Protirelin is a hormone made up of three building blocks that can help condition the skin in cosmetics. It is naturally found in humans and is produced by cells in the brain called neurons. When released into the bloodstream, it tells another gland called the anterior pituitary to release two other hormones - thyroid-stimulating hormone and prolactin. These hormones can help regulate the body's metabolism and milk production, respectively. Protirelin is also found in other parts of the body like the gut and pancreas, where it may have different functions. Medical professionals use synthetic versions of protirelin to test for thyroid disorders or a condition called acromegaly which causes abnormal growth due to too much growth hormone being produced by another gland called the pituitary.
