Legion Pulse contains even more caffeine (350mg), but what makes it the best choice for pump is the incredible levels of citrulline. At 8g per serving, you get enough citrulline to sustain healthy blood blow throughout the workout session. Citrulline is also linked to improved nitric oxide which helps with muscle pump.
Legion Pulse also stands out when it comes to pre-workouts for cardio. The reason is that it contains a whole 4.8g of beta alinine which is vital for endurance. Studies show that you need at least 1.6g of beta alinine for cardio workouts. That Legion Pulse contains 4.8g per serving makes it the obvious pick for this type of workout.
