GHRP-2

CAS 158861-67-7

A synthetic hexapeptide (D-Ala-D-beta-Nal-Ala-Trp-D-Phe-Lys-NH2, CAS 158861-67-7), also known as pralmorelin (KP-102). Agonizes the ghrelin/GHS-R1a receptor to drive pulsatile GH release with ancillary appetite-stimulating activity. Approved in Japan as a single-dose diagnostic reagent (GHRP Kaken) for confirming adult growth hormone deficiency; not approved in the US or EU as a therapy or diagnostic. Commonly co-administered with a GHRH analog (sermorelin, CJC-1295) in research protocols.
