I was watching yesterday a show on bodybuilding by the discovery channel that I taped about 8 months ago. First off let me say this is the best documentary on bodybuilding I have seen thus far it has interviews with two pros that I have seen on flex a lot but I cannot remember there names. But the two guys they followed were "natural body builders" now not as much as these guys but the guys at the shows who were "natural" were HUGE, and I honestly cannot see these guys being natural, maybe they were natural for the week coming into the show, but can't they just take short lasting steroids like winny or other orals or water based steroids? Does this happen or are these guys actually natural?
