Description
CJC-1295 (No DAC) | GHRH Analogue, Research Grade
CJC-1295 without Drug Affinity Complex (No DAC) is a 30-amino acid synthetic analogue of growth hormone-releasing hormone (GHRH). Unlike the DAC version, it preserves the natural pulsatile pattern of GH release, making it widely used in GH axis research.
Mechanism of Action
- GHRH receptor agonism, binds and activates the GHRH receptor on somatotroph cells of the anterior pituitary
- Pulsatile GH release, stimulates GH secretion while maintaining physiological pulse architecture
- IGF-1 elevation, downstream increase in hepatic IGF-1 production studied in deficiency models
Research Areas
CJC-1295 (No DAC) is studied in GH deficiency, body composition, metabolic syndrome, and aging research. It is frequently investigated alongside GHRPs (Ipamorelin, GHRP-6) for synergistic GH pulse amplification.
Independent Lab Verification
Rainbow Peptide works with independent, accredited third-party laboratories, including Vanguard Laboratory (ISO 17025:2017-accredited, A2LA Certificate #6377.01.01), to verify compound identity and purity. A Certificate of Analysis is included with every order.
For Research Use Only. Rainbow Peptide supplies CJC-1295 exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.






Dr. P. Larsen –
CJC-1295 without DAC is a standard in our GH secretagogue research panel. Rainbow Peptide’s lot had 98.8% purity confirmed by reverse-phase HPLC. In vitro GH release assay showed response consistent with published benchmarks. High-quality supplier.
B. Ashworth –
Reordering CJC-1295 for the third time. Our longitudinal GH axis study requires identical batches, and the consistency here has been excellent. COA matched our in-house testing. Dissolved cleanly in sterile water.
F. Nguyen –
CJC-1295 arrived quickly and in good condition. Purity verified at 98.3%. The peptide performed as expected in our receptor binding assay. COA included molecular weight confirmation. Will reorder for upcoming study.
