CJC-1295 research guide for Borstel. Covers DAC vs no-DAC forms, half-life differences, purity testing, and how to source quality CJC-1295 for research.
For anyone in Borstel looking to source CJC-1295, the key fact to understand is that this compound is available only through an online research supply market. The upside of this online-only market is that serious vendors differentiate entirely through their analytical documentation, giving researchers access to better quality signals than local retail ever could. What reliably differentiates top CJC-1295 vendors is complete batch-specific analytical documentation: HPLC for purity, mass spec for identity and weight verification, and endotoxin testing for contamination assurance. The sections below cover what Borstel researchers need to know about purchasing, testing, and working with CJC-1295 for research purposes.
Understanding CJC-1295 — Biology & Evidence
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 Borstel researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
How to Source CJC-1295 — Vendor Guide
Quality CJC-1295 sourcing begins with a straightforward question: does this vendor share complete COA data without being asked? Those who make this data freely available are signalling genuine quality commitment. Endotoxin testing in the COA is critical for any injectable research use — endotoxins from gram-negative bacterial contamination can trigger dangerous inflammatory cascades even at very low concentrations. Community reputation in research forums is a useful additional signal to COA verification — vendors with sustained positive community feedback have built their reputation on real product performance. The powdered lyophilised form of CJC-1295 is always preferable to liquid pre-made solutions — lyophilised powder maintains stability for years when frozen, while liquid preparations degrade within weeks even when refrigerated.

CJC-1295 is sold for research purposes only and is not approved for human consumption by the FDA or equivalent regulatory bodies — all information here is for educational purposes only. Temperature excursions — even temporary temperature deviation — can partially degrade CJC-1295 without any obvious sign; always maintain cold chain and work with cold-shipped material. Verify the endotoxin level in your CJC-1295 batch COA before any protocol involving administration — look for results stated as EU/mg and compare against acceptable research limits for your application. Protocol documentation — recording exactly what was used, when, and how — is a fundamental research principle that allows any unexpected observations to be properly contextualised.
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 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 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.
