oh, yes, with better , tolerance comes better response, i meant.
the affording stuff point you make is bit moot, often you have people who can afford gear better than pros in the gyms.
however, the gymrats often dont have the same good sources, they run ugl steroids, pros will prefer from harmacy, same with gh.
besides that, pros will have more time to train and eat properly and thus, have better results.
and something i think is very important factor,is the pros get more rest time, while gymrats get drained from energy at their daily jobs.
the difference is an accumulation of many small factors, not just the dosage.
if it was just dosage issue, then every rich boy should dwarf pros.
How many rich boys are wasting their time bodybuilding though

But there is one, a South-African guy, supposedly very rich and he is pro-size. Can't remember his name. Guy something?
Still, let's not be fooled, it's all drugs and always has been. The winners of true natural contests (if they exist), yes they are probably genetically superior.
