Well you didn't just buy it you, busted your ass I'm sure. You just don't have the typical giant head and out of proportion arms that people I know who use PEDs typically get. The most popular is Tren that I see currently, HGH is always around of course. A lot of meat heads at work sell them.
Good on you though to not ruin your body with them, some people just wont stop. You start to look ridiculous with tren IMO, you get so big so fast it starts to look weird, especially if you are short.
I quit lifting perosnally due to my crohns disease melting my joints, I blew my acl and mcl just walking at work so lifting is no good. In the end agree to disagree but great Job on the physique either way
