CJC-1295 research guide for Sutton. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Sutton trying to locate CJC-1295, the first thing to know is that this compound is available only through an online research supply market. This matters because CJC-1295 quality varies dramatically across the market — from analytically confirmed high-purity product to material with significant impurity issues — and the vendor controls every quality variable. Vendors worth sourcing from make readily available batch-matched Certificates of Analysis containing HPLC purity analysis, mass spec identity confirmation, endotoxin levels, and residual solvent results — all for the specific lot you are purchasing. The sections below cover what Sutton researchers need to know about sourcing, verifying, and handling CJC-1295 for research purposes.
Understanding CJC-1295 — Biology & Evidence
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 Sutton researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
How to Source CJC-1295 — Vendor Guide
Before assessing any particular supplier, 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 verifying the correct molecular weight, endotoxin test results, and a residual solvent panel — all traceable to your batch. For Sutton researchers evaluating unfamiliar vendors: a test quantity before committing to research volumes before committing to research quantities is standard practice in the community. Price is an ineffective primary criterion for CJC-1295 quality — research-grade synthesis and testing has genuine production costs that cannot be cut without consequences, so the lowest-priced options almost always involve trade-offs.

All use of CJC-1295 in Sutton or anywhere must be research use only — this compound is not approved for therapeutic human application, and all handling should follow research laboratory protocols. Lyophilised CJC-1295 should be frozen at −20°C as soon as it arrives; repeated freeze-thaw cycles of reconstituted material should be avoided by aliquoting into single-use portions. The most significant preventable safety hazard in CJC-1295 research is bacterial endotoxin from low-quality material — a confirmed endotoxin test result in the lot-matched COA is the key safeguard. The research literature on CJC-1295 should be studied thoroughly before beginning any research — study methodologies, dosing, and endpoints vary significantly and results do not always generalise across models.
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.
