## FAQ

### What is GHK-Cu chemically?

GHK-Cu is a chelated complex of the human tripeptide glycyl-L-histidyl-L-lysine (GHK) bound to a copper(II) ion. The GHK sequence occurs naturally in human blood plasma and the compound belongs to the copper-peptide family.

### Is GHK-Cu FDA-approved for injectable use?

No. Topical GHK-Cu is used as a cosmetic ingredient without requiring FDA approval, but injectable and systemic use is not FDA-approved and is classified as investigational. Its compounding status was under active FDA review as of 2026.

### What scientific areas is GHK-Cu studied in?

GHK-Cu appears in research on collagen and extracellular-matrix biochemistry, wound-healing and tissue-remodeling models, antioxidant and anti-inflammatory pathways, dermal fibroblast biology, and cosmetic skin-firmness studies. Most evidence is in-vitro or animal-model based.
