CJC-1295 research guide for Cuyamel. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Cuyamel searching for CJC-1295, the first thing to know is that this compound is available only through an online research supply market. The practical takeaway for Cuyamel researchers: sourcing CJC-1295 depends entirely on vendor quality evaluation, not geography — and the evaluation methodology is the same regardless of where you are. Separating genuine research-grade CJC-1295 from the rest of the market requires three things: an HPLC chromatogram documenting ≥98% purity, mass spec data establishing 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 Cuyamel researcher needs to evaluate quality systematically.
The Science Behind CJC-1295
CJC-1295 belongs to the growth hormone secretagogue (GHS) class, compounds that stimulate pulsatile growth hormone release by acting on the ghrelin receptor (GHSR-1a) or growth hormone releasing hormone (GHRH) receptor. Ipamorelin, GHRP-2, GHRP-6, and Hexarelin all work primarily through GHSR-1a agonism, producing GH pulses with varying specificity profiles. CJC-1295 and Sermorelin work through the GHRH receptor, mimicking the natural hypothalamic signal for GH release. The downstream effect in both cases is increased pulsatile GH secretion and subsequent IGF-1 production in the liver. For researchers in Cuyamel studying the GH-IGF-1 axis, this mechanistic clarity makes the GHS class a productive experimental tool.
How to Source CJC-1295 — Vendor Guide
Quality CJC-1295 sourcing begins with a simple filter: does this vendor make batch-matched COAs available before purchase? Those who make this data freely available are demonstrating research-grade standards. 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. Red flags in CJC-1295 vendor evaluation: prices far under typical market pricing, unclear production details, no community presence, and COAs that lack endotoxin data. The powdered lyophilised form of CJC-1295 is always preferable to liquid pre-made solutions — lyophilised powder maintains stability for years when frozen, while liquid preparations break down rapidly even under refrigeration.

CJC-1295 is sold for research purposes only and is not approved for human therapeutic use by the FDA or equivalent regulatory bodies — all information here is provided for educational purposes. Reconstitute CJC-1295 with bacteriostatic water at an appropriate concentration for your protocol; a standard 5mg reconstituted in 2mL produces 2.5mg/mL — equivalent to 25mcg per unit on an insulin syringe. Verify the endotoxin level in your CJC-1295 batch COA before any protocol involving administration — look for results expressed as EU/mg or EU/mL and verify they are within the acceptable range for your research context. Researchers running multi-compound protocols with CJC-1295 should review the available literature for documented interactions before running stacked compound experiments.
Frequently Asked Questions
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.
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.
