Human growth hormone (HGH) has been called a miracle anti-ageing drug -- it's widely used in alternative clinics for the elderly as a means of rejuvenation. Human growth hormone is an effective anti-ageing drug due to its ability to return an adult's hormone levels to those of their youth.

Human growth hormone (HGH) has been used by body builders for years to promote physical enhancement. When a person's pituitary glands release human growth hormone, it causes their liver to release IGF-1. IGF-1 is at its highest in childhood, and, as a person ages, the level of HGH their body.

HGH is a natural substance that is excreted by the pituitary glands in the human body. As a person ages, the level of HGH that their body produces, decreases. However, human growth hormone drugs work to raise a person's levels of HGH back to a youth-like level, therefore aiding in weight loss.
