AHK-Cu
Copper tripeptide-3 · Ala-His-Lys copper
GHK-Cu's less-studied sibling, used topically for hair. Almost all the research people cite for it is actually GHK-Cu research.
Storage
- Freeze-dried powder
- Finished serums at room temperature, out of direct sunlight. Raw peptide powder is best refrigerated.
- After mixing
- A finished cosmetic has a preservative system and lasts months. A serum mixed at home has none and will grow bacteria. That is the practical risk with any topical peptide.
