Growth hormone (hgh powder or hgh191aa powder ), also known as somatotropin or somatropin, is a peptide hormone that stimulates growth, cell reproduction and regeneration in humans and other animals. It is a type of mitogen which is specific only to certain kinds of cells. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland.hgh is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1.
HGH is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor. In recent years in the United States, some doctors have started to prescribe growth hormone in GH-deficient older patients (but not on healthy people) to increase vitality. While legal, the efficacy and safety of this use for hgh191aa has not been tested in a clinical trial. At this time, hgh191aa is still considered a very complex hormone, and many of its functions are still unknown
