Human growth hormone or HGH . Synthetic form can be safe and useful as a treatment for some medical conditions. However, it is not intend to be use as ananti-aging medication. No evidence exists that shows HGH works against the effects of aging. In fact, taking HGH may be dangerous for some people.
What is human growth hormone?
Growth hormone (GH), is a small protein that is produce by the pituitary gland and secret into the bloodstream. GH production is control by a complex set of hormones produce in the hypothalamus, of the brain and in the intestinal tract and pancreas.
The pituitary puts out GH in bursts; levels rise following exercise, trauma, and sleep. Under normal conditions, more GH is produce at night than during the day. This physiology is complex, but at a minimum, it tells us that sporadic blood tests to measure GH levels are meaningless since high and low levels alternate, throughout the day. But scientists who carefully measure overall GH production report that it rises during childhood, peaks during puberty, and declines from middle age onward.
GH acts on many tissues throughout the body.
In children and adolescents, it stimulates the growth of bone and cartilage. In people of all ages, GH boosts protein production, promotes the utilization of fat, interferes with the action of insulin, and raises blood sugar levels. GH also raises levels of insulin-like growth factor-1 (IGF-1).
