| Field | Last updated |
|---|---|
| Aliases | Copper Tripeptide-1, Cu-GHK, glycyl-L-histidyl-L-lysine copper |
| Category | Healing & Repair |
| Formula | C₁₄H₂₃CuN₆O₄ |
| Molecular weight | 402.92 Da |
| Half-life | ~few minutes (plasma); used topically |
| Mechanism (summary) | GHK-Cu is the copper(II) complex of GHK and is the best-studied member of the GHK family. It is the form with the strongest mechanistic data for fibroblast activation, wound repair, and skin-remodeling biology. |
| Dosing notes | Published cell-culture work used 1 nM GHK-Cu. A cosmetic concentrate datasheet lists a solution containing 4-6% Copper Tripeptide-1 in an aqueous-glycerin base (approximately 50,000 ppm), but that is a formulation raw-material concentration rather than a clinically validated dose. No standardized systemic human research regimen was identified. |
| Storage | A current technical data sheet for a GHK Copper Tripeptide-1 concentrate recommends storage in a closed container, cool and dry, protected from humidity, with a 24-month shelf life under recommended conditions. The same sheet describes the product as water-soluble or dispersible in aqueous media. |
