For anyone in Grawn looking to source CJC-1295, the foundational reality is that this compound is available only through an online research supply market. What this means for Grawn researchers is that geography is secondary to your ability to verify analytical documentation — and those verification methods are within reach of all serious researchers. 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 corresponding to the vial you receive. The sections below cover what Grawn researchers need to know about purchasing, testing, and working with CJC-1295 for scientific research use.
How CJC-1295 Works — Mechanisms & Research
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 Grawn researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
CJC-1295 Purchasing Guide
Before evaluating any specific vendor, establish a quality benchmark — so you can tell whether a COA is complete and credible. Mass spectrometry in the COA verifies that the main HPLC peak is actually CJC-1295 and not a different peptide of similar polarity — HPLC purity alone does not confirm what the compound actually is. Community reputation in research forums is a complementary signal to COA verification — vendors with multi-year positive track records have built their reputation on real product performance. Price is an unreliable primary filter for CJC-1295 quality — research-grade synthesis and testing has genuine production costs that cannot be cut without consequences, so unusually low prices consistently indicate quality reductions.

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 characterised by preclinical data and restricted human research data. Storage requirements for CJC-1295: lyophilised powder at minus 20°C, reconstituted solution refrigerated at 2-8°C and finished within 30 days of reconstitution; reconstitute only with bacteriostatic water. Endotoxin testing in the CJC-1295 COA is not optional — gram-negative bacterial endotoxins can trigger serious inflammatory reactions at trace quantities, and no pricing advantage justifies skipping this verification. Protocol documentation — keeping clear records of compound, timing, and method — is a sound practice for any CJC-1295 protocol that allows any unexpected observations to be properly contextualised.
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.
