CJC-1295 research guide for Branca. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Branca searching for CJC-1295, the foundational reality is that this compound is available only through an online research supply market. What this means for Branca researchers is that physical proximity is irrelevant compared to your ability to assess COA data — and those verification methods are accessible to anyone. The key verification criteria for CJC-1295 are HPLC purity ≥98%, molecular identity verified through mass spectrometry, and a bacterial endotoxin panel — all documented in a batch-matched Certificate of Analysis. The sections below cover what Branca researchers need to know about purchasing, testing, and working with CJC-1295 for scientific research use.
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 Branca comparing compounds in this class should account for these pharmacokinetic differences in their experimental design.
Buying CJC-1295: Quality Markers to Look For
Quality CJC-1295 sourcing begins with a straightforward question: does this vendor make batch-matched COAs available before purchase? Suppliers that publish proactively are demonstrating research-grade standards. Mass spectrometry in the COA establishes that the main HPLC peak is actually CJC-1295 and not another compound with similar chromatographic behaviour — HPLC purity alone does not confirm what the compound actually is. Signs of a credible vendor beyond COA quality: documented vendor history spanning multiple years, responsive technical support who understand testing methodology, and temperature-appropriate packaging with desiccant. Store lyophilised CJC-1295 at freezer temperature (−20°C) until ready to use; reconstitute only the quantity required for your immediate research and store the rest at −20°C.

CJC-1295 is available for research use only and is not approved for human use by the FDA or comparable health authorities — all information here is educational. Storage requirements for CJC-1295: lyophilised powder at −20°C, reconstituted solution refrigerated at 2-8°C and finished within 30 days of reconstitution; reconstitute only with bac water. Quality CJC-1295 sourcing directly determines safety outcomes — bacterial endotoxin contamination, mislabeling, and degradation products are all safety issues that rigorous vendor evaluation eliminates. PubMed and bioRxiv provide the most complete literature coverage for CJC-1295 research; focus on peer-reviewed publications with documented compound quality over conference abstracts or single case observations.
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.
