Scientific Evidence

Isatori makes many claims about these ingredients, but none that can stand up to any credible scientific proof, meaning that they were put through double-blinded, placebo-controlled studies that provided reliable results that were free of partiality. While it may be true that this product is legal and drug-free, it is difficult to conclude that this product is effective since there is not enough research on these ingredients to prove otherwise.

Consumer Feedback

“I used this product, and can’t say too much about it, it claims to send your T through the roof! Not for me. It did make me a little edgy. But nothing like the claims on the site or in the books. Maybe good for older men looking to boost libido.”

--BJ on August 18, 2007

“…after 14 days on I must say this product has definitely made a difference. I have added to my bench press, gotten noticeably bigger and defined (as commented on by my wife), and have seen extra energy. Definitely added something to the sex drive, although I was not having issues in this department.”
