True Adonis first of all I belive you just jealous that you will never look like a pro. You do have serious issues and obsession about drugs.
I think the fact that you know that naturally you will never even look like average national cometitor makes you a very sad, sad person who tries his best to make himself belive that "it's all about drugs"
Well whatever makes you feel good I guess.
Now to the subject. Besides the fact that steroids exist in all professional sports and it's safe to say that all athletes use performance enhancers to some extent, it's still obvious that to be a bodybuilder you must have genetics to respond to training, nutrition and yes drugs.
Even without the drugs the top Olympia competitors with proper training, nutrition, rest would look way better than average Joe (and that includes you too). The drugs simply enhance the work, diet, dedication and genetics.
As for who keeps training after their career is over that is individual decision.
Will you ever start a threat not related to drugs?
