I took Zhang for 3 months and it did help me. I stunk, apparently, but couldn't smell it myself. I could lessen the smell by taking Nature's Way Chorofresh, 6 tbsp/day (the max dose). I also took some herbal supplement called Chronic Body Odor Support or something like that and that helped too. If I took a lot of both of them, then people could stand to be in the same room with me!
