I’m hooked on C4. The caffeine really helps get me moving for my early morning workouts. I’m able to keep the same energy throughout my workouts and it shows.

This product really helps me in my workouts. As I have gotten older my workouts start out strong but then the intensity fades, with this product I am able to push through and finish my workout as strong as I started. Thanks!!

Great product! Taste is delicious, works wonders. Easy for beginners, may feel a tingle, but that’s normal.
