GHK-Cu — compound background
Tripeptide-copper(II) complex (Gly-His-Lys : Cu²⁺)
GHK was identified by Loren Pickart in 1973 as a factor in human plasma whose concentration declines markedly with age. The decisive later finding was that its activity depends on chelated copper(II) — the peptide and the metal function as a unit. GHK-Cu is therefore a coordination complex, not simply a peptide, and it is the only such compound in this catalogue.
Solubility & reconstitution
Freely water-soluble, and unmistakable: GHK-Cu solutions are a distinct blue. That colour is the copper(II) coordination itself, which makes this the one compound here whose integrity you can partly assess by eye. A properly reconstituted vial gives a clear, evenly blue solution.
Storage
Sealed at -20 °C, dry and dark. The dry complex is stable; moisture is the main enemy. Refrigerate at 2–8 °C, protected from light. Solution pH matters unusually much here: the copper-histidine coordination weakens as pH falls, and the complex can dissociate in acidic conditions.
Commonly worked with for 2–4 weeks at 2–8 °C.
Stability
For GHK-Cu, colour is data. A solution that has gone pale, colourless, or green rather than clear blue is signalling that the coordination chemistry has changed, and no peptide-based intuition covers that.
Reading the Certificate of Analysis
Peptide purity alone is insufficient for a coordination complex. The informative figure is copper content — ideally by ICP-MS or atomic absorption — confirming the intended peptide-to-copper stoichiometry. A COA reporting only HPLC purity describes the ligand while saying nothing about whether the metal is present in the right proportion.
