Human growth hormone is a protein made of amino acids that are produced in the pituitary gland that is responsible for growth in children and adolescents. This hormone increases the height and muscle mass of children along with stimulating growth of all the organs except the brain. It also helps the immune system and works with the liver and pancreas with regulation of glucose and other maintenance of these organs.

There are certain conditions where people will not produce proper levels of HGH in the body, usually children. The term used for this is Human Growth Hormone Deficiency. This can happen from a damaged pituitary, brain tumor or congenital defects. Other conditions that can cause the need for HGH are Turner's Syndrome, chronic renal insufficiency, Intrauterine growth retardation, Prader-Willi syndrome and height deficiency at of after puberty. Adults can also experience conditions where HGH is not produced due to brain or pituitary damage or disorders. HGH is important in maintaining a healthy body with all aged people and when HGH is insufficient in adults this is called AGHD or adult growth hormone deficiency.

Injectable HGH is a manufactured HGH that has the same amino acids as what the pituitary gland produces. It is identical to real HGH chemically, physically and biologically and is only given with a prescription. The prescription is only FDA approved for children who have a hormone deficiency.

Many people are choosing to used this hormone for its anti-aging benefits. This use is not FDA approved but HGH is not illegal. As people age their HGH levels become lower. HGH can help slow the process of aging giving people improved memory, more energy, enhanced sex drive, weight loss and more muscle mass and many other positive benefits.

Injectable HGH is administered in the stomach or arms usually with some positive effects felt the next day but injections must continue for full benefits with results seen in less than six months. This form of HGH is much more effective than HGH supplements but must be taken under medical supervision.

When high doses of injectable HGH are given the side effects are more prevalent. Side effects can include arthritis, edema and carpal tunnel syndrome. Also people who eat diets that have high sugar and starch content and do not exercise regularly can experience high blood sugar and insulin levels.

In conclusion injectable HGH is the most effective form HGH but it also can be quite costly compared to supplements. Injections must be prescribed and people should be under close medical supervision when taking this product.
