GHK-Cu

Description

GHK-Cu is a copper-binding tripeptide complex — glycyl-L-histidyl-L-lysine (Gly-His-Lys) coordinated to a copper(II) ion. Molecular formula C₁₄H₂₄N₆O₄·Cu, approximate molecular weight 403.9 g/mol, CAS 49557-75-7. It is supplied as a research-grade lyophilized powder with a characteristic blue coloration from the bound copper.

This is a lyophilized powder vial intended for laboratory research use — it is not a capsule, oral supplement, or finished consumer product.

APEX 100 supplies GHK-Cu at ≥99% HPLC-verified purity, US-sourced and independently third-party tested, with a Certificate of Analysis on file for each batch.
