What Is the Molecular Weight and Purity of REVIVE LAB UAE's GHK-Cu?

The ≈340 Da figure refers to the GHK tripeptide itself before the copper ion binds — since GHK-Cu is a coordination complex rather than a standalone synthesized chain, its documentation includes both the peptide backbone weight and the copper component, distinguishing it from purely peptide-only compounds elsewhere in the catalog.

HPLC purity of ≥98.0% means at least 98% of the sample by chromatographic peak area is the target GHK-Cu complex, with the remainder made up of trace synthesis byproducts. REVIVE LAB UAE documents this per production lot with a Certificate of Analysis (CoA), available on request.

GHK-Cu ships as a blue-tinted lyophilized powder — the tint confirming the copper complex is intact — for −20°C, desiccated, light-protected storage. This spec sheet describes laboratory reference-material documentation only, not a dosing chart.
