Human Growth Hormone (rHGH, HGH, or GH), as the name suggests is a hormone that is responsible for the growth of the body through cell reproduction and regeneration.Also called somatropin, it is produced in the somatotropic cells in the pituitary gland.GH is primarily responsible for the proper growth of our bones, muscles and other tissues among children. Deficiency of this hormone would result in stunted growth of the human body.
Prolactin and growth hormone act upon certain body tissues; they do not affect specific organs. Prolactin travels to the breast tissue glands of nursing mothers, causing milk production. Growth hormone stimulates protein synthesis and cell division in cartilage and bone tissue. Gigantism results when excessive amounts of growth hormone are produced during childhood.
