I've been taking Colloidal Silver for Hep C for ten years and it definitely keeps my viral load count low. But if I stop taking it, it shoots back up into the millions in less than a month. I have tried taking a whole bunch to see if I can eradicate it, but it starts feeling like a have a BB in my shoulder joint. It is excruciating. I tried increasing the CS several time and I get the joint pain every time. Maybe the reason I cannot take enough silver to cure hep C is because Arthritis runs in my family. My compromise is just to take a little every day.
