GHK-Cu

GHK-Cu does not have an approved injectable clinical dosing label. Published research and cosmetic literature most often discuss topical or experimental models, while injectable ranges are largely based on researcher-reported and practitioner-reported exploratory protocols. Researcher-reported injectable ranges commonly fall around 0.5-2.5 mg per day, with some exploratory protocols discussing 1-2 mg daily or every other day over 30-60 day research windows. These ranges should be understood as research-context references only. Protocol design depends on the study model, route, concentration, copper exposure, tissue target, and safety controls.

For storage and handling, GHK-Cu should follow standard peptide-integrity practices. Store unopened lyophilized vials refrigerated when possible and protected from direct light, heat, and repeated temperature changes. Once reconstituted, keep refrigerated and avoid unnecessary warming, freezing, or repeated agitation. If mixing is needed after adding diluent, gently swirl the vial rather than shaking it. Aggressive shaking can create foaming and may reduce peptide integrity over time.
