GHRP-2

GHRP-2 (pralmorelin) is a synthetic hexapeptide — a chain of six amino acids with the sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2. It has a molecular formula of C₄₅H₅₅N₉O₆, a molecular weight of 817.99 g/mol, and a CAS number of 158861-67-7. The peptide incorporates two unnatural D-amino acids and the non-standard residue D-2-naphthylalanine, giving it a structure distinct from naturally occurring peptides. GHRP-2 was developed in the early 1990s and is classified as a growth hormone secretagogue and ghrelin receptor agonist. It is supplied as a white to off-white lyophilized powder that dissolves readily in water. This product is for research purposes only.
