I saw the article where he mentioned his dosage. You’d be surprised how many past pros lied about their dosages.
From Nelson Montana, the author of “The Bodybuilding Truth”:
“I have fairly recently trained down in Florida with top pro of the 70’s and early 80’s CASEY VIATOR.
I asked him directly about steroid use in the 70’s and this is what he had to say… and I quote…
‘Don’t let anyone fool you about our low doses. We were just as reckless with steroid use as they are today.’
I asked him when the big doses started…
‘The big doses started around 1974 and yes we were all right on top of it". Yes we ALL used GH back then and it was from real cadavers. The GH we all used was called CRESCORMIN and nobody was going to morgues to get it.’
I wanted an example and I told him about what I heard my mentor, and his friend and former training partner, Mike Mentzer used…only 400 of deca/week and 30 of d-bol/day.
CASEY LAUGHED and then said this…
‘Mentzer used up to 2.5 grams of deca a week, God knows how much primobolin acetate, along with d-bol and growth, so as I said don’t be fooled about our low doses as we were just as reckless as theses guys are today.’”
Mike died at 49. That’s absurdly young - we may not know exactly what he took but I’d lean far more towards what Casey was laughing about in this interview. 400mg of deca ain’t killing someone in their 40s. They were all juiced up back then too.
