You know, that is a really good question. I like to call it OTC bodybuilding. I guess it cover all substances non hormonal in nature. Natty test boosters are legal in tested comps though. ????? I don't know for sure.
The really funny thing is that the FDA could possibly make all bodybuiders "enhanced". That is if we let Congress be our morale compass.
I guess in short it probably is, for the sake of this board, AAS and Prohormone free.
