Growth hormone is a protein-based peptide which stimulates growth, cell reproduction, and regeneration in humans and animals.. Growth hormone injections are used to treat children’s growth disorders/growth hormone deficiencies because their pituitary glands cannot produce the proper amount of growth hormones resulting in a short stature..
