CJC-1295 research guide for Verhuny. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Verhuny 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 compete aggressively on their analytical documentation, giving researchers access to better quality signals than any physical store could provide. The primary quality indicators for CJC-1295 are HPLC purity ≥98%, molecular identity confirmed by mass spectrometry, and a bacterial endotoxin panel — all documented in a batch-matched Certificate of Analysis. Use this guide to assess sourcing options methodically — the quality evaluation approach outlined 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 Verhuny comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
CJC-1295 Purchasing Guide
Evaluating CJC-1295 vendors begins with the COA: access the batch-specific certificate before purchasing, not after. Mass spectrometry in the COA verifies that the main HPLC peak is actually CJC-1295 and not a structurally similar impurity — HPLC purity alone cannot verify molecular identity. For Verhuny researchers evaluating unfamiliar vendors: a test quantity before committing to research volumes before scaling up your order is the accepted approach among experienced researchers. Store lyophilised CJC-1295 at freezer temperature (−20°C) until ready to use; reconstitute only the amount needed for the near-term protocol and keep the remainder frozen.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not been through the clinical trial process required for pharmaceutical approval — its safety profile is characterised by preclinical data and limited human studies. 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 bacteriostatic water. Quality CJC-1295 sourcing is not separable from research safety — bacterial endotoxin contamination, incorrect identity, and breakdown products are all safety issues that proper COA verification addresses. For any individual considering CJC-1295 outside a formal research context: seek medical advice first — this compound is not approved for human use and its safety characterisation does not match that of regulated drugs.
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 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.
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.
