CJC-1295 research guide for Fundeni. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Fundeni looking to source CJC-1295, the first thing to know is that this compound is available only through an online research supply market. The upside of this online-only market is that serious vendors differentiate entirely through their analytical documentation, giving researchers better verification tools than any physical store could provide. Separating quality CJC-1295 from the rest of the market depends on three things: an HPLC chromatogram documenting ≥98% purity, mass spec data verifying the correct molecular weight, and a batch-specific endotoxin panel. This guide takes Fundeni researchers through that evaluation process and explains how to verify CJC-1295 vendor quality step by step.
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 Fundeni comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
How to Evaluate CJC-1295 Vendors
Quality CJC-1295 sourcing begins with a simple filter: does this vendor publish batch-specific COAs proactively? Those who make this data freely available are operating transparently. The HPLC analytical chromatogram is the most important document in the COA: it should show a dominant main peak representing CJC-1295, with small or absent impurity peaks representing impurities — purity should be 98% or higher. For Fundeni researchers evaluating new suppliers: a small initial order to verify quality before scaling up your order is what experienced peptide researchers consistently do. Keep lyophilised CJC-1295 at minus 20 degrees Celsius until ready to use; reconstitute only the quantity required for your immediate research and keep the remainder frozen.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not completed the clinical trial process required for pharmaceutical approval — its safety profile is characterised by preclinical data and restricted human research data. Temperature excursions — even short periods above −20°C — can partially degrade CJC-1295 without detectable changes to appearance; always use only material shipped with appropriate cold protection. Verify the endotoxin level in your CJC-1295 batch COA before any protocol involving administration — look for results reported in endotoxin units per mg or mL and confirm they fall within appropriate thresholds. The research literature on CJC-1295 should be reviewed carefully before planning any study — study approaches, dose levels, and measured endpoints vary significantly and conclusions do not uniformly extrapolate.
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.
