Growth hormone
Growth hormone secretagogues or GH secretagogues (GHSs) are a class of drugs which act as secretagogues (i.e., induce the secretion) of growth hormone (GH). They include agonists of the ghrelin/growth hormone secretagogue receptor (GHSR), such as ghrelin (lenomorelin), pralmorelin (GHRP-2), GHRP-6, examorelin (hexarelin), ipamorelin, and ibutamoren (MK-677), and agonists of the growth hormone-releasing hormone receptor (GHRHR), such as growth hormone-releasing hormone (GHRH, somatorelin), CJC-1295, sermorelin, and tesamorelin.
