this
that documentary was about a guy who had friends and his own brother on them, and he was trying to show the negatives NOT positive sides. the guys who do take shit and compete weather it be in body building or powerlifting is understood but does not mean it good healthy or accepted. NO ONE i kno who competes in these EVER brags or says that they are good. they know they arent but they use the to accel at thier sport. no one on this site does anything with them but brag about them and try to be big and strong. ive been around them for ever and tried it my self years ago when i was young and stupid and all i have to say is they are bad for you! the only guys on here saying they are good are the ones who dont want thier to be anything wrong with it and they also dont do shit with them. sorry no hard feelings fellaz
