Most researchers searching for CJC-1295 in Croce rapidly learn that local retail options are nearly impossible to find. What this means for Croce researchers is that geography is secondary to your ability to verify analytical documentation — and those verification methods are available to every researcher. Separating quality CJC-1295 from the rest of the market comes down to three things: an HPLC chromatogram documenting ≥98% purity, mass spec data confirming the correct molecular weight, and a batch-specific endotoxin panel. What follows is a vendor evaluation and quality guide built specifically around CJC-1295, covering everything a Croce researcher needs before placing a first order.
What Studies Say About 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 Croce researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
CJC-1295 Purchasing Guide
Before looking at individual vendors, establish a quality benchmark — so you can recognise whether a vendor meets it. Mass spectrometry in the COA establishes that the main HPLC peak is actually CJC-1295 and not a different peptide of similar polarity — HPLC purity alone does not confirm what the compound actually is. Warning signs in CJC-1295 vendor evaluation: prices significantly below market average, unclear production details, no community presence, and COAs that lack endotoxin data. For Croce researchers making a first CJC-1295 purchase: verify the vendor against this framework, start with a modest quantity, and confirm the COA batch number matches your received product before use.

COA-verified · International tracking · Research grade
CJC-1295 is supplied strictly for research applications and is not approved for human use by the FDA or equivalent regulatory bodies — all information here is provided for educational purposes. 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 bacteriostatic water. Bacterial endotoxin contamination is the most serious safety risk specific to research peptides — verify endotoxin testing is documented in your batch COA before any injectable research application. Protocol documentation — keeping clear records of compound, timing, and method — is a fundamental research principle that ensures unusual findings can be explained.
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.
