Unlike everyday supplements stocked in every health store, CJC-1295 is distributed via a specialist research supply market that Perre residents access almost entirely online. The benefit of this online-only market is that serious vendors differentiate entirely through their analytical documentation, giving researchers better verification tools than any local market ever offers. A properly operating CJC-1295 supplier's COA should include HPLC purity, mass spectrometry confirmation of molecular identity, bacterial endotoxin testing, and a residual solvents panel — all traceable to your specific batch. The sections below cover what Perre researchers need to know about purchasing, testing, and working with CJC-1295 for scientific research use.
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 Perre comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Source CJC-1295 — Vendor Guide
Quality CJC-1295 sourcing begins with a useful first test: does this vendor publish batch-specific COAs proactively? Those who make this data freely available are demonstrating research-grade standards. The HPLC analytical chromatogram is the most important document in the COA: it should show a large primary peak representing CJC-1295, with negligible secondary peaks representing impurities — purity should be 98% or higher. Signs of a credible vendor beyond COA quality: documented vendor history spanning multiple years, customer service that can discuss analytical methods, and temperature-appropriate packaging with desiccant. For Perre researchers making a first CJC-1295 purchase: verify the vendor against this framework, begin with a small order, and verify batch traceability on arrival before use.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not been through the clinical trial process required for pharmaceutical approval — its safety profile is based on preclinical research and limited human studies. Reconstitute CJC-1295 with bacteriostatic water at the concentration suited to your research design; a standard 5mg vial with 2mL bac water yields 2.5mg/mL — or 25mcg per insulin syringe unit. The primary quality-related safety risk in CJC-1295 research is endotoxin contamination from poor sourcing — a verified endotoxin panel in the batch COA is the direct mitigation for this hazard. Protocol documentation — keeping clear records of compound, timing, and method — is a research best practice for CJC-1295 that makes anomalous results interpretable.
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.
