I can send you a sample. AC is the way to go., but not many people know how to do it. if you want true nano size particles of silver AC will do it., no nitrogen build up, just pure clear tasteless Colloidal Silver . I have excellent results from cat scratches, deep cuts and severe stomach problems., works like a charm. I will put my machine against any out there, blow the doors off. send my silver to a lab and then yours thats the real tail. game?
