GHRP-2, also known as Pralmorelin, is a growth hormone secretagogue that stimulates the release of growth hormone from the pituitary gland. It functions by binding to the growth hormone secretagogue receptor, enhancing the secretion of growth hormone in the body. Scientists initially studied GHRP-2 for its potential to promote growth and development in various physiological processes. Researchers are also looking at its effects on metabolic functions and tissue repair. Today, it is primarily studied for its effects on:

Growth stimulation
Metabolic function
Tissue repair
Appetite regulation
Cardiovascular health

Further investigations are examining its role in immune system modulation.
