For anyone in Agres looking to source CJC-1295, the key fact to understand is that this compound is distributed via specialist online vendors. This matters because CJC-1295 quality varies dramatically across the market — from verified research-grade material to mislabeled or underdosed compounds — and the vendor controls every quality variable. Vendors worth sourcing from proactively publish batch-matched Certificates of Analysis showing HPLC purity data, mass spec identity confirmation, endotoxin levels, and residual solvent results — all for the specific lot you are purchasing. The sections below cover what Agres researchers need to know about purchasing, testing, and working with CJC-1295 for research purposes.
The Science Behind CJC-1295
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 Agres comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Source CJC-1295 — Vendor Guide
Before looking at individual vendors, build a clear picture of what a proper COA looks like — so you can tell whether a COA is complete and credible. A COA for CJC-1295 should include: HPLC purity percentage with the actual chromatogram data, mass spectrometry data verifying the correct molecular weight, endotoxin test results, and a residual solvent panel — all specific to the lot you receive. Signs of a credible vendor beyond COA quality: established track record of at least two years, customer service that can discuss analytical methods, 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 prevents microbial contamination and extends reconstituted shelf life to 30 days refrigerated.

As a research compound, CJC-1295 has not undergone the clinical trial process required for pharmaceutical approval — its safety profile is characterised by preclinical data and limited human studies. Reconstitute CJC-1295 with bacteriostatic water at a concentration matched to your dosing requirements; a standard 5mg reconstituted in 2mL produces 2.5mg/mL — or 25mcg per insulin syringe unit. Quality CJC-1295 sourcing is not separable from research safety — bacterial endotoxin contamination, incorrect identity, and breakdown products are all safety issues that verified-quality sourcing directly prevents. PubMed and bioRxiv represent the most comprehensive research databases for CJC-1295 research; favour indexed journal publications over preprints over unreviewed preprints or forum reports.
Frequently Asked Questions
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.
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.
