CJC-1295 isn't stocked on pharmacy shelves in Siwei or virtually any local market — it's a research compound available through a dedicated online market. This online-only market structure is a genuine benefit for researchers — top vendors differentiate through analytical documentation in ways no local retailer can match. A credible CJC-1295 supplier's COA should include HPLC purity, mass spectrometry confirmation of molecular identity, bacterial endotoxin testing, and a residual solvents panel — all batch-matched to your order. This guide gives Siwei researchers the practical tools to evaluate CJC-1295 vendors systematically and source high-purity CJC-1295 with confidence.
CJC-1295: What the Research Shows
CJC-1295 belongs to the growth hormone secretagogue (GHS) class, compounds that stimulate pulsatile growth hormone release by acting on the ghrelin receptor (GHSR-1a) or growth hormone releasing hormone (GHRH) receptor. Ipamorelin, GHRP-2, GHRP-6, and Hexarelin all work primarily through GHSR-1a agonism, producing GH pulses with varying specificity profiles. CJC-1295 and Sermorelin work through the GHRH receptor, mimicking the natural hypothalamic signal for GH release. The downstream effect in both cases is increased pulsatile GH secretion and subsequent IGF-1 production in the liver. For researchers in Siwei studying the GH-IGF-1 axis, this mechanistic clarity makes the GHS class a productive experimental tool.
Where to Buy CJC-1295 — A Researcher's Guide
Quality CJC-1295 sourcing begins with a straightforward question: does this vendor make batch-matched COAs available before purchase? Suppliers that publish proactively are signalling genuine quality commitment. The HPLC analytical chromatogram is the most important document in the COA: it should show a clear dominant peak representing CJC-1295, with minimal secondary peaks representing impurities — purity should be stated as ≥98%. For Siwei researchers evaluating unfamiliar vendors: a small initial order to verify quality before scaling up your order is the accepted approach among experienced researchers. Store lyophilised CJC-1295 at minus 20 degrees Celsius until ready to use; reconstitute only the amount needed for the near-term protocol and keep the remainder frozen.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not undergone the clinical trial process required for pharmaceutical approval — its safety profile is defined by animal study data and restricted human research data. 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. Bacterial endotoxin contamination is the greatest safety hazard associated with research-grade peptides — verify endotoxin testing is present in the lot-matched certificate before any injectable research application. PubMed and related preprint servers provide the most complete literature coverage for CJC-1295 research; prioritise peer-reviewed studies with characterised source material 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 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 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.
