GnRH is a hormone that is produced in the hypothalamus region of the brain. Once produced, GnRH moves through the bloodstream to the pituitary gland. There, it binds to certain receptors, which signals the pituitary gland to create two more hormones: LH and follicle-stimulating hormone (FSH).
Growth hormone (GH or HGH), 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.GH is a stress hormone that raises the concentration of glucose and free fatty acids. It also stimulates production of IGF-1.rowth 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.
