I have used it, it does work. It will eliminate all body odor. Hair, skin, breath, even farts will not smell. However, it is not a end all be all, I totally agree with Jawbone, the only Truly effective way to not get winded is be down wind. As keen smell as deer have, it is virtually impossible to be "odor free" but chlorophyll does help.
I have a hard time believing my farts won't stink! I'll eat a pound of cabbage, 4 shots of jack Daniels, 12 oysters, 9 peanut butter crackers, a tray of broccoli, and some sushi. Then I'll ask my wife if the pills work.
