IGF-HGH

Growth hormone (GH), also known as somatotropin or human growth hormone (hGH or HGH), is a peptide hormone (substances made of amino acids) that stimulates muscle and bone growth, cell reproduction, and cell regeneration in humans and other animals. [1] GH also plays a major role in increasing muscle mass and bone density, sugar and fat metabolism, regulating body fluids, and maintaining the health of all human tissues, including vital organs such as the heart and brain.
