I've only run GH once for approx 7-8 months and at a low dose 3-4ius ed and I will say I felt and looked great. I slept like a baby, trained half assed for like 6 of those months and ate whateverthefuck I wanted and I still had abs and stayed lean. I wasnt using it for the sake of gaining any mass. Honestly, I just wanted to try it, for the experience, and I am convinced that in a few years (I'm only 40 now) I will definitely benefit from running it year round
