He always was big. A few years ago he started doing some fights in the WWF and at the same time seems like he jumped into bodybuilding again. He looks great.
The drug policy was pertaining to well...drugs. Steroids are not drugs and steroids in the WWE only gets better ratings because you dont want small ass guys in there, doesnt make for good entertainment. Which brings me to my next point, its purely entertainment and not a sport so why would they test for AAS?
