CJC-1295 research guide for Reftele. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
CJC-1295 isn't found on pharmacy shelves in Reftele or virtually any local market — it's a research-grade peptide available through a dedicated online market. The practical advantage of this online-only market is that serious vendors are judged entirely by their analytical documentation, giving researchers more rigorous quality data than local retail ever could. The key verification criteria for CJC-1295 are HPLC purity ≥98%, molecular identity established via mass spectrometry, and a bacterial endotoxin panel — all documented in a batch-specific Certificate of Analysis. The sections below cover what Reftele researchers need to know about finding, evaluating, and storing CJC-1295 for research purposes.
The Science Behind CJC-1295
The selectivity profile of different GHS compounds is a critical research consideration. GHRP-6 and GHRP-2 produce GH release alongside cortisol and prolactin elevation — a confounding factor in research designs where these hormones are outcome variables. Ipamorelin was specifically developed for greater GH-release selectivity with minimal cortisol and prolactin elevation, making it more suitable for research designs where GH-specific effects need to be isolated. Hexarelin has the strongest GH-releasing potency in the GHRP class but also the most significant cortisol and prolactin effects. For Reftele researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
Sourcing Research-Grade CJC-1295
Before looking at individual vendors, build a clear picture of what a proper COA looks like — so you can identify whether a supplier meets the standard. A COA for CJC-1295 should include: HPLC purity percentage with the underlying chromatogram, mass spectrometry data confirming the correct molecular weight, endotoxin test results, and a residual solvent panel — all traceable to your batch. Strong quality indicators beyond COA quality: multi-year operating history, customer service that can discuss analytical methods, and temperature-appropriate packaging with desiccant. Bacteriostatic water is the correct reconstitution medium for CJC-1295 — it contains 0.9% benzyl alcohol that suppresses bacterial proliferation and extends reconstituted shelf life to 30 days refrigerated.

CJC-1295 is supplied strictly for research applications and is not approved for human use by the FDA or equivalent regulatory bodies — all information here is for educational purposes only. Storage requirements for CJC-1295: lyophilised powder at freezer temperature, reconstituted solution stored refrigerated at 2-8°C and used within 30 days; reconstitute only with bac water. Quality CJC-1295 sourcing directly determines safety outcomes — bacterial endotoxin contamination, mislabeling, and degradation products are all safety issues that rigorous vendor evaluation eliminates. PubMed are the primary literature resources for CJC-1295 research; focus on peer-reviewed publications with documented compound quality over conference abstracts or single case observations.
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.
