Taste-Its very close to tasting just like the real sugar free red bull but that's defiantly not a good thing. Its bland and dull tasting with the only sweetener as ace-k, which is why it tastes bad. The only some what better thing about this drink is theres a sorta creamy taste to it, but that wont make you like it any better.
Buzz-Sadly the only thing in here is not even 100% you rda. 76% RDA niacin.
Over all rating-2.25/10
