ANyone who claims that bodybuilding success is mostly about drugs and your genetic response to them is an IDIOT.
That is as silly as saying that drugs don't work at all or make any difference in the size of a bodybuilder.
Obviously drugs enhance any physique and make a difference . BUT to me , diet discipline , muscle shape, separation , training intensity, avoiding injury, peaking , etc are all key factors . To act like drugs is the vast majority of success is ignornant and stupid.
