It's the combo for sure. Hgh and insulin feed off eachother. Insulin just amplifies the effects even that much more. Plus it rapidly converts straight to fat if used wrong.
Personally if I wanted to walk around looking like I ate a turtle I'd rather at least be strong as shit and do strongman or something.
Who knows. Bodybuilding is transforming faster than ever and we may see the old days come back. Personally I'm a fan of the 80's and 90's pretty much right in the middle of the old school look at the modern day.
