CJC-1295 research guide for Sentani. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Sentani looking to source CJC-1295, the key fact to understand is that this compound is distributed via specialist online vendors. What this means for Sentani researchers is that physical proximity is irrelevant compared to your ability to assess COA data — and those verification methods are within reach of all serious researchers. Vendors worth sourcing from proactively publish batch-matched Certificates of Analysis showing HPLC purity analysis, mass spec identity confirmation, endotoxin levels, and residual solvent results — all for the precise product run you are purchasing. What follows is a vendor evaluation and quality guide built specifically around CJC-1295, covering everything a Sentani researcher needs to evaluate quality systematically.
CJC-1295: What the Research Shows
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 Sentani researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
Where to Buy CJC-1295 — A Researcher's Guide
Before evaluating any specific vendor, build a clear picture of what a proper COA looks like — so you can identify whether a supplier meets the standard. Mass spectrometry in the COA verifies that the main HPLC peak is actually CJC-1295 and not another compound with similar chromatographic behaviour — HPLC purity alone provides no identity confirmation. For Sentani researchers evaluating unfamiliar vendors: a small initial order to verify quality before committing to research quantities is the accepted approach among experienced researchers. Store lyophilised CJC-1295 at −20°C until ready to use; reconstitute only the volume needed for upcoming use and return unused portion to the freezer.

COA-verified · International tracking · Research grade
All use of CJC-1295 in Sentani or anywhere must be research use only — this compound is not approved for human therapeutic use, and all handling should comply with standard research safety practices. Lyophilised CJC-1295 should be placed in the freezer at −20°C straight away; avoid repeatedly thawing and refreezing reconstituted peptide by aliquoting into single-use portions. Verify the endotoxin level in your CJC-1295 batch COA before any injectable research application — look for results stated as EU/mg and verify they are within the acceptable range for your research context. 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 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.
