I usually suggest that if people can do MMS1, that they do it and save CDS for those who have exteme aversions or allergies to citric acid. We are still learning the uses of CDS - MMS includes some other things, such as hypochlorus acid, and they MAY have some additional healing efficacy - remember, we did MMS for more than 10 years before CDS came along -
People have been successful with CDS, don't get me wrong, cancers have been healed, and yes herpes2 has been healed - but CDS is just the chlorine dioxide - doesn't have any of the other stuff.
Plus, if one is sexually active, the chance of reinfection is high, since so many in the population have HSV and don't know they have it (i.e., carriers, only).
I don't know what the dosing is that your son was doing at the higher doses - I'm assuming that the 1200 is actually 12000.
I don't recognize "MMSforHealth" as a supplier. It's not on the approved OR unapproved supplier list. The website is interesting, because it says CDS has no smell - ummmmm - NOT, LOL.
