why don't you just save the gh for when you are on cycle ? when you peak on cycle, hit the gh high dose for a month of whatever you got and be finished with it.
Thats what I would do, and will do for my next cycle. But i'm not on pharm grade hgh.
Anyway, I think you will get the most on if if you run it during AAS cycle, say 4-5 weeks in, and hit it high.
