Human growth hormone, also known as somatotropin, is a protein that is composed of 191 amino acids. It is released by the anterior of the pituitary gland. From birth until the end of the growth and development stage of life HGH is responsible for the rapid growth of bone, muscle, organs, etc. However, once the growth and development stage is completed, usually during the mid twenties, the release of growth hormone begins its slow decline and continues to decline as age progresses.
In the past it was believed by physicians in modern mainstream medicine that growth hormone was only important during the time of growth and development. Unfortunately, in 2022 some physicians still believe this to be the case, even though scientific evidence showing the many benefits of restoring the HGH of aging adults to a more youthful and healthy level continues to pile up.
When growth hormone is released by the pituitary gland it remains in the bloodstream for only a couple of minutes. It is quickly taken into the liver and is converted into growth factors, the main one being insulin-like growth factor - 1 (IGF-1). Growth factors are the messengers that go to each cell and prompts the new cell growth that replaces the old, damaged cells with new healthy cells. This is how the body heals and rejuvenates itself.
As age progresses and the natural release of growth hormone continues to decline the less growth factors we will have to prompt the new cell growth that rebuilds the body cell by cell. This is one of the main reasons why the skin becomes wrinkled, we don't have the energy and stamina we once had, our organs don't work as well, etc., because our cells are no longer being quickly renewed like they were when we were younger.
I have written many articles about growth hormone over the past 23 years. For more specific information, including the side effects of decreasing growth hormone please see these articles:
