1. Make sure nothing you're using has vitamin C in it. Your activator or your juice.
2. When you mix your activator in with the Miracle-Mineral-Supplement and let it set for 3 minutes does it smell similar to chlorine? If not you don't have the real thing.
3. You might try using water instead of juice as your juice could have vitamin C in it.
Maybe your system isn't that contaminated and your lucky. Chlorine Dioxide is a powerful killer so keep using it for a while and it will cleanse out your system. I wouldn't take anything else with it.
