HGH Riptropin 10IU is a highly effective bodybuilding and strength enhancing supplement. Most often Kigtropin is used in cycles. It may be three months on and then off for one month. It is usually injected daily using 4 to 5 IUs/injection. Most users experience increased muscle density and muscle mass and an increase in energy. In addition, HGH users do not experience the increased aggression that is normally induced by anabolic steroid use. Kigtropin can also significantly reduce the amount of time it takes to recover from injuries such as muscles or tendon tears. Most physicians will tell you that HGH certainly has some therapeutic benefits.
