I would say...pound for pound....Michael Francois was a better body builder than Bob
Look at him now
Mike won the Arnold and was in his prime a better rated pro than Bob ever was, no question.
However, Mike F had some major intestinal issues , was quite ill and required extensive surgery, etc.
You really can't compare that to some bodybuilder that eases back on the juice over time.
Do drugs make a difference? Doah...of course they do. But they are NOT the end all be all for building a great physique, they do tend to make a great physique look freakish and that is something I am NOT for.
Pick out 100 rugged , strong , age 20's guys from various gyms. Have them train hard for a few years, diet and take a good helping of juice and see what happens. Sure they will get a lot bigger and more muscular but how many will look like Dexter, Jay or Heath? No too many. THAT is my point.
So long as the magic cycle to the pros exist, the juice will get sold on the blackmarket and the legal magic supplements will be sold by the millions. It is a myth and something I don't buy into.
