6.       We note your response to our prior comment 14 and reissue. Given the
early stage of
         these products, these claims appear speculative. Please provide
context and support to
         explain your basis for the claims that "natural compounds used in the
Linebacker platform
         have demonstrated strong potential in treating and preventing a range
of diseases . . ." and
         that "use of Laetose in a daily diet, compared to sugar, could result
in 30% less sugar
         consumption and lower glycemic index/load." Please also describe any
discovery
         activities you have conducted for these and your other product
candidates. To the extent
         that these claims are the opinions or belief of management, please
revise your statements
         to clearly characterize them as such and provide appropriate support
for these
         opinions/beliefs.
