CJC-1295 research guide for Haksever. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Haksever searching for CJC-1295, the first thing to know is that this compound is distributed via specialist online vendors. The benefit of this online-only market is that serious vendors compete aggressively on their analytical documentation, giving researchers better verification tools than local retail ever could. The core quality markers for CJC-1295 are HPLC purity ≥98%, molecular identity confirmed by mass spectrometry, and a bacterial endotoxin panel — all documented in a batch-matched Certificate of Analysis. This guide takes Haksever researchers through that evaluation process and explains what quality documentation for CJC-1295 should look like.
CJC-1295: What the Research Shows
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 Haksever comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
Sourcing Research-Grade CJC-1295
The most consistent path to quality CJC-1295 is engaging research communities before vendor sites — peptide forums maintain informal vendor reputation databases that are more accurate than commercial vendor claims. A COA for CJC-1295 should include: HPLC purity percentage with the underlying chromatogram, mass spectrometry data establishing the correct molecular weight, endotoxin test results, and a residual solvent panel — all traceable to your batch. For Haksever researchers evaluating new suppliers: a modest first purchase to test the product before placing larger orders is what experienced peptide researchers consistently do. The lyophilised (freeze-dried) form of CJC-1295 is much more stable than liquid pre-made solutions — lyophilised powder retains potency for years in frozen storage, while liquid preparations degrade within weeks even when refrigerated.

COA-verified · International tracking · Research grade
Research compound status for CJC-1295 means the safety evidence is drawn from animal studies, in-vitro work, and limited human observations — rather than the large-scale clinical data that informs approved drug safety. Lyophilised CJC-1295 should be stored frozen (−20°C) immediately upon receipt; repeated freeze-thaw cycles of reconstituted material should be avoided by dividing into single-dose aliquots before freezing. Bacterial endotoxin contamination is the most serious safety risk specific to research peptides — verify endotoxin testing is documented in your batch COA before any injectable research application. PubMed and bioRxiv represent the most comprehensive research databases for CJC-1295 research; prioritise peer-reviewed studies with characterised source material over unreviewed preprints or forum reports.
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 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.
