CUPRA
CUPRA is a proprietary two-component research blend combining two copper-coordinated tripeptides, GHK-Cu and AHK-Cu, in a fixed composition. Each component consists of a short tripeptide sequence coordinated to a single copper(II) ion, forming stable peptide–metal complexes characterized by their blue coloration. Both components are produced via solid-phase peptide synthesis (SPPS) followed by copper complexation and combined to a defined ratio. CUPRA is supplied as a lyophilized powder intended exclusively for controlled in-vitro laboratory research by qualified professionals. This product is not formulated for clinical, diagnostic, cosmetic, or therapeutic use.
