CJC-1295 research guide for Parcey. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Parcey searching for CJC-1295, the foundational reality is that this compound is available only through an online research supply market. This online-only market structure is a genuine benefit for researchers — top vendors differentiate through analytical documentation in ways brick-and-mortar outlets simply cannot. Separating genuine research-grade CJC-1295 from the rest of the market comes down to three things: an HPLC chromatogram showing ≥98% purity, mass spec data confirming the correct molecular weight, and a batch-specific endotoxin panel. Use this guide to verify vendor quality systematically — the standards covered in this guide work regardless of your location.
Understanding CJC-1295 — Biology & Evidence
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 Parcey 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 useful first test: does this vendor make batch-matched COAs available before purchase? Vendors who do are signalling genuine quality commitment. The HPLC chromatogram is the most important document in the COA: it should show a large primary peak representing CJC-1295, with negligible secondary peaks representing impurities — purity should be stated as ≥98%. For Parcey researchers evaluating new suppliers: a modest first purchase to test the product before scaling up your order is the accepted approach among experienced researchers. For Parcey researchers making a first CJC-1295 purchase: apply these quality criteria before ordering, start with a modest quantity, and confirm the COA batch number matches your received product before use.

CJC-1295 is supplied strictly for research applications and is not approved for human consumption by the FDA or comparable health authorities — all information here is for educational purposes only. Reconstitute CJC-1295 with bacteriostatic water at the concentration suited to your research design; a standard 5mg in 2mL gives a 2.5mg/mL solution — providing 25mcg per unit measured on a 100-unit syringe. Verify the endotoxin level in your CJC-1295 batch COA before any injectable research application — look for results stated as EU/mg and confirm they fall within appropriate thresholds. 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.
