Copper peptide
GHK-Cu is discussed in skincare, cosmetic, and broader peptide contexts. This page separates cosmetic discussion from medical or systemic claims.
Use precise language around topical/cosmetic context and require sources for any health claim.
Appears in consumer skincare and peptide content.
Claims vary widely by product category and route of use.
Useful as a lower-risk example of how the site separates contexts.
