Dennis was touted as a drug-free bodybuilder in the Weider mags in the late 70's-early 80's. Steve Davis was also said to be drug-free, which I could believe because well, look at the guy.
Rick Wayne once referred to Steve as a "lion attempting to imitate a gazelle" in reference to his going for the ripped, symmetrical Zane-like look over attaining the mass he should have carried on his frame to be competitive.
But Dennis, drug-free? Anyone "in the know" care to comment on this?
