"WebThe insulin-like growth factor 1 (IGF-1) is the main mediator of the human growth hormone (HGH). More specifically, IGF-1 mediates its anabolic effects such as growth, development, and recovery in each of your tissues. Together, the two hormones form the so-called GH/IGF-1 axis which plays a major role at every age. " - Igf-1 lc/ms
