does any 1 on this site use roid for performance instead of just bodybuilding/sculpturing, you here of sprinters, boxers& mma's (which have to be in weight classes so they cant put on extra weight) using all the time, ive noticed most ppl on here just want to get heavier, but is there any 1 that takes gear just for perfomance eg: speed, endurance and power(not lifting but explosive) ????
