GHK-CU

GHK-CU (COPPER TRIPEPTIDE-1)

A COPPER-BINDING PEPTIDE STUDIED IN COLLAGEN SIGNALLING AND TISSUE REGENERATION RESEARCH

GHK-Cu (Copper Tripeptide-1) is a naturally occurring copper-binding peptide first identified in human plasma. Interest in GHK-Cu has expanded significantly in regenerative and dermatological research as scientists explore its interaction with collagen signalling pathways, connective tissue organisation, and skin structure regulation.

The peptide forms a complex with copper ions, creating the characteristic blue copper-peptide structure frequently studied in models examining tissue remodelling, extracellular matrix signalling, and age-related changes in skin integrity.

Because copper plays an essential role in enzymatic processes linked to connective tissue stability, GHK-Cu has become one of the most widely referenced peptides in studies exploring dermal resilience and structural protein signalling.
