I think we need to back up for a moment and recall what the role of Miracle-Mineral-Supplement is. As I understand it, Miracle-Mineral-Supplement doesn't cure anything. It simply reduces the load on the immune system so it can recover and heal us.
I agree that a dose that is too diluted may not be effective, but my definition of too much dilution is when the free ClO2 drops below 1 PPM.
Once again, if there was 100% success with doses that had about 1 PPM, why go stronger?
