Growth hormone (GH) is a single peptide chain protein hormone secreted by eosinophils in the anterior pituitary gland. It is a growth regulator with a wide range of physiological functions. It can affect almost all tissue types and cells. It is mainly used for children with growth disorders and dwarfism and short stature caused by insufficient secretion of endogenous pituitary growth hormone. In addition, it can also be used to treat burns, fractures, trauma, hemorrhagic ulcers, tissue necrosis, muscular dystrophy, osteoporosis and other diseases.
