Eternal Peptides provides a lot-specific Certificate of Analysis for every PT-141 lot. Each COA documents identity by HPLC and/or mass spectrometry, purity, and, where applicable, sterility and endotoxin levels, plus lot-specific storage guidance. Testing is conducted by independent third-party laboratories including Janoshik. COAs are batch-specific and available on the Lab Tests page.
Store lyophilized vials at 2–8°C for routine laboratory storage or below -10°C when longer-term preservation is required. Keep containers tightly sealed and protected from light and humidity to maintain peptide stability. When preparing a working solution, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with your laboratory’s established procedures. Where appropriate, laboratories may divide prepared solutions into smaller aliquots to reduce repeated freeze-thaw cycles during storage. Always handle and dispose of research materials in accordance with institutional biosafety and laboratory safety requirements.
PT-141 is supplied by Eternal Peptides strictly for laboratory research use only. It is not approved for human or veterinary use, clinical administration, therapeutic application, or diagnostic procedures of any kind. Its safety, efficacy, and pharmacological effects in humans or animals have not been established. Purchasers are solely responsible for compliance with all applicable laws, institutional biosafety standards, and research-use regulations.
