All Drugs 
Don't forget genetic response to drugs.
Yes, at the end of the day, regardless of how most "competitors" look, they achieve very little without the use of heavy anabolics. Sad, but true. Show me one "pro" who put on 40lbs of muscle, before touching any drug? What, Ronnie Coleman...then who?
People can spin it any way they'd like to, at the end of the day, they know where their gains lie. Needles and pills baby.
However, many can take the same amount of gear and look nothing close to this though, so very true. Does this mean I respect it more, of course not.
