Examorelin or also known as hexarelin is a synthetic, six-amino0acid compound, potent peptide and highly selective agonist of growth hormone secretagogue receptor and a growth hormone (GH) secretagogue. It stimulates the release GH both in vitro and in vivo. When compared with ghrelin, hexarelin is chemically more stable and functionally more potent. Therefore, it may be a promising therapeutic agent for some cardiovascular conditions. Studies showed that intravenous administration of these peptides online produces a substantial and dose-dependent increase in growth hormone plasma concentrations. Other studies show that the effects of hexarelin on GH release in adults has been for 15 days.
