Ask yourself how many natural trainers are there that eat well and train hard for years on end (sometimes decades on end) and don't look even remotely close to what O'Hearn does. Then ask yourself how many men actually abuse steroids and PED's and still don't even remotely look close to O'Hearn. If countless others taking copious amounts of hormones still can't even remotely come close to O'Hearn, how is it O'Hearn has achieved naturally what so many drug abusers can not.
And the look is undeniably the drug look, the vascularity, the 3D Deltoids and the obvious exaggerated amount of lean muscle mass.

on the flip side, to be objective, why is it so unbelievable that occassionally one or two freaks appear?
o'hearn has nothing of the tell tale signs of a drug abuser, and his physique hasnt changed very much for years.
how many weight trainers train strictly and eat strict for years on end and dont get injured or end up abusing rec drugs?
what amazes me is that GB has so many people on it that immediately rule out the possibility of achieving mike's look.
this look that he has doesnt win him regional contests when up against obvious drug users, and he doesnt have the bunched up, bloated appearance, with speckled skin and distended stomach that so many others do.
yet he still doesnt suddenly get massive.
the more you look at it from an objective standpoint, the more evidence there is that he isnt a user.
that is, once you can get past the bias that you think it cant be done without gear.
that mentality was prevalent here at GB when GH15 was around. try hanging out with some totally natural guys who eat well and train hard and have good genetics and you'll be impressed how much size and shape is possible.
size, bfat and shape are NOT evidence of drug abuse unless they are accompanied by things like bitch tits, aggressive attitude, poor skin, palumboism, guts, abnormal skeletal size, large changes in bweight, water bloat, site scarring, admittance of use, more than minimal new muscle tissue each year. also, hair loss CAN be, but male hair loss is common so its not a smoking gun.
so whilst it is true that some guys who are admitted drug users also dont have many indicators, almost all of them had some of the indicators at one time or more.
the fact is that those who say he is a user, dont know. all it shows is that the person believes that what he has achieved isnt possible. and thats a reflection on themselves.
