I've got some SuperCop 2X that's turning green - like a rusting copper pipe.
Is it still good?
Thanks! K

This can happen but does not seem to affect activity.
We looked at 5 year old green copper peptide creams and they worked just as well as new creams but did not smell as good.This message has been edited. Last edited by: Skin Biology,
