Re: Juan Manuel Marquez looking like a beast . . .
How many "experts" on this thread have actually trained at a serious level themselves?
The transformation in JMM is possible without PEDs. I'm not a professional athlete committed to my sport 24/7 and I could do it with strict diet and a precise training schedule.
In terms of boxers, PEDs are a shortcut but you can get to the same place physically with hard graft and discipline. Now competition bodybuilders who freak up is a different topic all together.
