Mechanism and signalling
Mechanism and signalling
GHK binds copper ions with high affinity. Research examines metal homeostasis, collagen and glycosaminoglycan metabolism, and redox-sensitive pathways.
Scientific classification
Scientific classification
This profile maps GHK-Cu to the research areas regeneration, dermatology. Molecule class, evidence level, development stage and regulatory status are separated so that preclinical findings are not confused with authorised uses.
Peptides studied in models of cell migration, matrix organisation, wound healing and tissue repair.
Skin matrix, pigmentation biology, copper peptides and melanocortin signalling.
Evidence base
Clinical data
Preclinical and smaller human studies exist, especially in cosmetic dermatology. Results cannot be transferred directly to injectable or systemic use.
Regulatory status
Status varies by region
Regulatory status differs by country, product form and intended use. Authorisation in one jurisdiction does not transfer to Germany or the EU.
Safety and use notice
No dosing or administration recommendation
The available evidence does not establish safe self-directed use. This profile intentionally provides no dosing, sourcing or administration guidance.
