Most researchers searching for CJC-1295 in Lebo soon discover that local retail options are all but absent from local stores. What this means for Lebo researchers is that your location matters far less than your ability to evaluate vendor quality — and those evaluation tools are accessible to anyone. Separating properly characterised CJC-1295 from the rest of the market requires three things: an HPLC chromatogram showing ≥98% purity, mass spec data establishing the correct molecular weight, and a batch-specific endotoxin panel. The sections below cover what Lebo researchers need to know about purchasing, testing, and working with CJC-1295 for legitimate research applications.
The Science Behind CJC-1295
The selectivity profile of different GHS compounds is a critical research consideration. GHRP-6 and GHRP-2 produce GH release alongside cortisol and prolactin elevation — a confounding factor in research designs where these hormones are outcome variables. Ipamorelin was specifically developed for greater GH-release selectivity with minimal cortisol and prolactin elevation, making it more suitable for research designs where GH-specific effects need to be isolated. Hexarelin has the strongest GH-releasing potency in the GHRP class but also the most significant cortisol and prolactin effects. For Lebo researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
Where to Buy CJC-1295 — A Researcher's Guide
Vetting CJC-1295 vendors requires starting from the COA: locate the batch-specific certificate before purchasing, not after. Endotoxin testing in the COA is critical for any injectable research use — endotoxins from bacterial cell wall components can trigger serious immune reactions even at trace quantities. For Lebo researchers evaluating vendors with limited track records: a modest first purchase to test the product before committing to research quantities is the accepted approach among experienced researchers. Keep lyophilised CJC-1295 at −20°C until ready to use; reconstitute only the amount needed for the near-term protocol and store the rest at −20°C.

COA-verified · International tracking · Research grade
As a research compound, CJC-1295 has not undergone the clinical trial process required for pharmaceutical approval — its safety profile is based on preclinical research and restricted human research data. Storage requirements for CJC-1295: lyophilised powder at minus 20°C, reconstituted solution refrigerated at 2-8°C and used within 30 days; reconstitute only with sterile bacteriostatic water. Bacterial endotoxin contamination is the greatest safety hazard unique to this class of compound — verify endotoxin testing is documented in your batch COA before any injectable research application. The research literature on CJC-1295 should be reviewed carefully before beginning any research — study approaches, dose levels, and measured endpoints vary significantly and results do not always generalise across models.
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.
