DO NOT BUY!!!This product clearly contains some stimulant, most likely caffeine: drinking it makes me sweat and my heart beat faster. The oddly "metallic" and bitter taste is probably a reason of that. I learned the hard lesson after it messed up my circadian cycle for 2 weeks, because I usually drink it at night. YET IT'S NOT ON THE LIST OF INGREDIENTS!! I happen to be a phd student in chemistry, and I'll send it to a friend to test whether it actually contains shady things.It's hard to assume anything else than the producer's malice because they want it "performance boosting" so it appears more effective. I would disrecommend buying ANYTHING with hidden ingredients.Compared to that, its bad taste and clumping are secondary, but still.
