Flow Pre was designed to give you everything you need to fuel your body through those grueling workouts, intense cardio days, or any type of physically demanding work. Flow is designed for both men and women to help achieve goals and break plateaus. Flow Pre is a clinically dosed pre-workout that will give optimal vasodilation and help shuttle nutrients to the muscle tissue. This helps to combat fatigue as well as regenerate and grow muscle fibers. We use the perfect ratio of Natural Caffeine Anhydrous to give you a little extra boost without constricting blood flow.
