I wonder about the gyno too. Maybe it is just genetics after all. My father never had acne in his entire life, and started shaving at 15 yrs old he said. I started shaving only at 19 and have a little acne. Ever since i became interested in bodybuilding, i have always kept a few pictures i remember, studied them, and in my opinion this one below is a time when he was going heavy on the Dianabol or Test, I usually think claims off ''he's on so so '' is rediculous, you can't really tell what gear someone is using. But in this pic he definitely looks to be on either Dbol or Testosterone, because in those day i imagine you just took whatever it was, and that was it. No fancy ancillaries or super strong aromatase inhibitors, and/or didnt kno the significance of them at the time .. they took the full brunt of the compound, excess estrogen, water retention, etc, but probably figured out that there was certain compounds which leaned them up for contest, without the crazy strength gains and excess baggage. I suppose a lot of it was very anecdotal?

I bet he could of put up 380 or maybe 400 for a few on bench at that size
There are literally thousands of arnolds pic's and see rare ones every so often i havent seen before...i like looking at them in between training days, really good motivation! usually each one tells a story
