Greetings all from Alaska. I've been using CDS for about 2 months now, mostly for a parasite cleanse. I don't have any CLO2 test strips, but the color looks right, and the fumes are definitely potent! I'm using tablets from a company called Safrax, which claims 30 tablets dissolved in 1 liter of water = 3000 ppm. I was wondering if anyone's used this company's product before, and what their thoughts are on it? It took me several years to diagnose the parasite problem, so I'm assuming it's going to take a while to complete the protocol. Assuming the 30 tablets are producing a 3000 ppm solution, I'm currently taking 80ml per 1 liter of water, spread out over 8-10 hours, with no herx, and tolerable burning in the back of throat. Overall, no complaints at all. Thanks.
