Human Growth Hormone (hGH) – History, Side-Effects, Use in Baseball

Human growth hormone (hGH) is a polypeptide hormone synthesized and secreted by the anterior pituitary gland which stimulates growth and cell reproduction in humans and other vertebrate animals. In the liver, hGH converts to insulin-like growth factor-1 promoting growth. Secretion levels are highest during puberty and decrease during adulthood and are directly related to aging.
