Re: Did you ever take Utopia Silver's Advanced Colloidal Silver?
I've never tried
Utopia-Silver personally, though I did however acquire several bottles for use in controlled experiments over the past year.
That said, here is why I believe CS manufacturing fails completely when it comes to alternative therapy. ie, When I first began researching
Colloidal Silver several years ago (Mesosilver) for my own condition. The average costs including shipping for a 500ml bottle was at/or around 65 dollars USD. Which seemed rather reasonable at the time. Or so I thought, until I discovered that I'd need as much as 2oz up to three timers per day before achieving results. However, even at 1oz, the running costs for a single month of treatment worked-out to be around $235 plus dollars, where the 2oz dose(as recommended) would have simply been absurdly expensive as a long term treatment.
Point being, the
Colloidal Silver manufacturing market simply isn't a viable option for anything but short term therapy in contrast to making ones own CS at home. Which is precisely why people come to forums like these. ie, the OP who appears to have a condition that is both long term and systematic would not likely benefit from spending thousands of dollars for manufacturing costs as opposed to spending pennies per gallon making it at home.
As for your question and comparison on efficacy, I see no point in addressing that given the vast number of people that would testify to the benefits and success of homemade CS.
