Description
Product overview
CJC-1295 (No DAC) — also known as Modified GRF(1–29) or Mod GRF(1–29) — is a synthetic, tetrasubstituted analogue of growth hormone–releasing hormone (GHRH). Unlike the DAC version, CJC-1295 No DAC lacks the Drug Affinity Complex that extends half-life in vivo, making it well-suited for in-vitro studies of GHRH receptor (GHRHR) signalling where a defined, short-duration stimulus is required. Avanti Peptides supplies it as a lyophilised solid for stable, consistent research use.
Key features
- GHRH analogue (non-DAC) — ideal for in-vitro GHRHR signalling and GH-axis biology studies
- Tetrasubstituted Mod GRF(1–29) — enhanced protease resistance versus native GHRH(1–29)
- Lyophilised solid — stable, easy to store, and straightforward to reconstitute
- Unit size: 5 mg per vial
- Every batch released only after stringent identity, purity, and appearance QC
- Certificate of Analysis (CoA) and batch documentation available on request

Reconstitution & storage
- Before reconstitution: Store lyophilised vials at 2–8 °C, protected from light and moisture.
- Equilibrate: Allow vial and diluent to reach room temperature before opening.
- Reconstitute: Add Bacteriostatic Water (10 ml recommended). Swirl gently — do not vortex.
- After reconstitution: Store at 2–8 °C. Prepare aliquots to minimise freeze–thaw cycles.
- Compatibility: Use only within protocols that comply with your institution’s SOPs and local regulations.

About CJC-1295 (No DAC) in research
Researchers use CJC-1295 (No DAC) to investigate GHRH receptor activation, downstream GH-axis signalling cascades, and the effect of GHRH analogues on pituitary cell models in vitro. Its tetrasubstituted sequence confers greater stability than native GHRH(1–29) while the absence of a DAC moiety allows study of short-duration receptor stimulation kinetics.
Synthesis & quality assurance
Avanti Peptides manufactures CJC-1295 (No DAC) via controlled, validated solid-phase peptide synthesis (SPPS) to deliver high purity and lot-to-lot consistency. Each batch undergoes identity verification, HPLC purity analysis (≥99%), and appearance inspection before release. Certificate of Analysis (CoA) documentation is available upon request.
