Dude it is not about back stabbers. There is an unwritten code of ethics so to speak in bodybuilding. We never talk about another person or bad mouth him or her regarding AAS. In my experiences, most of us follow it, a select few do not.
Likewise, we seldom openly discuss sources, methods, or any subject that may implicate us in illegal behavior. There are people in my gym whom I compete against and really can't stand(who also sell AAS), but I never bad mouth them regarding AAS. I might crack on his legs but never, never, never the AAS.
