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. These GH-releasing peptides have no sequence similarity to ghrelin, but mimic ghrelin by acting as agonists at the ghrelin receptor. Examorelin substantially and dose-dependently increases plasma levels of growth hormone (GH) in animals and humans. In addition, similarly to pralmorelin (GHRP-2) and GHRP-6, it slightly and dose-dependently stimulates the release of prolactin, adrenocorticotropic hormone (ACTH), and cortisol in humans. There are conflicting reports on the ability of examorelin to elevate insulin-like growth factor 1 ( ...
