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