Somatropin (Human Growth Hormone): Production & Function

Somatropin, also known as Human Growth Hormone (HGH) or even sometimes just Growth Hormone (GH) is a hormone created in the pituitary gland dealing with growth. Before somatropin can be created, Human Growth Hormone Releasing Hormone (HGHRH) and Somatostatin (SST) are released by the Hypothalamus. Many factors can influence HGH release, of which the main…
