I've been taking 2 i.u. of somatropin for two months. Since this is my first time with GH i figured I'd start light and work my way up. the only side i have is pain in the joints of my hands. my hands feel slightly swollen, like a tight feeling when a clinch them. aside from the pain in each joint of my fingers, there are no other sides. I know that I probably won't get sides at such a low dose, but i figured I'd pass it along. As far as benefits, I have not noticed much yet. A little leaner around the mid section, but not much. my diet is not that dialed in, so that is more my fault. I think I'm going to up my dose to 3 i.u daily. I'm also running this along with TRT.
