CJC-1295 research guide for Stettlen. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Stettlen looking to source CJC-1295, the foundational reality is that this compound is available only through an online research supply market. This online-only market structure is actually an advantage for quality — top vendors distinguish themselves through rigorous testing in ways brick-and-mortar outlets simply cannot. What consistently distinguishes top CJC-1295 vendors is full COA coverage: HPLC for purity, mass spec for peptide identity confirmation, and endotoxin testing for safety screening. This guide guides Stettlen researchers through that evaluation process and explains the signals that distinguish quality CJC-1295 suppliers.
What Studies Say About 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 Stettlen researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
How to Evaluate CJC-1295 Vendors
Vetting CJC-1295 vendors requires starting from the COA: locate the batch-specific certificate before purchasing, not after. When reviewing a CJC-1295 COA, verify: the batch number traces to your order, HPLC purity is ≥98%, mass spec establishes identity, and endotoxin levels are at acceptable levels for the intended application. Community reputation in research forums is a valuable complement to COA verification — vendors with multi-year positive track records have built their reputation on real product performance. The dry lyophilised powder of CJC-1295 is always preferable to liquid pre-made solutions — lyophilised powder maintains stability for years when frozen, while liquid preparations break down rapidly even under refrigeration.

COA-verified · International tracking · Research grade
All use of CJC-1295 in Stettlen or anywhere constitutes research use — this compound is not approved for clinical human use, and all handling should comply with standard research safety practices. Reconstitute CJC-1295 with bacteriostatic water at a concentration matched to your dosing requirements; a standard 5mg reconstituted in 2mL produces 2.5mg/mL — providing 25mcg per unit measured on a 100-unit syringe. Verify the endotoxin level in your CJC-1295 batch COA before use in any in-vivo protocol — look for results stated as EU/mg and compare against acceptable research limits for your application. Protocol documentation — keeping clear records of compound, timing, and method — is a fundamental research principle that makes anomalous results interpretable.
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 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.
