Stopped by WalMart this AM to pick up stuff and noticed this in the checkout area. 3 oz bottle with 30 cal, 7 g carb, 6 g sugar, 2000 mg Taurine and the regular 5000 mg of the "Energy Blend" containing the Guarana. Priced about the same as the big can of energy drinks, this would be a lot faster to chug down.
Caution on the bottle - "Limit intake to maximum 1 bottle every 4 hours. Do not combine with other caffeinated products."
