Most guys on here will believe in whatever they want to believe to make themselves feel better about their own shitty genetics.
How about taking into consideration.
Does he for size (6-10times a day), do you honestly think if he went down to 2 meals a day he would not shrink.
Does he train for size?
You honestly believe if you MMA fighter or boxer stops his training and starts smoking and eating bad everyday for months on that they would not change?
I'm not saying drugs did not play huge roll on how he looked as a pro but at the same time no amount of drugs will make you look like he did without day to day hard training and eating a lot.
