HGH (Human Growth Hormone) is the primary naturally occurring hormone in the family of endocrine hormones. Estrogen, Progesterone, Testosterone, melatonin and DHEA are other key hormones, and all have an important function in our daily lives.

What all of these hormones have in common is that they all decline with age. Some physicians offer replacement of these hormones to deter the signs of aging, which has become a highly controversial topic in the health, and wellness community.

HGH, also known as Somatotropin and somatotropic hormone (STH), is the most abundant endocrine hormone secreted by the pituitary gland. HGH stimulates growth of body tissues, especially skeletal and muscular tissues.
