- Before selecting a peptide for a specific research application, understand the functional differences between GHK-Cu and AHK-Cu and how those differences map to study design.
- GHK-Cu
- Lysyl oxidase activation, MMP suppression, TGF-β modulation
- Dermal fibroblasts, keratinocytes, wound models
- 7–14 days at 2–8°C
- 1–10 μM in vitro, 2–5 mM topical
- High concentrations (>50 μM) can trigger apoptosis in certain cell lines
- AHK-Cu
- VEGF receptor upregulation, Wnt/β-catenin pathway modulation
- Dermal papilla cells, hair follicles
- 5–7 days at 2–8°C
- 5–20 μM in follicle cultures
- Faster degradation in aqueous solution; less characterized mechanistically than GHK-Cu
