I trust the brand because my favorite tea (Yerba Mate) is sold by these folks. So now I'm a human experiment and I'm about to see if it gives me energy or does nothing or makes me weak and wired and shaky the way caffeine does. If it works, I'll surely buy a few more of these at Whole Foods and stash them for those rare occasions like this when I need it.
Soooooo....here we go. Waiting for the energy now. Waiting. Waiting. Will report back with results tomorrow.
