What is IGF-1 and how does it relate to the Human Growth Hormones released by using GHR 15?
IGF- 1 (Insulin Growth Factor) also known as Somatromedin C, is the most important growth factor that comes from the liver. It is IGF-1, rather than growth hormone itself, that is used as a measurement of how much growth hormone is being secreted by the body. If you wanted to measure to see if GHR 15 was effective, you would get your IGF- I levels tested before and after with a simple blood test.
