CJC-1295 research guide for Ichihara. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
The pursuit for CJC-1295 in Ichihara inevitably reaches the same conclusion: research peptides are sourced from specialist online vendors, not brick-and-mortar outlets. The core insight for Ichihara researchers: sourcing CJC-1295 comes down completely to vendor quality evaluation, not geography — and the evaluation methodology is the same regardless of where you are. Vendors worth sourcing from openly share 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. This guide gives Ichihara researchers the framework to assess vendor quality rigorously and source verified-quality CJC-1295 with confidence.
What Studies Say About 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 Ichihara comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
Buying CJC-1295: Quality Markers to Look For
Evaluating CJC-1295 vendors requires starting from the COA: access 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 establishes identity, and endotoxin levels are at acceptable levels for the intended application. For Ichihara researchers evaluating new suppliers: a small initial order to verify quality before committing to research quantities is the accepted approach among experienced researchers. Keep lyophilised CJC-1295 at −20°C 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
Research compound status for CJC-1295 means risk characterisation relies on animal studies, in-vitro work, and limited human observations — rather than the controlled trials that generate pharmaceutical safety profiles. Storage requirements for CJC-1295: lyophilised powder at minus 20°C, reconstituted solution stored refrigerated at 2-8°C and used within 30 days; reconstitute only with sterile bacteriostatic water. Verify the endotoxin level in your CJC-1295 batch COA before any injectable research application — look for results expressed as EU/mg or EU/mL and compare against acceptable research limits for your application. Researchers running multi-compound protocols with CJC-1295 should check the research literature for any reported interactions before running stacked compound experiments.
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.
