best copper. Chelated or free?? whats the opinion out there?

I use chelated, but each one has it's good points and bad points. Chelated is harder to test, but also easier to use. ionic has a tendency to bond to substrates and needs to be bare bottom. But with chelated it can also introduce undesirable EDTA (ethylenediaminetetraacetic acid.) and Ionic is easier to maintain therapeutic levels, but loses potency fast so you have to test every day.

Cupramine!! IME is the best.
