CJC-1295 research guide for Singair. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Singair looking to source CJC-1295, the key fact to understand is that this compound is available only through an online research supply market. What this means for Singair researchers is that geography is secondary to your ability to evaluate vendor quality — and those evaluation tools are available to every researcher. What consistently distinguishes top CJC-1295 vendors is comprehensive lot-matched testing data: HPLC for purity, mass spec for identity and weight verification, and endotoxin testing for contamination assurance. This guide walks Singair researchers through that evaluation process and explains what quality documentation for CJC-1295 should look like.
How CJC-1295 Works — Mechanisms & Research
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 Singair studying the GH-IGF-1 axis, this mechanistic clarity makes the GHS class a productive experimental tool.
Sourcing Research-Grade CJC-1295
Before looking at individual vendors, understand what genuine quality documentation contains — so you can recognise whether a vendor meets it. Endotoxin testing in the COA is non-negotiable for any injectable research use — endotoxins from gram-negative bacterial contamination can trigger severe inflammatory responses even at trace quantities. Negative indicators in CJC-1295 vendor evaluation: prices significantly below market average, vague sourcing information, no community presence, and COAs that do not include endotoxin results. Keep lyophilised CJC-1295 at freezer temperature (−20°C) until ready to use; reconstitute only the volume needed for upcoming use and keep the remainder frozen.

COA-verified · International tracking · Research grade
CJC-1295 operates outside approved pharmaceutical regulation — researchers should understand that the safety data available for CJC-1295 is based on academic studies rather than pharmaceutical approval data. Reconstitute CJC-1295 with bacteriostatic water at a concentration matched to your dosing requirements; a standard 5mg in 2mL gives a 2.5mg/mL solution — or 25mcg per insulin syringe unit. 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 using CJC-1295 alongside other research compounds should examine published studies for potential interaction data 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.
