What is GHK-Cu?
GHK-Cu (copper tripeptide-1, CAS 89030-95-5) is a small, naturally occurring peptide first identified in human plasma. It pairs the tripeptide glycine-histidine-lysine (GHK) with a copper ion (Cu²⁺) to form a stable copper-binding complex. Thanks to this copper-transport chemistry, GHK-Cu has become one of the most widely studied peptides in skin biology, extracellular-matrix and copper-peptide research.
Aeternum Life supplies GHK-Cu as a high-purity, research-grade material — presented by its composition, content and purity, and backed by a batch-specific Certificate of Analysis.
