Research brief
CJC-1295 — Canada Research Brief
Mechanism
CJC-1295 was developed by ConjuChem as a long-acting GHRH analogue. The backbone is the native GHRH (1-29) sequence with four substitutions (D-Ala²-Gln⁸-Ala¹⁵-Leu²⁷) that improve enzymatic stability. The DAC variant adds a maleimidopropionyl-lysine linker that forms a covalent bond with free cysteine residues on albumin shortly after injection — turning the peptide into an albumin-conjugated prodrug with a half-life of 6–8 days.
Mechanistically, CJC-1295 binds the GHRH receptor on pituitary somatotrophs and drives growth hormone secretion in pulses consistent with physiological GH rhythm. The DAC variant produces a sustained elevation in IGF-1 (the liver-derived output of the GH axis) while preserving physiological feedback via somatostatin — a distinction from exogenous recombinant GH.
Stacking with ipamorelin
The CJC-1295 + ipamorelin combination is the canonical GH-secretagogue research pair. GHRH analogues and ghrelin agonists act on different pituitary receptors, so their GH pulses add rather than compete. In rodent and early human studies the combination produced larger GH peaks than either compound alone at equivalent doses.
Storage
Store lyophilised CJC-1295 at −20°C protected from light. Reconstituted peptide is stable refrigerated at 2–8°C for 2–4 weeks. Avoid repeated freeze-thaw cycles.
Frequently asked questions
What is CJC-1295?
CJC-1295 is a synthetic 29-residue GHRH analogue built on the GRF(1-29) backbone with four substitutions plus a DAC linker. The standard "CJC-1295 with DAC" variant attaches a non-residue maleimidopropionyl lysine linker that binds covalently to plasma albumin via its free cysteine, extending the half-life to roughly 6–8 days. The "no-DAC" variant is equivalent to Modified GRF (1-29) and has a much shorter half-life.
What is the difference between CJC-1295 with DAC and without DAC?
CJC-1295 DAC carries an albumin-binding linker (Drug Affinity Complex) that extends its plasma half-life to 6–8 days and produces sustained growth hormone elevation. CJC-1295 no-DAC, functionally the same as Modified GRF (1-29), has a half-life of roughly 30 minutes and produces a pulsatile GH release pattern instead.
Why is CJC-1295 often stacked with ipamorelin?
GHRH analogues like CJC-1295 drive GH release from the pituitary via one receptor, while ghrelin receptor agonists like ipamorelin drive release via a different receptor. Used together, they produce a synergistic GH pulse larger than either alone. This is the scientific rationale behind the CJC-1295 + ipamorelin research combination. Neither compound is approved for human use.
What is CJC-1295's molecular weight?
CJC-1295 with DAC has a molecular weight of approximately 3,367.88 g/mol, a molecular formula of C152H252N44O42, and CAS number 863288-34-0.
