Best Research Practices for GHK-Cu: Research Application Comparison
Fibroblast proliferation assays 0.1–10 μM Serum-free media to avoid copper binding by albumin Prepare fresh dilutions daily; GHK-Cu degrades in culture media within 12–16 hours at 37°C Gold standard for collagen synthesis studies but requires tight temperature

- Fibroblast proliferation assays
- 0.1–10 μM
- Serum-free media to avoid copper binding by albumin
- Prepare fresh dilutions daily; GHK-Cu degrades in culture media within 12–16 hours at 37°C
- Gold standard for collagen synthesis studies but requires tight temperature control
- Wound healing models (in vivo)
- 50–200 μM topical application
- Vehicle selection. Saline causes faster degradation than gel-based carriers
- Use immediately post-reconstitution; do not store working solutions beyond 24 hours
- Highly effective but logistically demanding due to short working solution lifespan
- Collagen gene expression studies
- 1–50 μM
- Incubation time. Effects plateau after 48 hours in most cell lines
- Aliquot and freeze; prepare working dilutions from frozen stock to maintain consistency
- Best reproducibility when using single-batch peptide source across entire study
- Antioxidant capacity assays
- 10–100 μM
- pH buffering. Activity drops sharply below pH 5.5 or above pH 8.0
- Test pH before every assay run; drift indicates degradation
- Requires rigorous pH monitoring; copper dissociation is pH-dependent
