I`ve got one for you Disgusted.
Damn you.

Me thinks I am being set up. OK first off conditioning easily done without drugs. Size wise upper body I would say yes can be done natty. Most people would look at this guys legs and say no way, but when I was younger people always commented about my thighs and back long before I ever dabbled. I was genetically blessed in that area. I have seen newbies come into the gym with some very freaky arms, arms that appeared way bigger than they really were because of their shape and density. So is this guy natty? I have no idea, a better question to ask would be is this physique attainable with out drug use? My answer is yes.
