For anyone in Diez trying to locate CJC-1295, the key fact to understand 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 mislabeled or underdosed compounds — and the vendor controls every quality variable. A properly operating CJC-1295 supplier's COA should include HPLC purity, mass spectrometry confirmation of molecular identity, bacterial endotoxin testing, and a residual solvents panel — all traceable to your specific batch. Use this guide to verify vendor quality systematically — the framework here work regardless of your location.
The Science Behind CJC-1295
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 Diez comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
Where to Buy CJC-1295 — A Researcher's Guide
Before assessing any particular supplier, build a clear picture of what a proper COA looks like — so you can tell whether a COA is complete and credible. 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 specific to the lot you receive. Red flags in CJC-1295 vendor evaluation: prices more than 30-40% below standard market rates, no information about manufacturing source, no community presence, and COAs that lack endotoxin data. For Diez researchers making a first CJC-1295 purchase: apply these quality criteria before ordering, order conservatively at first, and verify batch traceability on arrival before use.

COA-verified · International tracking · Research grade
CJC-1295 is available for research use only and is not approved for human use by the FDA or equivalent agencies worldwide — all information here is provided for educational purposes. Lyophilised CJC-1295 should be placed in the freezer at −20°C straight away; do not freeze and thaw reconstituted CJC-1295 multiple times by preparing small aliquots before storage. Bacterial endotoxin contamination is the greatest safety hazard associated with research-grade peptides — verify endotoxin testing is documented in your batch COA before any injectable research application. PubMed 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 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.
