Copper-binding tripeptide
GHK-Cu
Copper tripeptide-1
A naturally occurring copper-binding tripeptide studied in skin biology, extracellular-matrix signalling and cosmetic formulations.
Research interest
Skin remodelling, wound biology, hair and cosmetic formulation research, with evidence strength varying sharply by route and outcome.
Evidence lens
Known does not mean proven for everything.
The strongest claim on the page should never be stronger than the strongest source behind it.
- GHK-Cu has a larger laboratory and cosmetic literature than many online research peptides.
- Topical-formulation evidence cannot establish the safety of injection.
- FDA specifically flags injectable GHK-Cu because human safety data are limited.
- Long-term safety and meaningful clinical benefit of injectable products.
- How well small cosmetic studies generalise to marketed claims.
- Identity and contamination risk in non-regulated preparations.
- Injectable preparations may create immunogenicity and impurity concerns.
- Copper exposure, formulation and route change the risk assessment.
- Cosmetic wording should not be used to disguise a medicinal presentation.
Regulatory snapshot
Jurisdiction and context matter.
Cosmetic and medicinal presentations follow different UK rules. Verify claims and route before marketing.
FDA's safety-risk page identifies limited human data for injectable GHK-Cu; no injectable therapeutic approval is presented.
Not treated here as sporting clearance. Athletes should check the current WADA list and the exact product through Global DRO.
