Let me shed a little light on Musclemania.com. I am a Musclemania pro, and have been for the last 5 years. The top 5(in each category) do get tested...but as of recently they have tightened things up by testing before the show to make sure those that fail, will not make it to the stage. Testing is hard to do, so promoters have to change things up to keep the athletes off balance. In the past year alone, at least 12 bodybuilders have failed their drug test and are suspended(to include several Pro's). Everbody(Intelligent) knows that drug testing does not keep the cheaters out..at best...it makes it another obstacle.
Many past and preent bodybuilding stars have started in Musclemania. Some have chosen to take the "other" route by heading to NPC then IFBB(Current NPC-IFBB Stars-Stan McQuay, Brandon Curry, Mark Alvisi, Sami Smith, Dan Decker etc)...while other have stayed natural(Skip Lacour, Ade Rai, Delino Dixon, Tito Raymond, Morris Mendez, Ulysses etc). These type of bodybuilders are the one's that get the most magazine covers in comparison to IFBB pro's.
