That is that stuff that is suppost to be a steroid-like supplement; claiming that it can create steroid-like growth without dealing with the illegality of real gear. Well, I can say that I have never used the stuff, but from what I have heard, the shit isn't all it is cracked up to be. More often than not, you might grow a miniscule amount, but still get some sides. There are plenty of companies claiming to have "bridged the gap" between steroids and their steroid-like stuff, but there is still no comparison to real gear. Check out anabolicreview.com and click on steroid alternatives if you want more info on steroid precursors. My advice would be to do some more research, and if something sounds to good to be true, then it probably is. Good luck and happy lifting!
