IGF-1, in a lot of ways is like Human Growth Hormone (HGH), or GH in short, is certainly an effective fat burner and anabolic agent, and is a protein secreted by the pituitary. Once secreted, it has the ability to influence various cells in the body to increase in number and size, as well as having the ability to enhance the movement of amino acids through cell membranes- thereby increasing the rate at which the cells can convert those molecules to usable proteins. It also causes cells to preferentially burn fat in lieu of carbohydrates.
