How many bodybuilders do u know? how many of em haven't used???? Actually, when u start training 4 it most gym "instructors" encourage u to use em... And, ok it can be speculation but, most of em inject taht stuff... Know a faster method to gain more then 8kg of muscle in a hormonal cycle (30 days), not 4 a thin complexion guy... and looking at this guy wrists and ankles (maybe is a light effect) i can guess he wasn't of "strong" complexion... Anyways i cannot assure anything, but it's a common method between bodybuilders...
