Overview

CJC-1295 (with DAC) is a synthetic peptide analogue of Growth Hormone-Releasing Hormone (GHRH), a 44-amino-acid hypothalamic peptide that stimulates pituitary somatotroph cells in vivo. The CJC-1295 sequence corresponds to GHRH(1-29) with substitutions to improve protease resistance, conjugated to a Drug Affinity Complex (DAC) moiety that covalently binds to serum albumin after reconstitution, prolonging circulating half-life in pharmacokinetic model studies. It is used in research settings to study the GHRH–GH axis signaling dynamics and receptor binding kinetics.

Key Facts

  • Analogue of GHRH(1-29) — the biologically active fragment of the 44-amino-acid hypothalamic hormone
  • DAC moiety enables covalent binding to serum albumin for extended half-life in PK studies
  • Amino acid substitutions at positions 2, 8, 15, and 27 increase resistance to dipeptidyl peptidase IV (DPP-IV)
  • Endogenous GHRH is secreted in pulsatile fashion from the arcuate nucleus of the hypothalamus
  • Lyophilized; reconstituted with bacteriostatic water for in vitro or animal model studies
  • Strictly for in vitro and animal model research — not for human or veterinary use
