Fyi apagard premio has a 5-6% concentration, you ideally want 10%. That's what's been shown to be most effective in clinical trials, Apagard Royal has 10% but you can find similar concentrations cheaper from other brands.
Apagard renamel is the variation with the highest concentration but also the highest price tag.
