How the hell would you know, were you taking Anabolic Androgenic Steroids (AAS) 30 years ago? The author didn't even mention dosages used during the 70's.
A truly intelligent person would understand that everything including bodybuilding-AAS use, must evolve. These guys understood that Anabolic Androgenic Steroids (AAS) are powerful drugs that must have potentially negative side effects. Unfortunately in the 70's there was virtually no factual knowledge of the side effects. Dan Duchaine was the first to recommend the use of Nolvadex to combat gyno, sometime in the late 80's, and that was just based on theory.
Bodybuilders in general during the 70's relied much more on heavy training than the newbies of today. Today's newbies think it's all about the drugs, and they train like pussies!
