2-only get your Miracle-Mineral-Supplement from an official certified seller -if you have doubts about the product,especially from one of the certified seller contact his official website and they could arrange to have it check up..
[Personally I would stay away from products sold by Global Light and their distributors..]
You can purchase sodium chlorite to make your own but it can be expensive
5-get the DVD from Adam Abraham Conversations with Jim Humble;also DR John Humiston is also interviewed-he has a clinic in Tijuana http://www.williamhittcenter.com
and he uses ti also on himself,family etc..tells why MMS can work for certain persons and not with others,etc..
