I got derma-gain from them... I did what that other dude suggested... looked up derma-gain on yahoo, and bought it from the cheapest provider...
It seemed to work well for me... but I wouldn't do it again, the money that I paid (like $50) wasn't worth the differnce to me!!!
So far Creatine is the only sup. that I've ever used that I've actually seen difference with... (I know this is water weight, but I see difference in my workouts as well... this was not the case w/ derma-gain, with dg I mainly saw recovery improvements)
