well, after the original investment it costs practically nothing. still, its something. ironfist is right about one thing - much of what is said ont he subject is a sales job.
sovereign silver is a just fine product according to those who have tried it. Utopia-Silver is also a great product and one that i can recommend because i have tried it. i personally prefer to make it myself. Colloidal Silver made with electricity is mostly ionic and works great. in fact, it is the preferred one in my book.
what ironfist is not right about is the pharmedico paradigm that has been shoved down our throats that one can be sick and then take something and it will make them well. that never happens.
