Growth Hormone (GH) is the master hormone, because it is released by the master gland--the anterior pituitary gland. While GH is not necessary or critical to one's survival, it seems to play an important evolutionary role in human development. During puberty, GH levels dictate a person's height and bone size. After puberty, GH continues to regulate the body's metabolism.
