Handling & reference
- GHK-Cu — handling a copper complex, not a plain peptideGHK-Cu is a tripeptide bound to a copper(II) ion. The metal changes the mass, the colour, the light sensitivity and what a purity figure even means.
- GHK-Cu vs KPV: metal complex or plain peptideTwo small tissue-research peptides with a fundamental difference: one carries a copper ion as part of the compound, the other does not. That changes storage, colour and COA reading.
