What IGF-1 and how does it relate to the Human Growth Hormone released by using ghr15?
IGF-1 (also known as somatromedin C) is the most important growth factor comes from the liver. It is IGF-1, rather than growth hormone itself, that is used as a measurement of how much hormone is being secreted by the body. If you wanted a measure to see if GHR15 was effective, you would get your IGH-1 levels tested before and after with a simple blood test.
