Human Growth Hormone (HGH)

Growth hormone is a polypeptide hormone synthesised and secreted by the anterior pituitary gland which stimulates growth and cell reproduction in humans and other vertebrate animals.
Although height growth is the best known effect of GH, it serves many other metabolic functions as well. GH increases calcium retention, and strengthens and increases the mineralization of bone. It increases muscle mass. It induces protein synthesis and growth of many different organ systems of the body, resulting in a "positive nitrogen balance".
