Dosage Protocols
Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.
Protocol 1
Subcutaneous Research Protocol
Dose
1-2mg daily
Duration
4-8 weeks
Standard SC research protocol used for systemic effects on connective tissue remodeling. Rotate injection sites.
Protocol 2
Topical Research Protocol
Dose
0.05-0.2% formulation (500-2000ppm)
Duration
8-12 weeks
Matches published cosmetic and dermatology research concentrations. Applied once or twice daily to clean skin.
Protocol 3
Microdose Protocol
Dose
0.5mg SC daily or 1mg every other day
Duration
8-12 weeks
Lower-exposure variant preferred for long research cycles. Useful when stacking with other systemic compounds.
Protocol 4
Intradermal Research Protocol
Dose
0.5-1mg per session, weekly
Duration
6-10 weeks
Mesotherapy-style intradermal pattern used in some dermatologic research. Rotate sites across the target area.

Handling Notes
Lyophilized: 2-8°C preferred, -20°C for extended storage. Reconstituted: 2-8°C and use within 30 days. Protect from light — copper peptides can oxidize.
Research Considerations
Cautions
- Copper can accumulate — rotate GHK-Cu with non-copper peptides and avoid daily topical + SC stacking indefinitely.
- Always verify third-party COA for copper content and peptide purity.
- Topical research concentrations above 0.2% may cause transient irritation on sensitive skin.
