CJC-1295 without DAC is a 29-residue synthetic C-terminally amidated polypeptide corresponding to the 1-29 fragment of human growth hormone-releasing hormone. It carries four substitutions relative to the native fragment: D-alanine at position 2, glutamine at position 8, alanine at position 15 and leucine at position 27. The leucine substitution at position 27 removes the methionine residue of the native sequence, so the molecule contains no sulfur.

The molecular target is the growth hormone-releasing hormone receptor (GHRHR), a class B secretin- family G-protein-coupled receptor. Occupancy is quantified in recombinant GHRHR-expressing cell lines by competition displacement of a labelled reference ligand, yielding Ki and IC50 values. Functional coupling is recorded in the same transfected systems as cAMP accumulation. Reported values are properties of the specific construct, cell line, buffer and detection chemistry used and are not transferable between assay formats.
