For anyone in Püski searching for CJC-1295, the first thing to know is that this compound is available only through an online research supply market. What this means for Püski researchers is that your location matters far less than your ability to assess COA data — and those evaluation tools are within reach of all serious researchers. What consistently distinguishes top CJC-1295 vendors is full COA coverage: HPLC for purity, mass spec for identity and weight verification, and endotoxin testing for safety screening. Use this guide to evaluate CJC-1295 vendors rigorously — the standards covered in this guide apply whether you are in Püski or anywhere else.
How CJC-1295 Works — Mechanisms & Research
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 Püski researchers designing GH-axis studies, compound selection based on this selectivity profile should precede protocol finalization.
How to Evaluate CJC-1295 Vendors
Evaluating CJC-1295 vendors begins with the COA: request the batch-specific certificate before placing an order, not after. Mass spectrometry in the COA verifies that the main HPLC peak is actually CJC-1295 and not a structurally similar impurity — HPLC purity alone does not confirm what the compound actually is. Signs of a credible vendor beyond COA quality: established track record of at least two years, responsive technical support who understand testing methodology, and cold chain packaging that protects product integrity. Keep lyophilised CJC-1295 at freezer temperature (−20°C) until ready to use; reconstitute only the amount needed for the near-term protocol and return unused portion to the freezer.

All use of CJC-1295 in Püski or anywhere must be research use only — this compound is not approved for human therapeutic use, and all handling should follow research laboratory protocols. Reconstitute CJC-1295 with bacteriostatic water at an appropriate concentration for your protocol; a standard 5mg reconstituted in 2mL produces 2.5mg/mL — equivalent to 25mcg per unit on an insulin syringe. 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. PubMed and bioRxiv are the primary literature resources for CJC-1295 research; prioritise peer-reviewed studies with characterised source material over unreviewed preprints or forum reports.
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 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.
