Is that even possible without using juice?
of course it is. look at ronnie coleman, the only supplements he uses is BSN, yeaah right budddayyy. Jay Cutler only uses supplements too! This should be a no brainer, duh! Keep telling yourself you can get that big naturally.
Possible? Maybe, for like .000001% of the population, those with a Myostatin mutation. Probable? No, absolutely not.
And if someone did have the freakish genetic makeup to accomplish that level of muscularity, you can bet that they wouldn’t be asking the question. They’d have know all their life that they were different from everyone around them and would have exhibited almost super human levels of strength and most likely athleticism as well.
