Very onest interview with Rony Rockel. (this is not a exact translation but basicly what he says..)
Says no Pro would ever admid what he realy takes..
But 13 grams per week would be a very low dose cycle for Yates or Coleman. Back in the day they where doing crazy cycles.. (he isnt telling everything but it seems he knows what they where taking and to what extend)
Rockel was shocked after seing Yates for the first time, he thought it was impossible to weight this much and to be this big. Yates only did ten years of professional bodybuilding, because his body could not take more punishment. He saw him again later and Yates lost almost everything within a year, even his back. (was unrecognizable after one year off)
Rockel says: if they are bigger and harder, they take more.. there are no genetic exceptions to this rule..
atleast he has never seen a genetic outlier. He has never seen a good natural in his life.. (muscular and hard)
He heavily regrets that he didn't took enough steroids in his career, in the beginning he didn't knew any better (only did Dianabol, 800mg Propionat, Winstrol, 2007 Australien GP) and later because he was low on money\scared and developed Diabetes. He did some heavy cycles later but it wasn't enough in his opinion.
He has seen the stack's of some big guys through a popular trainer and 1.2 grams of Tren a week was standard. Says he only did barely a third of that. (later in career)
If he could start all over again he would go all in from the beginning..
He also says that this is only his opinion and what he knows about bodybuilding. (one of the most active Pro's, knows alot of people\Trainers and programs). Rockel says when the Pro's reveal theire low dose stack's in interviews they have a hard time to hold back their own laughter..
Also says alot of competitions are rigged and Joe Weider's plan was to make Günter Schlierkamp Mr. Olympia. :O
