Taste- You would never know it was sugar free, in fact it tastes better than original rockstar in my opinion! You don't get that pucker mouth feeling and it has a nice apple taste to it with a zing. More than likely the best tasting sugar free energy drink ever!
Buzz- Amazingly the twice the caffeine doesn't effect the flavor at all. And ounce for ounce this is rockstars strongest formula yet. 1000 mgs taurine, 250 mgs caffeine, 100 mgs ginseng, 100 mgs arginine, 25 mgs l-caritine, inositol and ginseng. 100% RDA vitamin b3,b5 and b6. 200% rda vitamin b2.
Total amount of mgs-1,566.4
Over all rating-9.25/10
