Don't walk, run. The stuff about ANYONE needing to take 2000ppm cs is ridiculous and untruthful at best. I have had great success using my 10-20ppm homemade ionic cs against colds, flu, bronchitis, UTI's, bladder infections, ear infections,eczema, cuts and rashes of all kinds,tooth infections and more. You don't need to buy ANY manufactured cs. Make it your self and save a fortune. The Silvergen SG6 and Silverpuppy are the tops for home cs production IMHO. You can buy a cheapy cs gen that will still make decent cs (though not as pristine as the above units) for as little as $20 and even less if you want to build your own. After that all you need is distilled water and you have all the quality cs you can drink for less than $1/gallon and it works GREAT. By the way all true Colloidal Silver
contains silver ions AND silver particles. Usually 85-95% ions and the rest silver particles. All the cs manufacturers have some hype about why their's is the only cs you should buy. Talk about hype! I for one would not drink 2000ppm cs. That is the kind of stuff that can cause agyria(if too much is taken) and is VERY metallic tasting. I love my homemade cs and so do the folks who have tried it.
