Exhibit 31.1
                                                                  ------------

                                 CERTIFICATION
                                 -------------

I, William P. Horgan, certify that:

     1. I have reviewed this quarterly  report on Form 10-QSB of Human Pheromone
Sciences, Inc.;

     2. Based on my knowledge, this quarterly report does not contain any untrue
statement of a material fact or omit to state a material fact  necessary to make
the statements made, in light of the  circumstances  under which such statements
were made, not misleading with respect to the period covered by this report;

     3. Based on my knowledge,  the financial  statements,  and other  financial
information  included in this quarterly  report,  fairly present in all material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this report;

     4. The registrant's  other certifying  officer(s) and I are responsible for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

          a) Designed such disclosure  controls and  procedures,  or caused such
     disclosure controls and procedures to be designed under our supervision, to
     ensure that material  information  relating to the registrant is made known
     to us by others within those  entities,  particularly  during the period in
     which this report is being prepared;

          b) Evaluated the effectiveness of the registrant's disclosure controls
     and  procedures  and  presented  in this report our  conclusions  about the
     effectiveness of disclosure  controls and procedures,  as of the end of the
     period covered by this report based on such evaluation; and

          c) Disclosed in this report any changes in the  registrant's  internal
     control over financial reporting that occurred during the registrant's most
     recent fiscal quarter that has materially affected, or is reasonably likely
     to materially  affect,  the  registrant's  internal  control over financial
     reporting; and

     5. The registrant's other certifying officer(s) and I have disclosed, based
on our most recent evaluation of internal control over financial  reporting,  to
the  registrant's  auditors  and the audit  committee of  registrant's  board of
directors (or persons performing the equivalent function):

          a) All significant  deficiencies and material weaknesses in the design
     or  operation  of  internal  control  over  financial  reporting  which are
     reasonably  likely to adversely affect the registrant's  ability to record,
     process, summarize and report financial information; and

          b) Any fraud,  whether or not material,  that  involves  management or
     other employees who have a significant  role in the  registrant's  internal
     control over financial reporting.
