I'll tell you straight - unless you turn out to be some type of hyper responder to steroids.. I dont see a pro caliber build happening for you.
which isn't such a bad thing really... very few people have the genetics for that anyway.
Yes, i pretty much realise that i have maybe a 1 in a 1,000,000 chance of turning pro. That being said, that doesn't discourage me. I feel my size in relation to age/height/training experience is ok so i'll try my best.
