CJC-1295 research guide for Kelekli. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Kelekli searching for CJC-1295, the first thing to know is that this compound is available only through an online research supply market. The practical advantage of this online-only market is that serious vendors are judged entirely by their analytical documentation, giving researchers better verification tools than any local market ever offers. Vendors worth sourcing from openly share batch-matched Certificates of Analysis showing HPLC purity data, mass spec identity confirmation, endotoxin levels, and residual solvent results — all for the exact batch you are purchasing. The sections below cover what Kelekli researchers need to know about purchasing, testing, and working with 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 Kelekli researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
How to Source CJC-1295 — Vendor Guide
Quality CJC-1295 sourcing begins with a simple filter: does this vendor share complete COA data without being asked? Vendors who do are demonstrating research-grade standards. When reviewing a CJC-1295 COA, verify: the batch number corresponds to your vial, HPLC purity is ≥98%, mass spec confirms the correct peptide, and endotoxin levels are below the threshold for research use. The combination of community reputation data and your own COA analysis is the most effective quality filter — community feedback surfaces systemic problems invisible in one transaction, and vice versa. The lyophilised (freeze-dried) form of CJC-1295 is always preferable to liquid pre-made solutions — lyophilised powder maintains stability for years when frozen, while liquid preparations lose activity within weeks.

CJC-1295 operates outside approved pharmaceutical regulation — researchers should understand that the risk characterisation for this compound is based on preclinical evidence rather than regulated clinical data. Storage requirements for CJC-1295: lyophilised powder at minus 20°C, reconstituted solution stored refrigerated at 2-8°C and consumed within 4 weeks; reconstitute only with bacteriostatic water. Endotoxin testing in the CJC-1295 COA is non-negotiable — gram-negative bacterial endotoxins can trigger severe inflammatory responses at minute levels, and no pricing advantage justifies skipping this verification. Researchers running multi-compound protocols with CJC-1295 should review the available literature for documented interactions before proceeding with any multi-compound protocol.
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.
