Power through your training with pump, energy and vascularity. NO2 Black® Pump is packed with S7, Nitrosigine and Hydromax to increase NO production, hydration and dilation to enhance blood flow to your muscles and fullness to your pump during your workouts.

  • Build

    Nitric Oxide opens up blood vessels and enhances nutrient delivery systems while you train so you can pump and feed those muscles.

  • Performance

    Nitrosigine increases blood flow and extends your pump so you can power through workouts with increased energy and stamina.

  • stamina

    Hydromax hyper hydrates your muscles to fuel longer workouts and increase muscle pump and fullness. L-Orthinine breaks down fatigue-promoting metabolites so you can train longer and harder.

  • stim free

    Caffeine constricts the blood vessels. Having it in an NO product is counter-productive. MRI’s NO2 BLACK PUMP is caffeine-free so you can optimize pumps without interference.


On training days, adhere to the servings below. For best results and to maximize NO2® production, take your first serving with 4-6 oz of water on an empty stomach 0-30 minutes before a workout. Consume your second serving at least 6 hours before or after your pre-workout serving. Adjust water amount to desired consistency. As NO2 Black® Muscle+Pump is highly concentrated, adhere to the below servings information.

Daily Servings

Up to 200 LBS: 1 serving (1 scoop) at least 30 minutes before eating or working out.

Over 200 LBS: 2 servings (2 scoops) at least 30 minutes before eating or working out.

    I was an original No2 fan when in HS and during my collegiate athletic career. But as my athletic career ended and my professional career away from athletics started and I began to grow my family my workouts and health took a back seat, gaining 40 lbs over the years and trying to get motivated to working out again, many other products failed me with uncomfortable jitters, or upset stomach etc, I finally decided to circle back around to MRI were I found Muscle pump and pre workout, started taking 2 weeks and have felt great since, I have a good feeling about this go around and thank MRI for the motivation and performance assistance

    N02 has done it again! I've been using their products for 15yrs, and they've never let me down. The powder tastes tremendous and pumps my muscles to their max.
