For anyone in Rax searching for CJC-1295, the foundational reality is that this compound is distributed via specialist online vendors. This online-only market structure is actually an advantage for quality — top vendors compete on lab-verified purity in ways brick-and-mortar outlets simply cannot. What genuinely separates top CJC-1295 vendors is full COA coverage: HPLC for purity, mass spec for identity and weight verification, and endotoxin testing for safety screening. This guide gives Rax researchers the methodology to verify sourcing options methodically and source verified-quality CJC-1295 with confidence.
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 Rax researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
CJC-1295 Purchasing Guide
Quality CJC-1295 sourcing begins with a useful first test: does this vendor share complete COA data without being asked? Suppliers that publish proactively are operating transparently. Mass spectrometry in the COA establishes that the main HPLC peak is actually CJC-1295 and not another compound with similar chromatographic behaviour — HPLC purity alone cannot verify molecular identity. For Rax researchers evaluating new suppliers: a small initial order to verify quality before committing to research quantities is standard practice in the community. The lyophilised (freeze-dried) form of CJC-1295 is far superior to liquid pre-made solutions — lyophilised powder stays viable for years at −20°C, while liquid preparations lose activity within weeks.

COA-verified · International tracking · Research grade
All use of CJC-1295 in Rax or anywhere must be research use only — this compound is not approved for human therapeutic use, and all handling should adhere to research compound handling standards. Storage requirements for CJC-1295: lyophilised powder at −20°C, reconstituted solution kept at 2-8°C refrigerated and used within 30 days; reconstitute only with sterile bacteriostatic water. Verify the endotoxin level in your CJC-1295 batch COA before use in any in-vivo protocol — look for results expressed as EU/mg or EU/mL and compare against acceptable research limits for your application. Researchers running multi-compound protocols with CJC-1295 should examine published studies for potential interaction data before beginning combination research.
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.
