i really wish you would not speculate. Tren was not around then.
Also, Arnie never had gyno, or really any other high estro signs for that matter. 160mgs of dbol a day? I think not. In fact, Franco is the only 70's guy that I have ever seen with gyno......and that was in the 80's. You can see pics today with pretty much every top pro having gyno sometime or another in their carreer. I don't think the pros have become genetically resistant to gyno in the last 30 years, do you?
I think some of you want to justify why your looks cant compared to them by simply saying how much more drugs they use. Not dissimilar to what fat lards do to the rest of us bodybuilders when they are jealous. Some of you 1.5 + gramers dont want to admit that there is a very good chance you are taking more drugs than Sergio Olivia ever did, but don't look even close to him.
Rememer, these guys have fantastic genetics, they worked out like it was their 9-5 job (which it was), and most trained every muscle at least 3 times a week. How many do that now? None. How many can do that now and not overtrain? Not very many.
Sure they used drugs. It was probably more than they admit to, but it didnt look like today's pros.
