Power through your training with pump, energy and vascularity. NO2 Black® Muscle + 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 while you train so you can pump and feed those muscles.

  • Performance

    Nitrosigine is a N.O. Booster that 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-Ornithine 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.

    NO2 black

    Posted by Roger on 22nd Sep 2022

    I have to start out by mentioning I'm 51 yrs old. With a history of cancer and many torn muscles and ligaments throughout the years. I've been a long time user of MRI since they came out with NO2 horse sized pills back in the early 2000s. Their products work and never leave me thinking I over paid. I've been back to a regular work out regimen for the past month and this NO2 Black kicks butt. Massive pumps and a kick in the libido. Already my strength is back to when I was hitting it in my late 30s. 285 bench presses 75 pound dumbell curls 350 squats. Buy it use it share it

    I haven't received this in the mail yet but I tried the pill version back in high school. Took 1.5 bottles before life took over and I stopped working out, I loved it. Awesome they made it into a powder form. Now I'm back again more than 15 years later. Thank you MRI Performance.
