CJC-1295 research guide for Kord Kūy. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Kord Kūy trying to locate CJC-1295, the first thing to know is that this compound is distributed via specialist online vendors. What this means for Kord Kūy researchers is that physical proximity is irrelevant compared to your ability to assess COA data — and those verification methods are accessible to anyone. The key verification criteria for CJC-1295 are HPLC purity ≥98%, molecular identity verified through mass spectrometry, and a bacterial endotoxin panel — all documented in a lot-traced Certificate of Analysis. What follows is a vendor evaluation and quality guide built specifically around CJC-1295, covering everything a Kord Kūy researcher needs to evaluate quality systematically.
Understanding CJC-1295 — Biology & Evidence
CJC-1295 with DAC (Drug Affinity Complex) is a GHRH analogue with an extended half-life achieved through DAC technology that enables covalent binding to albumin. This modification extends the half-life from minutes (for native GHRH) to approximately 6-8 days, creating a sustained elevation in basal GH levels rather than the pulsatile pattern produced by GHRP compounds. This pharmacokinetic distinction is significant for research design: CJC-1295 based on CJC-1295 with DAC produces a different GH secretion pattern than GHRP compounds, with different downstream effects on IGF-1 and protein synthesis. Researchers in Kord Kūy comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
CJC-1295 Purchasing Guide
Vetting CJC-1295 vendors requires starting from the COA: request the batch-specific certificate before placing an order, not after. When reviewing a CJC-1295 COA, verify: the batch number traces to your order, HPLC purity is ≥98%, mass spec identifies the correct molecular weight, and endotoxin levels are below the threshold for research use. Warning signs in CJC-1295 vendor evaluation: prices significantly below market average, unclear production details, no community presence, and COAs that do not include endotoxin results. The dry lyophilised powder of CJC-1295 is much more stable than liquid pre-made solutions — lyophilised powder stays viable for years at −20°C, while liquid preparations break down rapidly even under refrigeration.

COA-verified · International tracking · Research grade
CJC-1295 is available for research use only and is not approved for human therapeutic use by the FDA or comparable health authorities — all information here is provided for educational purposes. Storage requirements for CJC-1295: lyophilised powder at minus 20°C, reconstituted solution stored refrigerated at 2-8°C and finished within 30 days of reconstitution; reconstitute only with bacteriostatic water. Bacterial endotoxin contamination is the greatest safety hazard unique to this class of compound — verify endotoxin testing is documented in your batch COA before any injectable research application. Protocol documentation — keeping clear records of compound, timing, and method — is a sound practice for any CJC-1295 protocol that ensures unusual findings can be explained.
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.
