CJC-1295 research guide for Xoloco. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
CJC-1295 won't be found on pharmacy shelves in Xoloco or virtually any local market — it's a research-grade peptide distributed through a dedicated online market. This online-only market structure is a genuine benefit for researchers — top vendors differentiate through analytical documentation in ways local stores never could. The primary quality indicators 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. Use this guide to assess sourcing options methodically — the standards covered in this guide are universal across all research contexts.
CJC-1295 Mechanisms Explained
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 Xoloco comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Source CJC-1295 — Vendor Guide
The first step for any Xoloco researcher sourcing CJC-1295 is locating suppliers that experienced researchers actively recommend — organic rankings are no guide to actual CJC-1295 quality. 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 below the threshold for research use. The combination of community reputation data and your own COA analysis is the most reliable sourcing approach — community feedback surfaces patterns individual COA review misses, and vice versa. Hold lyophilised CJC-1295 at minus 20 degrees Celsius until ready to use; reconstitute only the quantity required for your immediate research and return unused portion to the freezer.

COA-verified · International tracking · Research grade
All use of CJC-1295 in Xoloco or anywhere is research use only — this compound is not approved for human therapeutic use, and all handling should follow research laboratory protocols. Proper handling of CJC-1295 requires sterile reconstitution technique — swabbed septum with alcohol prep pad, new needle for each draw, clean preparation area — and temperature control throughout the entire workflow. Endotoxin testing in the CJC-1295 COA is absolutely required — gram-negative bacterial endotoxins can trigger dangerous immune responses at minute levels, and no cost saving makes omitting this acceptable. PubMed and bioRxiv are the primary literature resources for CJC-1295 research; favour indexed journal publications over preprints over case reports or anecdotal evidence.
Frequently Asked Questions
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.
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.
