CJC-1295 research guide for Chunian. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Chunian looking to source CJC-1295, the key fact to understand is that this compound is available only through an online research supply market. What this means for Chunian researchers is that your location matters far less than your ability to verify analytical documentation — and those evaluation tools are accessible to anyone. A credible 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. What follows is a vendor evaluation and quality guide built specifically around CJC-1295, covering everything a Chunian researcher needs to source confidently.
CJC-1295 Mechanisms Explained
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 Chunian comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Source CJC-1295 — Vendor Guide
Assessing CJC-1295 vendors begins with the COA: locate the batch-specific certificate before placing an order, not after. The HPLC analytical chromatogram is the most important document in the COA: it should show a clear dominant peak representing CJC-1295, with negligible secondary peaks representing impurities — purity should be at or above 98%. For Chunian researchers evaluating vendors with limited track records: a modest first purchase to test the product before committing to research quantities is what experienced peptide researchers consistently do. Keep lyophilised CJC-1295 at minus 20 degrees Celsius until ready to use; reconstitute only the quantity required for your immediate research and store the rest at −20°C.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not completed the clinical trial process required for pharmaceutical approval — its safety profile is defined by animal study data and small-scale human observations. Storage requirements for CJC-1295: lyophilised powder at freezer temperature, reconstituted solution refrigerated at 2-8°C and consumed within 4 weeks; reconstitute only with sterile bacteriostatic water. Endotoxin testing in the CJC-1295 COA is non-negotiable — gram-negative bacterial endotoxins can trigger severe inflammatory responses at very low concentrations, and no pricing advantage justifies skipping this verification. Protocol documentation — documenting product details, dates, and administration precisely — is a fundamental research principle that makes anomalous results interpretable.
Frequently Asked Questions
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.
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.
