Unfortunately, I can't really offer any useful opinions on the products you've mentioned as I have no knowledge of them myself. I've tried two different Colloidal Silver products in the past(Mesosilver and an EIS Colloidal Silver ) both of which proved to be ineffective against my particular condition(bone infection). Which stood in contrast with a colloidal solution made at home and the help of some very knowledgable people online. And more importantly, proved to be very effective against my condition.
And so that pretty much sums up the extent of my own knowledge insofar as other solutions go I'm afraid.
Having said that, I've done a great deal of research on the risks and potential effects of Colloidal Silver with regards to Argyria and other side effects and so I'd me more than happy to share my findings in hopes of helping out along the way.
