Well I'm from Bulgaria and I know the guy...He was an IFBB world and european champ in 2004...75kg class...this video is from 2005 local show in Bulgaria.
He was a pro for a while and placed a very good 9th at his debute at the Europa super show 2005 - the first pro win of Branch Warren.
Here's some pics from that show:
The current best bulgarian bodybuilder is the new IFBB superheavyweight champion Dimitar Dimitrov(6'1,265lbs):
naw man no way hes 170, my buddy is as short as it can get(literally he cant be any shorter) and hes a pretty big dude already but nothing like that and he weighs about 170-175, and hes dry as shit and super low bodyfat, hes not competing and his glutes separate from his hams and everything, no way this guy can have that much size and be that short
