GHK-Cu

A copper-binding peptide used in cosmetic research and consumer skin products. That is not the same as an approved drug indication for healing or longevity.

Why it is trending: public search and clinic marketing have moved faster than a settled human evidence base. This page does not score that attention as benefit or safety.

Human evidence

Human evidence is very limited for a consumer conclusion, except where an approved labeling exists for a specific indication. This review does not invent trial results.

Preclinical evidence

Animal and laboratory papers exist for several of these compounds. Preclinical work does not establish human effectiveness.

Risks and unknowns

Known risks include an incomplete human safety picture and, outside regulated manufacturing, uncertain product identity. Major unknowns include long-term safety, standardized human dosing, and clinical effectiveness.
