A chaperone binds copper and docks with its target protein, transferring the metal through a direct protein-protein interaction. At no point is there a free copper ion diffusing through the cytosol looking for a destination.
That arrangement exists because free copper is damaging. The cell solves the problem by never creating the condition — which is why the estimate usually quoted for free cytosolic copper is less than one ion per cell.
ATOX1 delivers toward the copper-transporting ATPases in the secretory pathway, which is how copper reaches enzymes destined for export, including lysyl oxidase. CCS delivers to copper-zinc superoxide dismutase. COX17 and its partners serve cytochrome c oxidase in the mitochondrion.
Each route is specific. The chaperone is not a general carrier; it is matched to its target, and that specificity is how the cell keeps a dangerous metal useful.
A peptide arriving with copper bound has to interact with a system that is already tightly organised and does not hand copper to arbitrary acceptors. Whether, and how, an exogenous copper complex enters that traffic is a genuinely open question rather than something the existence of the complex settles.
This is the kind of question a research material exists to investigate. REVIVE LAB UAE supplies GHK-Cu for laboratory research use only, with no guidance on use.
