L-Carnitine + Taurine + L-Arginine. Monster Energy Unleaded. Our good friend Gustav who drinks Monster at odd hours has a saying, You can never get enough of a good thing. Well, for mere mortals who may be sensitive to caffeine too much may mean not falling asleep till next Tuesday or getting as nervous as a new lover before that 1st kiss. No worries, we got you covered. New Monster Unleaded has the same great original Monster taste (and we do mean grrreat!) But is formulated with a new unique energy blend to deliver a boost without caffeine. Now you can be like Gustav and go for it whenever you want!
