For anyone in Vigy searching for CJC-1295, the foundational reality is that this compound is distributed via specialist online vendors. This concentration of supply in online vendors is ultimately a quality advantage — top vendors distinguish themselves through rigorous testing in ways no local retailer can match. A legitimate CJC-1295 supplier's COA needs to show HPLC purity, mass spectrometry confirmation of molecular identity, bacterial endotoxin testing, and a residual solvents panel — all traceable to your specific batch. This guide takes Vigy researchers through that evaluation process and explains what quality documentation for CJC-1295 should look like.
Understanding CJC-1295 — Biology & Evidence
CJC-1295 with DAC (Drug Affinity Complex) is a GHRH analogue with an extended half-life achieved through DAC technology that enables covalent binding to albumin. This modification extends the half-life from minutes (for native GHRH) to approximately 6-8 days, creating a sustained elevation in basal GH levels rather than the pulsatile pattern produced by GHRP compounds. This pharmacokinetic distinction is significant for research design: CJC-1295 based on CJC-1295 with DAC produces a different GH secretion pattern than GHRP compounds, with different downstream effects on IGF-1 and protein synthesis. Researchers in Vigy comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Evaluate CJC-1295 Vendors
The first step for any Vigy researcher sourcing CJC-1295 is identifying 2-3 vendors with documented positive community reputations — search results alone are too heavily influenced by marketing spend. Mass spectrometry in the COA verifies that the main HPLC peak is actually CJC-1295 and not another compound with similar chromatographic behaviour — HPLC purity alone does not confirm what the compound actually is. Signs of a credible vendor beyond COA quality: documented vendor history spanning multiple years, responsive technical support who understand testing methodology, and cold chain packaging that protects product integrity. Bacteriostatic water is the correct reconstitution medium for CJC-1295 — it contains 0.9% benzyl alcohol that inhibits bacterial growth and extends reconstituted shelf life to 30 days refrigerated.

COA-verified · International tracking · Research grade
CJC-1295 is available for research use only and is not approved for human consumption by the FDA or comparable health authorities — all information here is provided for educational purposes. Temperature excursions — even short periods above −20°C — can cause partial degradation without detectable changes to appearance; always use only material shipped with appropriate cold protection. Endotoxin testing in the CJC-1295 COA is non-negotiable — gram-negative bacterial endotoxins can trigger severe inflammatory responses at minute levels, and no discount compensates for this missing data. Protocol documentation — documenting product details, dates, and administration precisely — is a sound practice for any CJC-1295 protocol that allows any unexpected observations to be properly contextualised.
Frequently Asked Questions
What purity is required for CJC-1295 research?
CJC-1295 should be ≥98% pure by HPLC. The larger molecular weight of CJC-1295 with DAC (approximately 3647 Da) makes mass spectrometry confirmation particularly important, as impurities may not be obvious on HPLC alone.
What is CJC-1295?
CJC-1295 is a synthetic GHRH (Growth Hormone Releasing Hormone) analogue. The version with DAC (Drug Affinity Complex) has an extended half-life of approximately 6-8 days due to albumin binding. Without DAC, CJC-1295 has a much shorter half-life similar to native GHRH. Both versions stimulate pulsatile GH release via the GHRH receptor.
What is the difference between CJC-1295 with DAC and without DAC?
CJC-1295 with DAC uses a lysine-maleimide conjugate to bind covalently to albumin in the bloodstream, extending half-life to ~6-8 days and creating sustained GH elevation. CJC-1295 without DAC (also called Mod GRF 1-29) has a half-life of ~30 minutes and produces acute GH pulses. They produce different GH secretion patterns and have different applications in research.
