Overview
GHK-Cu is a copper complex of the tripeptide glycyl-L-histidyl-L-lysine discussed in skin remodeling and wound-biology literature; mechanisms are multi-pathway and mostly preclinical or cosmetic-context.
Evidence and limitations
Human/preclinical evidence breakdown is not available in this record.
Pathways
extracellular matrix remodeling (research)
copper-peptide signaling in skin biology (research)
Interactions & cautions
Flagged in source data
unapproved injectable copper peptides stacked with other injectables
Drug interactions
high-dose copper supplements — Systemic copper load is not well quantified for many GHK-Cu products. (review)
These are observational flags for review, not individualized instructions.
