CJC-1295 research guide for Weidian. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Weidian 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 ranges widely across the market — from pharmaceutical-grade 99%+ purity to mislabeled or underdosed compounds — and the vendor controls every quality variable. Separating properly characterised CJC-1295 from the rest of the market depends on three things: an HPLC chromatogram confirming ≥98% purity, mass spec data confirming the correct molecular weight, and a batch-specific endotoxin panel. What follows is a sourcing and quality evaluation guide built specifically around CJC-1295, covering everything a Weidian researcher needs before placing a first order.
CJC-1295: What the Research Shows
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 Weidian comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
CJC-1295 Purchasing Guide
Evaluating CJC-1295 vendors starts with the COA: access the batch-specific certificate prior to buying, not after. The HPLC purity trace 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. Community reputation in research forums is a valuable complement to COA verification — vendors with multi-year positive track records have earned that standing through repeat quality delivery. Hold lyophilised CJC-1295 at −20°C until ready to use; reconstitute only the volume needed for upcoming use and store the rest at −20°C.

All use of CJC-1295 in Weidian or anywhere is research use only — this compound is not approved for therapeutic human application, and all handling should follow research laboratory protocols. Storage requirements for CJC-1295: lyophilised powder at freezer temperature, reconstituted solution stored refrigerated at 2-8°C and consumed within 4 weeks; reconstitute only with bac water. Verify the endotoxin level in your CJC-1295 batch COA before any protocol involving administration — look for results stated as EU/mg and verify they are within the acceptable range for your research context. PubMed are the primary literature resources for CJC-1295 research; prioritise peer-reviewed studies with characterised source material over case reports or anecdotal evidence.
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.
