In the presence of sulfur dioxide and a base, iodine reacts with water in a defined stoichiometry. The titration adds iodine until water is exhausted, and the endpoint is detected electrochemically. Because the reaction is specific, other volatile components do not register as water.
Coulometric variants generate iodine electrically and suit very small water amounts.
A lyophilised peptide salt takes up moisture from air, so water content varies with handling and climate. Measuring it at release fixes the figure for the lot. For a small molecule like GHK-Cu, a few per cent water is a meaningful share of gross mass.
The figure is not stable after opening, which is why it is a release measurement.
Reported as a percentage by mass and used, with counterion content, to state how much of the vial is peptide complex. Lot documentation for GHK-Cu includes it on request.
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.
