Eternal Peptides provides a lot-specific Certificate of Analysis for every KLOW Blend lot. Each COA documents component identity by HPLC and mass spectrometry, purity per component (typically ≥99%), and, where applicable, sterility and endotoxin testing, plus lot-specific storage guidance. Testing is conducted with independent laboratories including Janoshik and Finnrick Analytics, with results on the Lab Tests page.
Store unopened Klow Blend vials at 36-46°F (2-8°C) for routine laboratory storage or at -4°F (-20°C) for longer-term preservation. Keep vials tightly sealed and protected from light and moisture until required for research. When preparing a working solution, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with validated laboratory procedures. Prepared solutions are typically maintained under refrigerated or frozen conditions based on the requirements of the research protocol, with aliquoting commonly employed to help preserve blend stability by minimizing repeated freeze-thaw cycles. Always follow institutional biosafety, laboratory handling, and disposal requirements.
KLOW Blend is supplied strictly for laboratory research purposes only. It is not approved by the FDA or any regulatory authority for human use, veterinary use, clinical administration, therapeutic applications, or diagnostic procedures. Safety and efficacy in humans have not been established. The purchaser is solely responsible for compliance with all applicable laws governing the acquisition, possession, and use of research peptides, and all use must conform to institutional biosafety policies and laboratory protocols.
