Great pickup for a workout. It's not too intense, and doesn't send your heart rate through the roof like some of the others I've tried. I always end up back with C4, can't go wrong.*

I like this product.  It has less caffeine than many other pre-workouts, but, it still provides me the energy I expect.  I use this for workouts late in the day as the lower dose caffeine does not cause sleep issues for me.  I*

Bought this for the girlfriend. She says the taste is good but prefers watermelon. She takes two scoops per workout. Does not give her stomach issues. Overall good product and will buy again in different flavor. *
