CJC-1295 research guide for Honggang. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
Most researchers trying to source CJC-1295 in Honggang rapidly learn that local retail options are all but absent from local stores. The benefit of this online-only market is that serious vendors are judged entirely by their analytical documentation, giving researchers access to better quality signals than any local market ever offers. The primary quality indicators for CJC-1295 are HPLC purity ≥98%, molecular identity verified through mass spectrometry, and a bacterial endotoxin panel — all documented in a batch-specific Certificate of Analysis. The sections below cover what Honggang researchers need to know about purchasing, testing, and working with CJC-1295 for research purposes.
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 Honggang researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
CJC-1295 Purchasing Guide
Before assessing any particular supplier, understand what genuine quality documentation contains — so you can recognise whether a vendor meets it. When reviewing a CJC-1295 COA, verify: the batch number corresponds to your vial, HPLC purity is ≥98%, mass spec confirms the correct peptide, and endotoxin levels are at acceptable levels for the intended application. The combination of peer feedback and direct document verification is the most effective quality filter — community feedback surfaces recurring issues no single purchase reveals, and vice versa. Bacteriostatic water is the standard reconstitution medium for CJC-1295 — it contains 0.9% benzyl alcohol that inhibits bacterial growth and extends reconstituted shelf life to approximately one month when stored at 2-8°C.

COA-verified · International tracking · Research grade
CJC-1295 operates outside the framework of pharmaceutical oversight — researchers should understand that the risk characterisation for this compound is based on research literature rather than clinical trials. Temperature excursions — even temporary temperature deviation — can compromise product integrity without detectable changes to appearance; always verify cold chain was maintained during shipping. Quality CJC-1295 sourcing is inseparable from safety — bacterial endotoxin contamination, incorrect identity, and breakdown products are all safety issues that verified-quality sourcing directly prevents. The research literature on CJC-1295 should be studied thoroughly before designing any protocol — study approaches, dose levels, and measured endpoints vary significantly and not all findings translate directly.
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.
