Rusty is getting grumpy, so lets just go with some facts. In studies of young adult male weight trainers, increases were found in muscle volume (~6-8%) and lean body mass (~11%). Exercise capacity was elevated in such patients (~12%), but strength was either not changed or mildly increased by about 8% (Jorgensen 1989, Salomon 1989).
I don't know about you, but an 11% improvement in lean body mass impresses me. Sounds to me like this is the stat that interests you the most. These studies were with GH used alone.....no gear. For lean muscle growth in addition to the above benefits, add in some steroids. Prop, eq, tren and winstrol is an awesome cutting stack with GH.
Personally, I use heavy test and insulin with my GH, and finish up with tren, eq, winstrol for maximum size and leanness.
I won't judge you on your age, but I can tell you, hGH is extremely effective for old farts like me.
At your age, you will be at the peak of your own natural production, and would not need big doses of exogenous GH. Even just 2iu a day would more than double your own natural production.
