Acute Standardized Cutaneous Wounds (Punch-biopsy Wounds)
PepBank has 69 GHK-Cu studies with results. 41 of them gave GHK-Cu, with 226 results, grouped by what the studies measured. In each group, results from studies in people come first. Data as of 2026-10-30.

Identifiers, parent molecule, targets and development stage, from curated data.
GHK-Cu is the 1:1 complex of copper(II) with glycyl-L-histidyl-L-lysine (GHK). GSRS registers it as prezatide copper (UNII 6BJQ43T1I9, C14H22N6O4.Cu). MeSH describes the GHK tripeptide as found in human plasma. Its INCI name is copper tripeptide-1. No receptor target is established in the identity sources checked. One phase 2 trial of a topical GHK-Cu gel for skin wounds started in 2026.
No molecular target is recorded for this peptide.
Residues, differences from the parent, calculated properties and 3D structure. Source values and calculated values are shown separately.

No differences in the aligned region.
Basis: GSRS PREZATIDE COPPER has PARENT->SALT/SOLVATE relationships to PREZATIDE (39TG2H631E) and CUPRIC CATION (8CBV67279L); its active moiety is PREZATIDE.
Calculated from the two sequences with @pepdb/chem alignToParent (ungapped unless a gap scores higher). The record’s curated notes are shown as given.
Some values cannot be calculated. A modification changes this value and is not modeled here (for example a lipid, metal or linker).
