Cleavage from resin and reversed-phase purification both use trifluoroacetic acid, and the anion stays paired with basic groups through lyophilisation. It is the default counterion of a synthetic peptide unless something is done about it.
It is not inert in all cell systems at higher concentrations, which is why some laboratories specify exchange.
Passing the peptide through an exchange step replaces trifluoroacetate with acetate, a counterion closer to those found in biological systems. Exchange is not always complete and a certificate states the residual TFA where it has been done.
The salt form is part of the identity of the material as supplied.
Because it changes the mass of the solid for a given mass of peptide, and because a reader working in a sensitive system needs to know what else arrives with the compound. Lot documentation for GHK-Cu states the counterion.
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.
