What does it do? Or supposed to do? Have you heard of anyone making massive gains on it? My guess is probably no. The major supplement companies are always trying to get your dollar coming out with the latest greatest supplement that is "just like steroids" but legal. My guess is to stay away from it, save your money. Buy legit products that you know work...I.e.protein, glutamine, creatine. Good luck. Don't fall into the "supplement of the month club". It is quite expensive to join.
