There are 2 things I look for when it comes to energy drinks - caffeine content and taste.
Most, if not all energy drinks have some caffeine content, and OKTANE has 100mg of it in one serving. The good thing about this is that it is just enough for me to get through a workout without that tingly feeling you get from other preworkouts.
The most determining factor is taste. Watermelon Kiwi is amazing, and I'm sure they will drop more and more flavors to add to their arsenal. I love this drink, it is essential for all my workouts.
Put down the redbulls, the monsters, the bangs -- OKTANE is the way to go.
