Isn't that made by the company that Marcus Ruhl is under contract w/ now?
I can tell you this though. I don't think I've ever taken a supplement that made me grow. I like ZMA to help me sleep, glutamine for dieting, multi's, Vitamin C, ALA, minerals, and a host of other stuff. I just don't see why spend $80 on a pill like that. Pills don't make you grow, legal pills anyway. FOOD!!!
