as Series B Preferred Stock, and(iii) 500 shares ofhave been designated as Series C Convertible Preferred Stock and (iv) 1,600,000 shares have been designated as Series D Convertible Preferred Stock. The articles of incorporation authorize our board of directors to prescribe the series and the voting powers, designations, preferences, limitations, restrictions and relative rights of any undesignated shares of our preferred stock. The future issuance of common stock and preferred stock may result in substantial dilution in the percentage of our common stock held by our then existing stockholders. We may value any common stock or preferred stock issued in the future on an arbitrary basis. The issuance of common stock for future services or acquisitions or other corporate actions may have the effect of diluting the value of the shares held by our investors, and might have an adverse effect on any trading market for our common stock.

We may issue additional shares of preferred stock in the future that may adversely impact your rights as holders of our common stock.

Our articles of incorporation, as amended, authorize us to issue shares of preferred stock in various classes.series. Currently, we have 51 shares of Series B Preferred Stock issued and outstanding, which hasshares have voting control of the Company. Each share of our Series A Preferred Stock is convertible into 200 shares of our common stock although no shares of this series are outstanding. Each shares of our Series D Convertible Preferred Stock is convertible into two shares of our common stock. In addition, our board of directors will has the authority to fix and determine the relative rights and preferences of our authorized but undesignated preferred stock, as well as the authority to issue additional shares of such preferred stock, without further stockholder approval. As a result, our board of directors could authorize the issuance of a series of preferred stock that would grant to holders preferred rights to our assets upon liquidation, the right to receive dividends before dividends are declared to holders of our common stock, and the right to the redemption of such preferred stock, together with a premium, prior to the redemption of the common stock. To the extent that we do issue such additional shares of preferred stock, your rights as holders of common stock could be impaired thereby, including, without limitation, dilution of your ownership interests in us. In addition, shares of preferred stock could be issued with terms calculated to delay or prevent a change in control or make removal of management more difficult, which may not be in your interest as a holder of common stock.

Our common stock is quoted on the OTCBB which may have an unfavorable impact on our stock price and liquidity.

Our common stock is quoted on the OTCBB. The OTCBB is a significantly more limited market than the New York Stock Exchange or the NASDAQ Stock Market. The quotation of our shares on the OTCBB may result in a less liquid market available for existing and potential stockholders to trade shares of our common stock, could depress the trading price of our common stock and could have a long-term adverse impact on our ability to raise capital in the future.

LiabilityA DTC “Chill” on the electronic clearing of directors for breachtrades in our securities in the future may affect the liquidity of duty of care is limited.our stock and our ability to raise capital.

Under Because our common stock is considered a “penny stock,” there is a risk that the Depository Trust Company (DTC) may place a “chill” on the electronic clearing of trades in our securities. This may lead some brokerage firms to be unwilling to accept certificates and/or electronic deposits of our stock and other securities and also some may not accept trades in our securities altogether. In the past, DTC has placed a deposit chill on our shares, and although the chill is currently removed, no assurance can be given that a chill will not be reinstated in the future. A future DTC chill would affect the liquidity of our securities and make it difficult to purchase or sell our securities in the open market. It may also have an adverse effect on our ability to raise capital because investors may be unable to easily resell our securities into the market. Our inability to raise capital on terms acceptable to us, if at all, could have a material and adverse effect on our business and operations.

Nevada corporations laws limit the personal liability of corporate directors and officers and require indemnification under certain circumstances.

Section 78.138(7) of the Nevada Revised Statutes allprovides that, subject to certain very limited statutory exceptions or unless the articles of incorporation provide for greater individual liability, a director or officer of a Nevada corporations limitcorporation is not individually liable to the corporation or its stockholders for any damages as a result of any act or failure to act in his or her capacity as a director or officer, unless it is proven that the act or failure to act constituted a breach of his or her fiduciary duties as a director or officer and such breach involved intentional misconduct, fraud or a knowing violation of law. We have not included in our articles of incorporation any provision intended to provide for greater liability of directors and officers, including acts not in good faith. Our stockholders’ ability to recover damages for fiduciary breaches may be reducedas contemplated by this statute. statutory provision.

In addition, we are obligated to indemnify our directors and officers regarding stockholder suits which they successfully defend as set forth in Section 78.750278.7502(3) of the Nevada Revised Statutes.Statutes provides that to the extent a director or officer of a Nevada corporation has been successful on the merits or otherwise in the defense of certain actions, suits or proceedings (which may include certain stockholder derivative actions), the corporation shall indemnify such director or officer against expenses (including attorneys’ fees) actually and reasonably incurred by such director or officer in connection therewith.

BecauseYou may experience substantial dilution in the event we issue common stock in the future at a price below $4.00 per share.

The terms of the Series D Preferred Stock require us to increase the conversion rate in the event we issue common stock below $4.00 per share while any shares of Series D Preferred stock are outstanding, resulting in additional shares of common stock issuable upon conversion of shares of Series D Preferred Stock. For example, if we issue shares of common stock for little or no consideration, the certificate of designation for the Series D Preferred Stock provides that such issuance will be deemed to be issued at $0.001 per share of common stock, which would have broad discretiona substantial impact on the conversion rate of the Series D Preferred Stock, and flexibility in howyour ownership percentage of the net proceeds from this offering are used, we may use the net proceeds in ways in which you disagree.Company and likely, its value, would decrease accordingly.

We currently intend to use the net proceeds from this offering to repay $3.5 million of debt due upon completion of this offering, for working capital and other general corporate purposes. See “Use of Proceeds” on page 18 of this prospectus. Other than the debt payments, we have not allocated specific amounts of the net proceeds from this offering for any of the foregoing purposes. Accordingly, our management will have significant discretion and flexibility in applying these proceeds. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the net proceeds are being used appropriately. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for us. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, operating results and cash flow.

Future financings through debt securities and preferred stock may restrict our operations.

If additional funds are raised through a credit facility or the issuance of debt securities or preferred stock, lenders under the credit facility or holders of these debt securities or preferred stock would likely have rights that are senior to the rights of holders of our common stock, and any credit facility or additional securities could contain covenants that would restrict our operations.

Our common stock price may be volatile and could fluctuate widely in price, which could result in substantial losses for investors.

The market price of our common stock has historically been and is likely to be highly volatile and could fluctuate widely in price in response to various factors, many of which are beyond our control, including:

If our common stock remainsbecomes subject to the SEC’s penny stock rules, broker-dealers may experience difficulty in completing customer transactions and trading activity in our securities may be adversely affected.

Unless our securities are listed on a national securities exchange, or we have net tangible assets of $5.0 million or more and our common stock has a market price per share of $5.00 or more, transactions in our common stock will be subject to the SEC’s “penny stock” rules. If our common stock remains subject to the “penny stock” rules promulgated under the Exchange Act, broker-dealers may find it difficult to effectuate customer transactions and trading activity in our securities may be adversely affected.

Under these rules, broker-dealers who recommend such securities to persons other than institutional accredited investors must:

As a result, if our common stock becomes or remains subject to the penny stock rules, the market price of our securities may be depressed, and you may find it more difficult to sell our securities.

Because certain of our stockholders control a significant number of shares of our common stock they may have effective control over actions requiring stockholder approval.

Asafter conversion of October 25, 2012, our directors, executive officers and principal stockholders, and their respective affiliates, beneficially own approximately 21.7% of our outstanding shares of common stock. Also, two of our executive officers own 51 shares of our Series BD Preferred Stock, which has voting control of the Company. As a result, these stockholders, acting together, would have the ability to control the outcome of matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, would have the ability to control the management and affairs of our company. Accordingly, this concentration of ownership might harm the market price of our common stock by:Stock.

We have not paid dividends on our common stock in the past and do not expect to pay dividends on our common stock for the foreseeable future. Any return on investment may be limited to the value of our common stock.

No cash dividends have been paid on our common stock. We expect that any income received from operations will be devoted to our future operations and growth. We do not expect to pay cash dividends on our common stock in the near future. Payment of dividends would depend upon our profitability at the time, cash available for those dividends, and other factors as our board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on an investor’s investment will only occur if our stock price appreciates. Investors in our common stock should not rely on an investment in our company if they require dividend income.

If securities or industry analysts do not publish research or reports about our business, or if they change their recommendations regarding our stock adversely, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. We do not currently have and may never obtain research coverage by industry or financial analysts. If no or few analysts commence coverage of us, the trading price of our stock would likely decrease. Even if we do obtain analyst coverage, if one or more of the analysts who cover us downgrade our stock, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

A sale of a substantial number of shares of our common stock including the Resale Shares registered herein may cause the price of our common stock to decline and may impair our ability to raise capital in the future.

Our common stock is traded on the OTCBB and, despite certain increases of trading volume from time to time, there have been periods when it could be considered “thinly-traded”, meaning that the number of persons interested in purchasing our common stock at or near bid prices at any given time may be relatively small or non-existent. Finance transactions resulting in a large amount of newly issued shares that become readily tradable, or other events that cause current stockholders to sell shares, could place downward pressure on the trading price of our stock. In addition, the lack of a robust resale market may require a stockholder who desires to sell a large number of shares of common stock to sell the shares in increments over time to mitigate any adverse impact of the sales on the market price of our stock.

If our stockholders sell, or the market perceives that our stockholders intend to sell for various reasons, including the ending of restrictions on resale of substantial amounts of our common stock in the public market, including shares issued upon the exercise of outstanding options, the market price of our common stock could fall. Sales of a substantial number of shares of our common stock may make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate. We may become involved in securities class action litigation that could divert management’s attention and harm our business.

You will experience immediate and substantial dilution as a result of this offering and may experience additional dilution in the future.

You will incur immediate and substantial dilution as a result of this offering. After giving effect to the sale by us of up to   shares offered in this offering at an assumed public offering price of $ per share, and after deducting the underwriter’s discounts and commissions and estimated offering expenses payable by us, investors in this offering can expect an immediate dilution of $ per share. In addition, in the past, we issued options and warrants to acquire shares of common stock. To the extent these options are ultimately exercised, you will sustain future dilution. We may also acquire or license other technologies or finance strategic alliances by issuing equity, which may result in additional dilution to our stockholders.

Risks Related to Our Reverse Stock Split

We intend to effect a 1-for-650 reverse stock split of our outstanding common stock immediately prior to this offering. However, the reverse stock split may not increase our stock price sufficiently and we may not be able to list our common stock on The NASDAQ Capital Market, in which case this offering will not be completed.

We expect that the 1-for-650 reverse stock split of our outstanding common stock will increase the market price of our common stock so that we will be able to meet the minimum bid price requirement of the Listing Rules of The NASDAQ Capital Market. However, the effect of a reverse stock split upon the market price of our common stock cannot be predicted with certainty, and the results of reverse stock splits by companies in similar circumstances have been varied. It is possible that the market price of our common stock following the reverse stock split will not increase sufficiently for us to be in compliance with the minimum bid price requirement. If we are unable meet the minimum bid price requirement, we may be unable to list our shares on The NASDAQ Capital Market, in which case this offering will not be completed.

Even if the reverse stock split achieves the requisite increase in the market price of our common stock, we cannot assure you that we will be able to continue to comply with the minimum bid price requirement of The NASDAQ Capital Market.

Even if the reverse stock split achieves the requisite increase in the market price of our common stock to be in compliance with the minimum bid price of The NASDAQ Capital Market, there can be no assurance that the market price of our common stock following the reverse stock split will remain at the level required for continuing compliance with that requirement. It is not uncommon for the market price of a company’s common stock to decline in the period following a reverse stock split. If the market price of our common stock declines following the effectuation of a reverse stock split, the percentage decline may be greater than would occur in the absence of a reverse stock split. In any event, other factors unrelated to the number of shares of our common stock outstanding, such as negative financial or operational results, could adversely affect the market price of our common stock and jeopardize our ability to meet or maintain The NASDAQ Capital Market’s minimum bid price requirement. In addition to specific listing and maintenance standards, The NASDAQ Capital Market has broad discretionary authority over the initial and continued listing of securities, which it could exercise with respect to the listing of our common stock.

Even if the reverse stock split increases the market price of our common stock, there can be no assurance that we will be able to comply with other continued listing standards of The NASDAQ Capital Market.

Even if the market price of our common stock increases sufficiently so that we comply with the minimum bid price requirement, we cannot assure you that we will be able to comply with the other standards that we are required to meet in order to maintain a listing of our common stock on The NASDAQ Capital Market. Our failure to meet these requirements may result in our common stock being delisted from The NASDAQ Capital Market, irrespective of our compliance with the minimum bid price requirement.

The reverse stock split may decrease the liquidity of the shares of our common stock.

The liquidity of the shares of our common stock may be affected adversely by the recently effected 1-for-850 reverse stock split given the reduced number of shares that will be outstanding following the reverse stock split, especially if the market price of our common stock does not increase as a result of the reverse stock split. In addition, the reverse stock split may increasehave increased the number of stockholders who own odd lots (less than 100 shares) of our common stock, creating the potential for such stockholders to experience an increase in the cost of selling their shares and greater difficulty effecting such sales.

Following the reverse stock split, the resulting market price of our common stock may not attract new investors, including institutional investors, and may not satisfy the investing requirements of those investors. Consequently, the trading liquidity of our common stock may not improve.

Although we believe that a higher market price of our common stock may help generate greater or broader investor interest, there can be no assurance that the recently effected 1-for-850 reverse stock split will result in a share price that will attract new investors, including institutional investors. In addition, there can be no assurance that the market price of our common stock will satisfy the investing requirements of those investors. As a result, the trading liquidity of our common stock may not necessarily improve.

USE OF PROCEEDS

We estimate that our net proceeds from the sale of the common stock offered pursuant to this prospectus will be approximately $          million, or approximately $          million if the underwriters exercise in full their option to purchase          additional shares, based upon the public offering price of $          per share and after deducting the underwriting discount and the estimated offering expenses that are payable by us.

We currently intend to use the net proceeds that we receive in this offering as follows: (i) $3.6 million for working capital; (ii) $3.4 million for repayment of our outstanding debt balance principal amount of debt held by non-affiliated parties, which will be due upon completion of this offering (as set forth below), (iii) to pay interest of approximately $0.1 million, representing interest payable, (iv) $1.4 million for aged accounts payable; (v) $6.0 million for inventory and related items; (vi) $2.0 million for international marketing development; and (vii) and the remainder for general corporate purposes.

Our outstanding indebtedness that will be repaid is as follows:

PRICE RANGE OF COMMON STOCK

Our shares of common stock were cleared for trading under the symbol “TTWZ:OB” on the OTCBB on November 24, 2008, and later began trading on the OTCBB under the symbol “MSLP:OB” on April 22, 2010. Prior to this period, there was minimal trading in our common stock. The following table shows the reported high and low bid quotations per share for our common stock based on information provided by the OTCBB. These prices reflect the expected 1-for-6501-for-850 reverse stock split of our common stock that we intend to effect prior to the date of this prospectus.effected on November 26, 2012.

Quotations on the OTCBB reflect bid and ask quotations, may reflect inter-dealer prices, without retail markup, markdown or commission, and may not represent actual transactions. In periods prior to April 22, 2010, there was no volume in our common stock. The closing price of our common stock on July 9, 2013 was $10.85 per share.

As of October 25, 2012,July 9, 2013, there were approximately 420324 holders of record of our common stock. This figure does not take into account those stockholders whose certificates are held in street name by brokers and other nominees. We estimate that such holders number approximately 3,700.

DIVIDEND POLICY

We have never declared dividends on our common stock, and currently do not plan to declare dividends on shares of our common stock in the foreseeable future. We expect to retain our future earnings, if any, for use in the operation and expansion of our business. Subject to the foregoing, the payment of cash dividends in the future, if any, will be at the discretion of our board of directors and will depend upon such factors as earnings levels, capital requirements, our overall financial condition and any other factors deemed relevant by our board of directors.

DILUTION

If you invest in our common stock, your interest will be immediately and substantially diluted to the extent of the difference between the public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock after giving effect to this offering.

Our pro forma net tangible book value as of June 30, 2012 was $(     ) or $(     ) per share of common stock, based upon [   ] shares outstanding, after giving effect to issuances of common stock from July 1, 2012 through and immediately prior to the date of this offering. After giving effect to the sale of the shares in this offering at the assumed public offering price of $ per share, at June 30, 2012, after deducting underwriting discounts and commissions and other estimated offering expenses payable by us, our pro forma as adjusted net tangible book value at June 30, 2012 would have been approximately , or $ per share. This represents an immediate increase in pro forma net tangible book value of approximately $ per share to our existing stockholders, and an immediate dilution of $    per share to investors purchasing shares in the offering.

Dilution in pro forma net tangible book value per share represents the difference between the amount per share paid by purchasers of our common stock in this offering and the pro forma net tangible book value per share of our common stock immediately after this offering.

The following table illustrates the per share dilution to investors purchasing shares in the offering:

The information above assumes that the underwriters do not exercise their over-allotment option. If the underwriters exercise their over-allotment option in full, the pro forma as adjusted net tangible book value will increase to $ per share, representing an immediate increase to existing stockholders of $ per share and an immediate dilution of $ per share to new investors. If any shares are issued upon exercise of outstanding options or warrants, new investors will experience further dilution.

Liquidity and Capital Resources

The following table summarizes total current assets, liabilities and working capital deficit at June 30,December 31, 2012, compared to December 31, 2011:

Our primary source of operating cash has been throughfrom the sale of equity, and the issuance of convertible secured promissory notes and other short termshort-term debt as discussed below.

Company’s management believes that with increased sales expansion and the opening of the Franklin, Tennessee distribution center, there will be opportunities to increase sales; however, the Company may need to continue to raise capital in order execute the business plan, which includes buying more inventory and broadening the sales platform. There can be no assurance that such capital will be available on acceptable terms or at all.

On December 4, 2012, we entered into a $1.0 million bridge loan to provide us with short-term financing.  In connection with the bridge loan, we entered into a subscription agreement with six subscribers pursuant to which we issued an aggregate of $1.0 million principal amount of promissory notes and 50,000 shares of common stock to the subscribers.  The promissory notes were repaid in January 2013.  Additionally, we granted the subscribers “piggy-back” registration rights for the shares of common stock in certain circumstances.

At June 30,December 31, 2012, we had cash of approximately $.3 million$0 and a working capital deficit of approximately $12.7$11.6 million, compared to cash of approximately $.7$0.7 million and a working capital deficit of approximately $13.7 million at December 31, 2011.

The working capital deficit decrease of approximately $2.1 million was primarily due to a net decrease in derivative liabilities of approximately $7.0 million, an increase in accounts receivable of approximately $.7 million, offset by an increase in customer deposits of approximately $0.3 million, an increase in the current portion of debt of approximately $3.2 million and an increase in accounts payable and accrued liabilities of approximately $2.4million.

Cash provided byused in operating activities was approximately $.4$0.7 million for the six monthsyear ended June 30,December 31, 2012, as compared to cash used in operating activities of approximately $2.6$5.8 million for the six monthsyear ended June 30,December 31, 2011. The increasedecrease in cash used in operating activities of approximately $3.0$5.1 million for the six months ended June 30, 2012, compared to the six months ended June 30, 2011, was primarily due to a decrease in net loss of approximately $4.3 million, an increased payables and deferred revenuescustomer deposits of approximately $1.0$4.3 million, an increase in depreciation and amortization of approximately $0.3 million, a decrease in accounts receivable of approximately $1.5 million and an increase in amortization expense of approximately $2.3 offset by a decrease in stock and warrants issued for services of approximately $3.4 million, a decrease in losses related to repayments and conversions of debt of approximately $0.6 million, a decrease in derivative expense and fair value changes of approximately $1.1 million and a increases in prepaids, inventory, and other assets of approximately $1.2 million.

Cash used in investing activities increased to approximately $.6 million$965,327 from approximately $.3 million$831,511 for the six monthsyear ended June 30,December 31, 2012 and 2011, respectively, due to slightly higher spending on fixed assets. Future investments in property and equipment, as well as further development of our Internet presence will largely depend on available capital resources.

Going ConcernResults of Operations

For the Three Months Ended March 31, 2013 and 2012 (unaudited):

Sales - gross

Gross sales increased approximately $5.6 million or 29% to $24,924,000 for the three months ended March 31, 2013, compared to $19,303,000 for the three months ended March 31, 2012. The increase in sales was due primarily to increased awareness of our product brand, combined with hiring additional sales and marketing staff, and adding new products in an effort to expand our customer base. Since inception, we have focused on an aggressive marketing plan to penetrate the market. As reflectedsuch, significant promotional expenditures have been made to increase product sales through adding new customers and expanding our product line.

Overall as a direct result of our aggressive marketing plan, our products are currently being offered in more retail stores, both domestically and internationally, receiving better shelf placement, and receiving recognized awards compared to the accompanying unaudited interim consolidated financial statements,prior period. At the 2012 Bodybuilding.com Supplement Awards, we received three Awards of Excellence; (i) the “Brand of the Year” award, (ii) the “Packaging of the Year” award, and (iii) the “Pre-Workout Supplement of the Year” award for Assault^TM , and MusclePharm remains the product of choice for the Ultimate Fighting Championship, UFC.

Discounts and sales allowances

Discounts and sales allowances for the three months ended March 31, 2013 decreased to approximately $2,363,000 as compared to $2,742,000 for the three months ended March 31, 2012. This decrease is driven by the continued efforts to place controls around this area and greater efforts to define customer terms and allowances.

Other Income (Expenses)

Other expenses were $6,641,000 for the three months ended March 31, 2013, compared to the $15,308,000 for the three months ended March 31, 2012. During the three months ended March 31, 2013, the Company issued warrants to convert 1,500,000 shares of preferred stock into 3,000,000 shares of common stock. Refer to Note 5 for further detail of costs related to derivative agreements.

Net Loss

For the foregoing reasons, we had a net loss of approximately $9.9 million$7,362,000 for the sixthree months ended June 30, 2012, and had a working capital deficit and stockholders’ deficit of $12.7 million andMarch 31, 2013, compared to approximately $11.0 million at June 30, 2012 and 2011, respectively. These factors raise substantial doubt about our ability to continue as a going concern.$16,036,000 for the three months ended March 31, 2012.

Our ability to continue our operations is dependentInflation did not have a material impact on management’s plans, which include the raising of capital through debt and/or equity markets with some additional funding from other traditional financing sources, including term notes, sale of aged debt to third parties in exchange for stock, until such time that funds provided by operations are sufficient to fund working capital requirements. We may need to incur liabilities with certain related parties to sustain our existence.

We will require additional funding to finance the growth of our current and expected future operations as well as to achieve our strategic objectives. We believe our current available cash along with anticipated revenues will be insufficient to meet our cash needs for the near future. There can be no assurance that financing will be available in amounts or terms acceptable to us, if at all.

We anticipate that the net proceeds from this offering will fund our operations for approximately [ ] months.the period. Other than the foregoing, management knows of no trends, demands, or uncertainties that are reasonably likely to have a material impact on our results of operations.

In response to these capital issues, management has taken the following actions:Liquidity and Capital Resources

The following table summarizes total current assets, liabilities and working capital at March 31, 2013, compared to December 31, 2012.

Financing

Our primary source of operating cash has been through the sale of equity and through the issuance of convertible secured promissory notes and unsecured promissory notes. We continue to explore potential sales expansion opportunities in order to boost sales, while leveraging distribution systems to consolidate lower costs. We need to continue to raise capital in order execute the business plan.other short-term debt as discussed below.

On March 27, 2013, MusclePharm sold an aggregate of 703,236 shares of its common stock, $0.001 par value per share (the “Common Stock”) at a per share price of $8.50 in a private placement (the “Private Placement”) to certain accredited investors (the “Purchasers”) for an aggregate purchase price of approximately $5,977,506, thereby providing working capital.

The Common Stock was sold pursuant to subscription agreements dated March 27, 2013 (the “Subscription Agreements”) between the Company and the Purchasers. The Subscription Agreements contained customary terms regarding, among other things, representations and warranties and indemnification.

At March 31, 2013, we had cash of $8,483,000 and working capital of approximately $5,673,000, compared to cash of $0 and a working capital deficit of approximately $11,571,000 at December 31, 2012. The working capital increase of approximately $17,243,000 was primarily due to a net increase in cash of $8,493,000, an increase in accounts receivable of $4,726,000 and a decrease in current portion of debt of $4,008,000.

Cash used in operating activities was $3,206,969 for the three months ended March 31, 2013, as compared to cash provided by operating activities of $1,423,375 for the three months ended March 31, 2012. The increase in cash used in operating activities of approximately $4.6 million for the three months ended March 31, 2013, compared to the three months ended March 31, 2012, was primarily due to a decrease in payables and customer deposits of approximately $2.5 million, a decrease in depreciation and amortization of approximately $2 million, an increase in accounts receivable of approximately $2.5 million, a decrease in loss on settlement of accounts payable of approximately $3.2 million and a decrease in derivative expense and change in fair value of derivatives of approximately $3.7 million offset by a decrease net loss of approximately $8.7 million.

Cash used in investing activities decreased to $234,573 from $305,781 for the three months ended March 31, 2013 and 2012, due to slightly lower spending on fixed assets. Future investments in property and equipment, as well as further development of our Internet presence will largely depend on available capital resources.

Cash flows provided by financing activities were $11,922,620 for the three months ended March 31, 2013, compared to cash flows used in financing activities of $478,123 for the three months ended March 31, 2012. The approximately $12.4 million increase was due to primarily to the net increase of approximately $16.1 million net proceeds from equity offerings and a decrease of approximately $0.1 million in repurchases of shares, offset by a decrease of approximately $2.8 million in proceeds from issuance of debt and an increase in debt repayment of approximately $1 million.

Cash Flows From Financing Activities:

Off-Balance Sheet Arrangements

Other than the operating leases, as of March 31, 2013, we did not have any off-balance sheet arrangements. We are obligated under an operating lease for the rental of office space. Future minimum annual lease payments for the above leasesrental commitments with a remaining term in excess of one year as of March 31, 2013 are approximately as follows:

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principlesGAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate could change in the near term due to one or more future non-conforming events. Accordingly, the actual results could differ significantly from estimates.

Risks and Uncertainties

We operate in an industry that is subject to rapid change and intense competition. Our operations are subject to significant risk and uncertainties including financial, operational, technological, regulatory and other risks, including the potential risk of business failure.

Principles of Consolidation

All intercompany accounts and transactions have been eliminated in consolidation.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable represents trade obligations from customers that are subject to normal trade collection terms. The accounts receivable are sent directly to our third party manufacturer and netted with any outstanding liabilities to the manufacturer. Liabilities to the manufacturer totaled approximately $2.4 million at June 30, 2012, and are included in accounts payable and accrued liabilities. We periodically evaluate the collectability of our accounts receivable and considerconsiders the need to establish an allowance for doubtful accounts based upon historical collection experience and specific customer information. Accordingly, the actual amounts could vary from the recorded allowances. There is also a review of customer discounts at the period end and an accrual made for discounts earned but not yet received by quarter end.

We perform ongoing evaluations of our customers’ financial condition and generally do not require collateral. Management reviews accounts receivable periodically and reduces the carrying amount by a valuation allowance that reflects management’s best estimate of amounts that may not be collectible. Allowances, if any, for uncollectible accounts receivable are determined based upon information available and historical experience.

We do not charge interest on past due receivables. Receivables are determined to be past due based on the payment terms of the original invoices.

Fair Value of Financial Instruments

We measure assets and liabilities at fair value based on an expected exit price as defined by the authoritative guidance on fair value measurements, which represents the amount that would be received on the sale of an asset or paid to transfer a liability, as the case may be, in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. We believe theThe authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level.

The following are the hierarchical levels of inputs to measure fair value:

The following are the major categories of liabilities measured at fair value on a recurring basis as of June 30, 2012 and December 31, 2011, using quoted prices in active markets for identical liabilities (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3):

Our financial instruments consisted primarily of accounts receivable, prepaids, accounts payable and accrued liabilities, debt and customer deposits. Our debt approximates fair value based upon current borrowing rates available to us for debt with similar maturities. The carrying amounts of our financial instruments generally approximated their fair values as of June 30, 2012 and December 31, 2011, respectively, due to the short-term nature of these instruments.

Revenue Recognition

We record revenue when all of the following have occurred: (1) persuasive evidence of an arrangement exists, (2) product has been shipped or delivered, (3) the sales price to the customer is fixed or determinable, and (4) collectability is reasonably assured.

Depending on individual customer agreements, sales are recognized either upon shipment of products to customers or upon delivery. For allWe record sales allowances and discounts as a direct reduction of our Canadian sales, which represented 2.0% and 0% of sales for the six month periods ended June 30, 2012 and 2011, respectively, and for one of our largest domestic customers, which represented 11% and 11% of our sales for the six month periods ended June 30, 2012 and 2011, respectively, and 11% of our sales for the six months ended June 30, 2012, revenue is recognized upon delivery.sales.

We have determined that advertising related credits that were granted to customers fell within the guidance of ASC No. 605-50-55 (“Revenue Recognition” – Customer Payments and Incentives – Implementation Guidance and Illustrations). The guidance indicates that, absent evidence of benefit to the vendor, appropriate treatment requires netting these types of payments against revenues and not expensing as advertising expense.

We record store support, giveaways, sales allowances and discounts as a direct reduction of sales.

We have an informal seven day right ofto return for our products. There were nominal returns for the year ended December 31, 2011 and forat the three and six monthsmonth periods ended June 30,March 31, 2013 and 2012.

Foreign Currency

We began operations in Canada in April 2012. The Canadian Dollar was determined to be the functional currency as the majority of the transactions related to the day to day operations of the business are exchanged in Canadian Dollars. At the end of the period, the financial results of the Canadian operation are translated into the United States Dollar,Dollars, which is the reporting currency, and added to the U.S. operations for consolidated company financial results. The revenue and expense items are translated using the average rate for the period and the assets and liabilities at the end of period rate. Transactions that have completed the accounting cycle and resulted in a gain or loss related to translation are recorded in realized gain or loss due to foreign currency translation under other income expense on the income statement. Transactions that have not completed their accounting cycle but appear to have gain or loss due to the translation process are recorded as unrealized gain or loss due to translation and held in the equity section on the balance sheet until such date the accounting cycle of a transaction is complete and the actual realized gain or loss is recognized.

Accounts Receivable

We perform ongoing evaluations of our customers’ financial condition and generally do not require collateral. Our management reviews accounts receivable periodically and reduces the carrying amount by a valuation allowance that reflects management’s best estimate of amounts that may not be collectible. Allowances, if any, for uncollectible accounts receivable are determined based upon information available and historical experience.

Beneficial Conversion Feature

For conventional convertible debt where the rate of conversion is below market value, we record a “beneficial conversion feature” (“BCF”) and related debt discount.

When we record a BCF, the relative fair value of the BCF iswould be recorded as a debt discount against the face amount of the respective debt instrument. The discount iswould be amortized to interest expense over the life of the debt.

Derivative Liabilities

Fair value accounting requires bifurcation of embedded derivative instruments such as conversion features in convertible debt or equity instruments, and measurement of their fair value for accounting purposes. In determining the appropriate fair value, we use the Black-Scholes option-pricing model. In assessing the convertible debt instruments, our management determines if the convertible debt host instrument is conventional convertible debt and further if there is a beneficial conversion feature requiring measurement. If the instrument is not considered conventional convertible debt, we will continue our evaluation process of these instruments as derivative financial instruments.

Once determined, derivative liabilities are adjusted to reflect fair value at each reporting period end, with any increase or decrease in the fair value being recorded in results of operations as an adjustment to fair value of derivatives. In addition, the fair value of freestanding derivative instruments such as warrants, are also valued using the Black-Scholes option-pricing model.

Debt Issue Costs and Debt Discount

We may pay debt issue costs, and record debt discounts in connection with raising funds through the issuance of convertible debt. These costs are amortized over the life of the debt to interest expense. If a conversion of the underlying debt occurs, a proportionate share of the unamortized amounts is immediately expensed.

Original Issue Discount

For certain convertible debt issued, we provide the debt holder with an original issue discount. The original issue discount is recorded to debt discount and additional paid in capital at an amount not to exceed gross proceeds raised, reducing the face amount of the debtnote and is amortized to interest expense over the life of the debt.

Share-Based Payments

Generally, all forms of share-based payments, including stock option grants, warrants, restricted stock grants and stock appreciation rights are measured at their fair value on the awards’ grant date, based on estimated number of awards that are ultimately expected to vest. Share-based compensation awards issued to non- employees for services rendered are recorded at either the fair value of the services rendered or the fair value of the share-based payment, whichever is more readily determinable.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04 “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. Generally Accepted Accounting Principles (“GAAP”)GAAP and International Financial Reporting Standards (“IFRS”). ASU 2011-04 includes common requirements for measurement of and disclosure about fair value between U.S. GAAP and IFRS. ASU 2011-04 requires reporting entities to disclose additional information for fair value measurements categorized within Level 3 of the fair value hierarchy. In addition, ASU 2011-04 requires reporting entities to make disclosures about amounts and reasons for all transfers in and out of Level 1 and Level 2 fair value measurements. The new and revised disclosures are effective for interim and annual reporting periods beginning after December 15, 2011. This pronouncement has been implemented in the Company’s financial statements for the year ended December 31, 2012 without impact.

InSince 2011, we becamehave been the official supplement provider and sponsor of the Ultimate Fighting Championship, or UFC. Our sponsorship includes prominent logo placement on the fighting mat, and our branding can be seen on FOX Television Stations, FX Networks, FUEL TV and Pay-Per-View television worldwide. The UFC fighters we sponsor feature our brand on their uniforms and we also extensively advertise at the UFC events.

We are also currently engaged in various in-store promotions, including point-of-purchase stands, aisle displays in retail outlets, as well as sample demonstrations in Dick’s Sporting Goods, GNC, Vitamin World and Vitamin Shoppe.

In 2011, we launched an advanced website in seeking to tap into the social networking world and to further our brand and consumer awareness. The information in our website is not part of this prospectus. We have included our website address as a factual reference and do not intend it to be an active link to our website. Also, we currently have over 250,000617,000 fans combined between our company and executive officer Facebook and Twitter accounts.

Industry Overview

We operate within the large and growing U.S. nutritional supplements industry. According to Nutrition Business Journal’s 2012 Supplement Business Report, our industry generated over $30 billion in sales in 2011 and $28.1 billion in 2010, and is projected to grow at an average annual rate of approximately 6.0% through 2020.

According to Nutrition Business Journal, sports nutrition products represented approximately 12% of the total sales in the U.S. nutritional supplements industry in 2011, and the category is expected to grow at a 9.1% compound annual growth rate (or CAGR) from 2012 to 2020, representing the fastest growing product category in the nutritional supplements industry.

We believe there are several key demographic, healthcare and lifestyle trends driving the continued growth of our industry. These trends include:

Participants in our industry include specialty retailers, supermarkets, drugstores, mass merchants, multi-level marketing organizations, online retailers, mail-order companies and a variety of other small participants. The nutritional supplements sold through these channels are divided into four major product categories: vitamins, minerals and health supplements; sports nutrition products; diet products; and other wellness products. Most supermarkets, drugstores and mass merchants have narrow nutrition supplement product offerings limited primarily to simple vitamins and herbs, with less knowledgeable sales associates than specialty retailers.

Our Products

We currently offer 2028 athlete-focused, high quality nutritional supplement products. None of our products are formulated to contain substances that have been the subject of publicized health concerns by the medical community such as ephedra, androstene, androstenedione, aspartame, steroids or human growth hormones. Our products are comprised of amino acids,vitamins, minerals, herbs and herbal extracts, carbohydrates, proteins and amino acids tested by our recognized scientists, and intended to be safe and effective for the overall health of athletes. Moreover, our nutritional supplements are intended to enhance the effects of workouts, repair muscles,support muscle recovery and strength, and nourish the human body for optimal physical fitness. The following is a brief description of our current products:

MusclePharm Apparel

We granted an exclusive indefinite license to market, manufacture, design and sell our existing apparel line. The licensee paid an initial fee of $250,000 in June, 2011 and will pay us a 10% net royalty based on the licensee’s net income at the end of each fiscal year. As of June 30, 2012,March 31, 2013, we had not earned any royalty revenue under this licensing arrangement.

Quality in Our Products

In seeking quality in our products, we require that before a product is brought to market, all:

Future Products

New products are derived from a number of sources, including our management, trade publications, scientific and health journals, consultants and distributors. Prior to introducing new products, we investigate product formulations as they relate to regulatory compliance and other issues. We expect to formulate between 10 to 20 new products within the next 12 to 18 months after the date of this prospectus.

Research and Development

Each of our products is the end result of a six stage process involving recognized nutrition scientists, doctors and professional athletes. Our expenses for research and development for the years ended December 31, 20102012 and 2011, were approximately $1.3$0.2 million and $.1$0.1 million, respectively and $.1 million for the six monthsquarter ended June 30, 2012.March 31, 2013 and 2012, were approximately $0.02 million and $0.1 million, respectively.

Management Information, Internet and Telecommunication Systems

The ability to efficiently manage distribution, compensation, inventory control, and communication functions through the use of sophisticated and dependable information processing systems is critical to our success.

We continue to invest in applications and integrations to improve and optimize business processes and to increase performance company wide.

Product Returns

We provide an informal seven day right of return for our products. Historically, product returns as a percentage of our net sales have been nominal.

Trademarks and Patents

We regard our trademarks and other proprietary rights as valuable assets and believe that protecting our key trademarks is crucial to our business strategy of building strong brand name recognition. These trademarks are crucial elements of our business, and have significant value in the marketing of our products.

Our policy is to pursue registrations for all of the trademarks associated with our products. Federally registered trademarks have a perpetual life, provided that they are maintained and renewed on a timely basis and used correctly as trademarks, subject to the rights of third parties to attempt to cancel a trademark if priority is claimed or there is confusion of usage. We rely on common law trademark rights to protect our unregistered trademarks. Common law trademark rights generally are limited to the geographic area in which the trademark is actually used, while a United States federal registration of a trademark enables the registrant to stop the unauthorized use of the trademark by any third party anywhere in the United States. Furthermore, the protection available, if any, in foreign jurisdictions may not be as extensive as the protection available to us in the United States.

Although we seek to ensure that we do not infringe on the intellectual property rights of others, there can be no assurance that third parties will not assert intellectual property infringement claims against us.

We have obtained U.S. registration on trademarks for 20eight of our products with USPTO applications pending on several of our newest products. We have abandoned or not pursued efforts to register marks identifying other items in our product line for various reasons including the inability of some names to qualify for registration. We also received federal trademark registration for 2014 names or expressions that we use or intend to use to distinguish ourselves from others.others, with several USPTO applications pending. All trademark registrations are protected for an initial period of five years and then are renewable after five years if still in use and every 10 years thereafter.

We have filed for a provisional patent to protect technology used in certain of our products, including MusclePharm Musclegel® and Re-Con®. The patent was filed in the United States as a Patent Cooperation Treaty (PCT) application to secure patent protection worldwide. We currently expect theAn International Search Report (ISR)/Written Opinion to issuewas issued in DecemberOctober 2012, and publicationwas published at the International Bureau inon February 28, 2013.

We also have filed for protection of various marks throughout the world and are committed to a significant long-term strategy to build and protect the MusclePharm brand globally. The “MusclePharm” mark is pending registration in 14 countries. The mark has been granted final trademark registration in threesix countries, and we believe the remaining registrations will be granted within the next several months.

The “MP” logo has been filed and registration granted in one country. The application for protection of the logo is expected to be filed in the near future in 26 additional countries. Going forward, we expect to seek trademark registration for our best-selling international products.

Competition

We compete with many companies engaged in selling nutritional supplements. The sports nutrition business is highly competitive. Most of our competitors have significantly more financial and human resources than we do, and have operating histories longer than ours. We seek to differentiate our products and marketing from our competitors based on our product quality, the use of sports celebrity endorsers and through our marketing program. Competition is based primarily on quality and assortment of products, marketing support, and availability of new products. Currently, our main competitors are three private companies: Optimum Nutrition, Inc., or Optimum, Iovate Health Sciences, Inc., or IHS, and Bio-Engineered Supplements and Nutrition, Inc., or BSN. Optimum is a wholly owned subsidiary of Glanbia Nutritionals, Inc., an international nutritional ingredients group. Optimum owns and operates two brands of nutritional supplements (Optimum Nutrition and American Body Building), providing a line of products across multiple categories. IHS is a nutritional supplement company that delivers a range of products to the nutritional marketplace. Headquartered in Oakville, Ontario, Canada, IHS’s line of products can be found in major retail stores and include such brands as Hydroxy-Cut™, Cell-Tech™, Six Star Nutrition™. BSN is also a sports nutrition leader whose top products include No-Explode™ and Syntha Six Protein™.

The retail market for nutritional supplements is characterized by a few dominant national companies, including GNC, Vitamin World, Vitamin Shoppe, and Great Earth Vitamin Stores. Others have a presence within local markets, such as Vitamin Cottage in Denver, Colorado. Four companies dominate the online channel—bodybuilding.com, vitamins.com (owned by Puritan’s Pride), GNC.com and vitaminshoppe.com, the latter two having retail sales locations as well.

Major competitors in the sports nutrition and weight-loss markets consist of companies such as EAS, Inc., Weider Nutrition International, Inc. and Twinlab Corporation, which dominate the market with such products as Myoplex (EAS), Body Shaper (Weider) and Ripped Fuel (Twinlab).

We also compete with a number of large direct selling firms selling nutritional, diet, health, personal care and environmental products, and numerous small competitors. The principal direct selling competitors are Amway Corporation, Nature’s Bounty, Inc., Sunrider Corporation, New Vision USA, Inc., Herbalife International of America, Inc., USANA, Inc., and Melaleuca, Inc.

We intend to compete by aggressively marketing our brand, emphasizing our relationships with professional athletes, and maximizing our relationships with those athletes, retail outlets and industry publications that align with our vision.

Our Manufacturers

We are committed to producing and selling highly efficacious products that are trusted for their quality and safety. To date, our products have been outsourced to a third party manufacturer where the products are manufactured in full compliance with the current good manufacturing practice, or cGMP, standards set by the U.S. Food and Drug Administration, or FDA.

We use four non-affiliated principal manufacturers for the components of our products, and multiple vendors for packaging and labeling. We have an agreement in place with our primary manufacturer. This agreement was designed to support our growth and ensure consistence in production and quality. Our primary manufacturer purchases all needed raw materials from suppliers. Additionally, our primary manufacturer is responsible for acquisition and storage of all product inventory (at both on and off-site facilities). We do not take title to our products until time of shipment to retailers. The three non-primary manufacturers are governed by purchase order terms and can be terminated at any time.

Our relationship with any of our manufactures may be terminated upon proper notice. We have established relationships with other manufacturers that we believe can satisfy our needs if our relationship with any manufacturer terminates.

Product Delivery

All of our products shipped out of the United States are shipped by our manufacturers directly to our retailers. Our manufacturers collect sales tax on products based upon the address of the consumer to whom products are sent regardless of how the order is placed. Products sold by MuscleCharm Canada are shipped from our inventory held in Canada. We collect sales tax on products when applicable.

Regulatory Matters

Government Regulation and Statutes – Product Regulation

Product Regulation

Domestic

The manufacture, packaging, labeling, advertising, promotion, distribution and sale of our products are subject to regulation by one or more federal agencies, including the FDA, Consumer Product Safety Commission, or CPSC, and the U.S. Department of Agriculture, or USDA. Advertising and other forms of promotion and methods of marketing are subject to regulation primarily by the U.S. Federal Trade Commission, or FTC, which regulates these activities under the Federal Trade Commission Act, or FTCA. The foregoing matters regarding our products are also regulated by various state and local agencies as well as those of each foreign country to which we distribute our products.

The Dietary Supplement Health and Education Act of 1994, or DSHEA, amended the Federal Food, Drug, and Cosmetic Act, or FFDC Act, to establish a new frameworkgoverning the composition, safety, labeling, manufacturing and marketing of dietary supplements. All of the products we market are regulated as dietary supplements under the FFDC Act.

Generally, under the FFDC Act, dietary ingredients that were marketed in the United States prior to October 15, 1994 may be used in dietary supplements without notifying the FDA. “New” dietary ingredients (i.e., dietary ingredients that were “not marketed in the United States before October 15, 1994”) must be the subject of a new dietary ingredient notification submitted to the FDA unless the ingredient has been “present in the food supply as an article used for food” without being “chemically altered”. A new dietary ingredient notification must provide the FDA with evidence of a “history of use or other evidence of safety” establishing that use of the dietary ingredient “will reasonably be expected to be safe”. A new dietary ingredient notification must be submitted to the FDA at least 75 days before it is initially marketed. The FDA may determine that a new dietary ingredient notification does not provide an adequate basis to conclude that the ingredient is reasonably expected to be safe. Such a determination could prevent the marketing of the dietary ingredient. The FDA recently issued draft guidance governing the notification for new dietary ingredients. Although FDA guidance is not mandatory, and companies are free to use an alternative approach if the approach satisfies the requirements of applicable laws and regulations, FDA guidance is a strong indication of the FDA’s “current thinking” on the topic discussed in the guidance, including its position on enforcement. At this time, it is difficult to determine whether the draft guidance, if finalized, would have a material impact on our operations. However, if the FDA were to enforce the applicable statutes and regulations in accordance with the draft guidance as written, this manner of enforcement could require us to incur additional expenses, which could be significant, and negatively impact our business in several ways, including, but not limited to, enjoining the manufacturing of our products until the FDA determines that we are in compliance and can resume manufacturing, which could increase our liability and reduce our growth prospects.

The Dietary Supplement Labeling Act of 2011, which was introduced in July 2011 (S1310), would amend the FFDC Act to, among other things, (i) require dietary supplement manufacturers to register the dietary supplements that they manufacture with the FDA (and provide a list of the ingredients in and copies of the labels and labeling of the supplements), (ii) mandate the FDA and the Institute of Medicine (a non-governmental, nonprofit organization that provides advice to the public and decision makers, such as the FDA, concerning health issues) to identify dietary ingredients that cause potentially serious adverse effects, (iii) require warning statements for dietary supplements containing potentially unsafe ingredients and (iv) require that the FDA define the term “conventional food”. If the bill is reintroduced and enacted, it could restrict the number of dietary supplements available for sale, increase our costs, liabilities and potential penalties associated with manufacturing and selling dietary supplements, and reduce our growth prospects.

The Dietary Supplement Safety Act (S3002) was introduced in February 2010 and would repeal the provision of DSHEA that permits the sale of all dietary ingredients sold in dietary supplements marketed in the United States prior to October 15, 1994, and instead permit the sale of only those dietary ingredients included on a list of Accepted Dietary Ingredients to be issued and maintained by the FDA. The bill also would allow the FDA to: impose a fine of twice the gross profits earned by a distributor on sales of any dietary supplement found to violate the law; require a distributor to submit a yearly report on all non-serious adverse event reports received during the year to the FDA; and allow the FDA to recall any dietary supplement it determines with “a reasonable probability” would cause serious adverse health consequences or is adulterated or misbranded. The bill also would require any dietary supplement distributor to register with the FDA and submit a list of the ingredients in and copies of the labels of its dietary supplements to the FDA and thereafter update such disclosures yearly and submit any new dietary supplement product labels to the FDA before marketing any dietary supplement product. If this bill is reintroduced and enacted, it could severely restrict the number of dietary supplements available for sale and increase our costs and potential penalties associated with selling dietary supplements.

The FDA or other agencies could take actions against products or product ingredients that in its determination present an unreasonable health risk to consumers that would make it illegal for us to sell such products. In addition, the FDA could issue consumer warnings with respect to the products or ingredients in such products at the point they are sold to end users. Such actions or warnings could be based on information received through FFDC Act-mandated reporting of serious adverse events. The FDA in recent years has applied these procedures to require that consumers be warned to stop using certain dietary supplements. For businesses that have been subjected to these regulatory actions, sales have been reduced and the businesses have been required to pay refunds for recalled products.

In general, we seek representations and warranties, indemnification and/or insurance from our vendors. However, even with adequate insurance and indemnification, any claims of non-compliance could significantly damage our reputation and consumer confidence in our products. In addition, the failure of such products to comply with applicable regulatory and legislative requirements could prevent us from marketing the products or require us to recall or remove such products from the market, which in certain cases could materially and adversely affect our business, financial condition and results of operations.

Under the current provisions of the FFDC Act, there are four categories of claims that pertain to the regulation of dietary supplements. First are health claims that describe the relationship between a nutrient or dietary ingredient and a disease or health related condition and can be made on the labeling of dietary supplements if supported by significant scientific agreement and authorized by the FDA in advance via notice and comment rulemaking. Second are nutrient content claims which describe the nutritional value of the product and may be made if defined by the FDA through notice and comment rulemaking and if one serving of the product meets the definition. Third are statements of nutritional support or product performance.The FFDC Act permits “statements of nutritional support” to be included in labeling for dietary supplements without FDA pre-market approval. These statements must be submitted to the FDA within 30 days of marketing and may describe how a particular dietary ingredient affects the structure, function or general well-being of the body, or the mechanism of action by which a dietary ingredient may affect body structure, function or well-being, but may not expressly or implicitly represent that a dietary supplement will diagnose, cure, mitigate, treat or prevent a disease. A company that uses a statement of nutritional support in labeling must possess scientific evidence substantiating that the statement is truthful and not misleading. The fourth category are drug claims, representations that a product is intended to diagnose, mitigate, treat, cure or prevent a disease, are prohibited from use in the labeling of dietary supplements, and we make no drug claims regarding our products.

We may make claims for our dietary supplement products regarding three of the four categories, that are statements of nutritional support, health claims and nutrient content claims when authorized by the FDA, or that otherwise are allowed by law. The FDA’s interpretation of what constitutes an acceptable statement of nutritional support may change in the future, thereby requiring that we revise our labeling. These regulatory activities include those discussed above concerning products marketed before October 15, 1994 or afterwards, and the requirements of 75 days advance notice to the FDA before marketing products containing new dietary ingredients. There is no assurance that the FDA will accept the evidence of safety for any new dietary ingredients that we may wish to market, and the FDA’s refusal to accept that evidence could prevent the marketing of the new dietary ingredients and dietary supplements containing a new dietary ingredient. If the FDA determines that a particular statement of nutritional support is an unacceptable drug claim, conventional food claim or an unauthorized version of a “health claim”, or, if the FDA determines that a particular claim is not adequately supported by existing scientific data or is false or misleading, we would be prevented from using the claim.

In addition, DSHEA provides that so-called “third-party literature”, e.g., a reprint of a peer-reviewed scientific publication linking a particular dietary ingredient with health benefits, may be used “in connection with the sale of a dietary supplement to consumers” without the literature being subject to regulation as labeling. The literature: (1) must not be false or misleading; (2) may not “promote” a particular manufacturer or brand of dietary supplement; (3) must present a balanced view of the available scientific information on the subject matter; (4) if displayed in an establishment, must be physically separate from the dietary supplements; and (5) should not have appended to it any information by sticker or any other method. If the literature fails to satisfy each of these requirements, we may be prevented from disseminating such literature with our products, and any dissemination could subject our product to regulatory action as an illegal drug.

Our dietary supplements must also comply with the Dietary Supplement and Nonprescription Drug Consumer Protection Act, which became effective on December 22, 2007. This law amends the FFDC Act to mandate that we report to the FDA any reports of serious adverse events that we receive. Under the law, an “adverse event” is any health-related event associated with the use of a dietary supplement that is adverse, and a “serious adverse event” is any adverse event that results in death, a life-threatening experience, inpatient hospitalization, a persistent or significant disability or incapacity, or a congenital anomaly or birth defect, or requires, based on reasonable medical judgment, a medical or surgical intervention to prevent one of these outcomes. Serious adverse event reports received through the address or phone number on the label of a dietary supplement, as well as all follow-up reports of new medical information received within one year after the initial report, must be submitted to the FDA no later than 15 business days after the report is received. The law also requires recordkeeping for reports of non-serious adverse events as well as serious adverse events for six years following the event, and these records are subject to FDA inspection.

In June 2007, pursuant to the authority granted by the FFDC Act as amended by DSHEA, the FDA published detailed current good manufacturing practice, or cGMP, regulations that govern the manufacturing, packaging, labeling and holding operations of dietary supplement manufacturers. The cGMP regulations, among other things, impose significant recordkeeping requirements on manufacturers. The cGMP requirements are in effect for all manufacturers, and the FDA is conducting inspections of dietary supplement manufacturers pursuant to these requirements. There remains considerable uncertainty with respect to the FDA’s interpretation of the regulations and their actual implementation in manufacturing facilities. The failure of a manufacturing facility to comply with the cGMP regulations renders products manufactured in such facility “adulterated”, and subjects such products and the manufacturer to a variety of potential FDA enforcement actions.

TheFDA has also announced its intention to promulgate new cGMPs specific to dietary supplements, to fully enforce DSHEA and monitor compliance with the Bioterrorism Act of 2002. We intend to comply with the new cGMPs once they are adopted. The new cGMPs, predicted to be finalized shortly, would be more detailed and stringent than the cGMPs that currently apply to dietary supplements and may, among other things, require dietary supplements to be prepared, packaged, produced and held in compliance with regulations similar to the cGMP regulations for drugs. There can be no assurance that, if the FDA adopts cGMP regulations for dietary supplements, we will be able to comply with the new regulations without incurring a substantial expense.

In addition, under the Food Safety Modernization Act, or FSMA, which was enacted on January 4, 2011, the manufacturing of dietary ingredients contained in dietary supplements will be subject to similar or even more burdensome manufacturing requirements, which will likely increase the costs of dietary ingredients and will subject suppliers of such ingredients to more rigorous inspections and enforcement. The FSMA will also require importers of food, including dietary supplements and dietary ingredients, to conduct verification activities to ensure that the food they might import meets applicable domestic requirements.

The FDA has broad authority to enforce the provisions of federal law applicable to dietary supplements, including powers to issue a public warning or notice of violation letter to a company, publicize information about illegal products, detain products intended for import, require the reporting of serious adverse events, require a recall of illegal or unsafe products from the market, and request the Department of Justice to initiate a seizure action, an injunction action or a criminal prosecution in the U.S. courts. The FSMA expands the reach and regulatory powers of the FDA with respect to the production and importation of food, including dietary supplements. The expanded reach and regulatory powers include the FDA’s ability to order mandatory recalls, administratively detain domestic products, require certification of compliance with domestic requirements for imported foods associated with safety issues and administratively revoke manufacturing facility registrations, effectively enjoining manufacturing of dietary ingredients and dietary supplements without judicial process. The regulation of dietary supplements may increase or become more restrictive in the future.

Our failure to comply with applicable FDA regulatory requirements could result in, among other things, injunctions, product withdrawals, recalls, product seizures, fines and criminal prosecutions.

Our advertising of dietary supplement products is subject to regulation by the FTC under the FTCA. Section 5 of the FTCA empowers the FTC to prohibit unfair methods of competition and unfair or deceptive acts or practices in or affecting commerce. Section 12 of the FTCA provides that the dissemination of any false advertisement for the purpose of inducing, directly or indirectly, the purchase of drugs or foods, which would include dietary supplements, is an unfair or deceptive act or practice. Additionally, under the FTC’s Substantiation Doctrine, an advertiser is required to have a “reasonable basis” for all objective product claims before the claims are made. Failure to adequately substantiate claims may also be considered an unfair or deceptive practice. Pursuant to this FTC requirement, we are required to have adequate substantiation for all material advertising claims made for our products.

On November 18, 1998, the FTC issued “Dietary Supplements: An Advertising Guide for Industry.” This guide provides marketers of dietary supplements with guidelines for applying FTC law to dietary supplement advertising and reiterates and explains the FTC’s “reasonable basis” determination. It includes examples of the principles that should be used when interpreting and substantiating dietary supplement advertising. Although the guide provides additional explanation, it does not substantively change the FTC’s existing policy that all supplement marketers have an obligation to ensure that claims are presented truthfully and to verify that such claims are adequately substantiated.

The FTC has a variety of processes and remedies available to it for enforcement, both administratively and judicially, including compulsory process, cease and desist orders and injunctions. FTC enforcement can result in orders requiring, among other things, limits on advertising, corrective advertising, consumer redress, divestiture of assets, rescission of contracts and such other relief as may be deemed necessary. Any violation could have a material adverse effect on our business, financial condition and results of operations.

As a result of our efforts to comply with applicable statutes and regulations in the United States and elsewhere, we have from time to time reformulated, eliminated or relabeled certain of our products and revised certain advertising claims. We cannot predict the nature of any future laws, regulations, interpretations or applications, nor can we determine what effect additional governmental regulations or administrative orders, when and if promulgated, would have on our business in the future. They could, however, require the reformulation of certain products to meet new standards, the recall or discontinuance of certain products not capable of reformulation, additional record keeping, expanded documentation of the properties of certain products, expanded or different labeling, and/or scientific substantiation. Any or all of such requirements could have a material adverse effect on our business, financial condition and results of operations.

Advertising and labeling for dietary supplements and conventional foods are also regulated by state, county and other local governmental authorities. Some states also permit these laws to be enforced by private attorney generals. These private attorney generals may seek relief for consumers, seek class action certifications, seek class-wide damages, seek class-wide refunds and product recalls of products sold by us. There can be no assurance that state and local authorities will not commence regulatory action, which could restrict the permissible scope of our product advertising claims, or products that can be sold in the future.

Foreign

Our products which we sell or may make plans to sell in foreign countries are also subject to regulation under various national, local and international laws that include provisions governing, among other things, the formulation, manufacturing, packaging, labeling, advertising and distribution of dietary supplements and over-the-counter drugs. These regulations may prevent or delay entry into the market or prevent or delay the introduction, or require the reformulation, of certain of our products. Compliance with such foreign governmental regulations is generally the responsibility of our distributors for those countries. These distributors are independent contractors over whom we have limited control.

Possible New Legislation or Regulation

Legislation may be introduced which, if passed, would impose substantial new regulatory requirements on dietary supplements. For example, although not yet reintroduced in this session of Congress, bills have been repeatedly proposed in past sessions of Congress which would subject the dietary ingredient dehydroepiandrosterone, or DHEA, to the requirements of the Controlled Substances Act, which would prevent the sale of products containing DHEA. In March 2009, the General Accounting Office, or GAO, issued a report that made four recommendations to enhance the FDA’s oversight of dietary supplements. The GAO recommended that the Secretary of the Department of Health and Human Services direct the Commissioner of the FDA to: (1) request authority to require dietary supplement companies to identify themselves as a dietary supplement company and update this information annually, provide a list of all dietary supplement products they sell and a copy of the labels and update this information annually, and report all adverse events related to dietary supplements, not just serious adverse events; (2) issue guidance to clarify when an ingredient is considered a new dietary ingredient, the evidence needed to document the safety of new dietary ingredients, and appropriate methods for establishing ingredient identity; (3) provide guidance to industry to clarify when products should be marketed as either dietary supplements or conventional foods formulated with added dietary ingredients; and (4) coordinate with stakeholder groups involved in consumer outreach to identify additional mechanisms for educating consumers about the safety, efficacy, and labeling of dietary supplements, implement these mechanisms, andassess their effectiveness. These recommendations could lead to increased regulation by the FDA or future legislation concerning dietary supplements.

We cannot determine what effect additional domestic or international governmental legislation, regulations, or administrative orders, when and if promulgated, would have on our business in the future. New legislation or regulations may require the reformulation of certain products to meet new standards, require the recall or discontinuance of certain products not capable of reformulation, impose additional record keeping or require expanded documentation of the properties of certain products, expanded or different labeling or scientific substantiation.

Employees

We believe that our success will depend significantly on our ability to identify, attract, and retain capable employees. As of October 25, 2012,June 11, 2013, we had 4547 full time employees. Our employees are not represented by any collective bargaining unit, and we believe our relations with our employees are good.
