Chloroquine Phosphate. We are in the same boat man. I misread another member and thought CP was Cupramine. So I started them on that only to find out they meant Chloroquine Phosphate.
You have to have a RX in order to get it. But I found a guy on eBay that gets his from Fishguy Chemicals. If you look on eBay hes the only one selling it right now. So I just put two carbon filter on my HOB to try and pull some of the copper out before I dose with CP.
