I like the energy release on this one. Other people may love the skin crawling rush and teeth gritting burst of other products. But, this one is a little different. It lasts the entire workout and helps me through the morning fatigue. I go to the gym around 5:30am and getting started is never going to be easy. But the middle to the end of the workout has become my sweet spot with this product. It won't make you want to scream out of the gate, but you will definitely have the juice to try those extra reps at the end of your sets. I recommend trying it. Both flavors that I tried were great. The tangerine is my personal favorite.
