Twinlab Nitric Fuel is far more than a simple "pump" product, the first layer in this advanced dual-layer tablet kick-starts your workout using breakthrough fast-dissolve technology to flood muscles with cell-volumizing Nitric Oxide plus strength-enhancing Beta Alanine. The time-release second layer saturates more slowly to fuel sustained and intense 1-2 hour workouts.

Result: Pre- and post-workout "muscle pump", increased peak power and strength.

Science: Research shows that Di-Arginine Malate increases blood flow and transport of nutrients such as Beta Alanine, prized by power and endurance athletes for its role in increasing the anaerobic threshold and delaying fatigue.
