There seems to be two kinds of group and then the ones in between...
group A - thinks it's all hard work, training, muscletech supps, pro size can be acheived natural
group B - the "GH15" group, pump any skinny kid with drugs and turn pro easily and possibly win the olympia. Genetics don't matter for the most part...
Then the ones in between group C - knows drugs is a big part, the half ass training shows you that it is indeed genetics cause these guys grow no matter what from response to training and drugs, they can tolerate high dosages for the time being competiting....
