Pairs two structurally distinct synthetic peptides. CJC-1295 (No DAC) / Modified GRF 1-29 is a 29-residue, C-terminally amidated analog corresponding to residues 1-29 of a 44-residue hypothalamic peptide, carrying four substitutions relative to the parent sequence (a D-alanine at position 2 plus changes at positions 8, 15, and 27) that confer resistance to enzymatic cleavage; its structural partner is a class B GPCR, characterized by cryo-EM. Hexarelin is a synthetic hexapeptide (His-D-2-MeTrp-Ala-Trp-D-Phe-Lys-NH2) whose structural partner is a class A GPCR; photoaffinity cross-linking has additionally identified the scavenger receptor CD36 as a binding partner in cardiac-membrane preparations. The two components are structurally unrelated and engage different binding partners; no single molecular target applies to the blend.
