i could try to imagine it but it seems a bit fantastic. extraordinary claims call for extraordinary evidence. i dont know an angstrom from a sprained ankle, but i like dr rowan as he is a champion for medical freedom. IOW, hes on our side. so the question is what were the other four major brands of CS (i use the term lightly) that he talks about being in the university study? i can imagine mesosilver, sovereign silver, those are no brainers. then i would pick advanced silver and maybe silver biotics or wellness brand. i dont think utopia made the list. it would be interesting to know.
