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.

SUGGESTED USE
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.

Effective
I’ve used MRI NO2 products for years from when I was in highschool this stuff really helps with muscle pump, and endurance. I’ve never felt better while taking the product. Vasodilation is incredible perfect blood pressure. Recovery time is boosted not only with muscle soreness but also other injuries. Broke my femur while using this product the Dr said hes never seen any person heal so fast. Told him I was on a NO2 supplement, he reapplied, that made a lot of sense and had heard of it being able to help people heal faster. Ever since then I take the supplement here and there through out my life. Cycling on and off. Either way this stuff is good. And MRI is the brand I trust. I’ve used volcano and still got pumped but it didn’t feel the same to me. Didn’t have a good vibe feeling. As I do on MRI product. My honest opinion and suggestion would be to try this for at lest 3 months as with anything you won’t see full results in a month. But you’ll feel a difference the first week. You won’t be disappointed.

NO2 black
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

NO2 MUSCLE PUMP
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.
