Product Details
GHK-Cu is supplied lyophilized in sealed vials for laboratory research programs, with batch-specific third-party analytical verification available for every lot.
Storage & Handling (Laboratory Reference)
Lyophilized research peptides are typically stored sealed at −20°C, protected from light and moisture, and allowed to equilibrate to room temperature before the vial is opened. Reconstituted solutions prepared with an appropriate laboratory diluent are generally kept refrigerated at 2-8°C and used within the window validated by the research protocol. Repeated freeze-thaw cycles should be avoided.
