Don't know about the all muscle part
When I started I was 165 soaking wet and 19% BF. Yesterday I was 270 and still have the tops of my abs. Usually that's about 15% for me.
Beer and porks rinds!! Not far from the truth for the first couple of years.
As far as cycles go mostly test and deca. Even for contest prep.
Used alot of Borresson's theories over the last year. Great gains but very very taxing on the body.
I would be glad to go over some of the cycles in e-mails if anyone wants to know.
Thanks for the Welcome
