I have a friend who is 60 years old. He has a bad back and is wanting to run some HGH. He is hoping that it will help him to feel better and possibly help his back issues. Hes not overweight,in pretty good shape for his age, not looking to get huge. He is looking to purchase Kefei from HGHPOWER. Will taking the hgh by itself, 2 or 3 IU per day, benefit his cause?
