CJC-1295 research guide for Shercock. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
Most researchers looking for CJC-1295 in Shercock soon discover that local retail options are essentially nonexistent. The practical advantage of this online-only market is that serious vendors compete aggressively on their analytical documentation, giving researchers access to better quality signals than any physical store could provide. What genuinely separates top CJC-1295 vendors is full COA coverage: HPLC for purity, mass spec for molecular identity verification, and endotoxin testing for contamination assurance. The sections below cover what Shercock researchers need to know about purchasing, testing, and working with CJC-1295 for legitimate research applications.
CJC-1295: What the Research Shows
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 Shercock researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
CJC-1295 Purchasing Guide
The first step for any Shercock researcher sourcing CJC-1295 is finding vendors with verified community track records — organic rankings are no guide to actual CJC-1295 quality. Endotoxin testing in the COA is non-negotiable for any injectable research use — endotoxins from microbial contamination can trigger dangerous inflammatory cascades even at very low concentrations. For Shercock researchers evaluating unfamiliar vendors: a small initial order to verify quality before placing larger orders is the accepted approach among experienced researchers. The powdered lyophilised form of CJC-1295 is much more stable than liquid pre-made solutions — lyophilised powder retains potency for years in frozen storage, while liquid preparations degrade within weeks even when refrigerated.

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 comparable health authorities — all information here is provided for educational purposes. Temperature excursions — even brief warming above recommended storage temperature — can partially degrade CJC-1295 without visible changes; always use only material shipped with appropriate cold protection. The primary quality-related safety risk in CJC-1295 research is endotoxin from inadequately tested product — a confirmed endotoxin test result in the lot-matched COA is the direct mitigation for this hazard. Researchers combining CJC-1295 with other compounds should check the research literature for any reported interactions before beginning combination research.
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.
