Found in both pediatric and adult patients, growth hormone deficiency (GHD) is a condition in which a person's body does not produce the amount of growth hormone necessary for normal bone and muscle growth.

Human growth hormone has been used by body builders for years to promote physical enhancement. Human growth hormone raises your energy level and metabolism, causing you to both feel more active and burn fat.

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.
