Examorelin

Examorelin (INN) (developmental code names EP-23905, MF-6003), also known as hexarelin, is a potent, synthetic, peptidic, orally-active, centrally-penetrant, and highly selective agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and a growth hormone secretagogue which was developed by Mediolanum Farmaceutici. It is a hexapeptide with the amino acid sequence His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 which was derived from GHRP-6 (which, in turn, is an analogue of ghrelin).
