Bro, Reg is lifetime natural - he never used anything. He's been telling guys to stay away from drugs for at least the 40 years that I've been reading the mags.
I dont know about Reg for sure, but how can you guys really trust what any bodybuilder says. If they lie now, why woudn't they lie then.
They had more reason to lie back then. The culture was more puritanical. Any kind of drug use for a public figure would have them banned and shunned for life. It makes sense that they would hide it even more.
