Blockhead Energy Chewing Gum with Caffeine + Vitamins 7 pieces is a cold pressed caffeine, vitamin and ginseng gum which has a number of benefits over other energy products. It is faster, acting in just 5 minutes as it works via oral absorption. It is completely sugar, calorie and now aspartame free. It\'s also the ultimate in convenience, fitting nicely into a pocket, clutch or bag and doesn\'t require liquid which take up space and increases the number of pit stops.
