The ratio of complex to free metal and free ligand at equilibrium, usually quoted as a logarithm. A value in the high teens means the free copper concentration is vanishingly small when peptide is in excess. Published values for GHK-Cu depend on the conditions of measurement, especially pH, so a conditional constant at a stated pH is the meaningful form.
This site does not quote a single number because the literature values are condition-dependent.
The chelate effect: binding through several donors from one molecule is entropically favoured over binding several separate ligands. Three nitrogens from one tripeptide, two chelate rings, a geometry copper(II) prefers. Small peptides with a histidine near the N-terminus are among the strongest natural copper binders for exactly this reason.
Albumin binds copper through a similar N-terminal motif.
That copper cannot leave. In serum, albumin is present in vast excess; in a buffer, other chelators may be; in a blend, other peptides are. Copper distributes among all of them. A high constant means GHK competes well, not that it wins regardless.
GHK-Cu is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
