Each lot of GHK-Cu is accompanied by a lot-specific Certificate of Analysis. Each COA documents peptide identity by HPLC and/or mass spectrometry, verified purity, and, where applicable, sterility and endotoxin testing, plus recommended storage conditions. Testing is performed by independent third-party laboratories such as Janoshik. Each COA is traceable to a specific production lot and available on the Lab Tests page.
Store GHK-Cu as a lyophilized powder in a tightly sealed vial, protected from light and moisture. For optimal long-term stability, laboratories typically store the peptide between -20°C and -80°C, while short-term storage is generally at 2–8°C. Because GHK-Cu is a copper-peptide complex, minimizing exposure to humidity helps preserve its stability during storage. If preparation of a working solution is required, use an appropriate sterile reconstitution solution or compatible laboratory buffer in accordance with established laboratory procedures. To maintain sample integrity, researchers commonly divide prepared solutions into smaller aliquots before refrigerated or frozen storage. Always follow institutional biosafety, laboratory handling, and disposal requirements.
GHK-Cu is supplied by Eternal Peptides strictly for laboratory research use only. It is not approved for human or veterinary use, clinical administration, therapeutic intervention, or diagnostic procedures. Its safety and efficacy in humans or animals have not been established. Purchasers are solely responsible for compliance with all applicable laws, institutional biosafety requirements, and research-use policies.
