  • Arginine

    First, NO2® provides a potent dose of Arginine-AGK delivered with its clinically tested delivery technology.

  • NOS-Enhancing

    Second, the revolutionary "NOS-Enhancing" peptide fraction up-regulates nitric oxide synthase (NOS) and increases your nitric oxide levels by up to 950%.

  • Alpha-Lipoic Acid

    Third, the NO2® formula includes alpha-lipoic acid, designed to boost your insulin sensitivity and nutrient uptake. Simply put, the NO2® formula is an advanced nitric oxide generator.


Nitric oxide levels once had a pre-set limit - until NO2® that is! You see, nitric oxide (NO) generators provide your body with arginine - the building block of NO. But it's the NOS enzymes inside your body that convert the arginine into NO. In fact, NOS is the rate-limiting factor in NO production. Enter NO2®! NO2® contains ACTINOS®, the NOS-enhancing peptide fraction that's lab tested to increase NOS activity and boost nitric oxide levels by up to 950%.

As the chart depicts, regular arginine goes in and out of your system. Extended-release AAKG sustains nitric oxide levels over time. But NO2® can provide even more nitric oxide per gram of AAKG/ARG!*

In vitro research showed nutrients in MRI NO2® increased NO production in the tested cell cultures by up to 950%, which may result in a nitric oxide potential of 950%.

NO2 Pills Chart

Unleash the full potential of your workouts with MRI Performance NO2 Nitric Oxide Pills, a meticulously formulated supplement designed to enhance nitric oxide production and boost your exercise performance. The synergistic blend of key ingredients, including L-Arginine Alpha-Ketoglutarate 2:1 (A-AKG), L-Arginine HCL, Alpha-lipoic acid, ACTINOS (CFM Nitro), and Quercetin, works in harmony to maximize your athletic capabilities and promote overall cardiovascular health.

Key Ingredients and Their Synergistic Benefits

L-Arginine Alpha-Ketoglutarate 2:1 (A-AKG): A potent precursor to nitric oxide, A-AKG enhances blood flow to the muscles, promoting nutrient delivery and oxygenation. This key ingredient sets the foundation for an efficient nitric oxide boost.

L-Arginine HCL: Complementing A-AKG, L-Arginine HCL further supports nitric oxide production, leading to improved vasodilation. This enhances blood circulation, delivering more oxygen and nutrients to active muscles during exercise.

Alpha-Lipoic Acid: Known for its antioxidant properties, alpha-lipoic acid helps neutralize free radicals, supporting overall cellular health. By reducing oxidative stress, it contributes to a conducive environment for sustained nitric oxide synthesis.

ACTINOS (CFM Nitro): This innovative compound derived from whey protein isolate is scientifically proven to boost nitric oxide levels. ACTINOS works synergistically with other ingredients, enhancing the vasodilatory effect and promoting efficient nutrient delivery to muscles.

Quercetin: A flavonoid with anti-inflammatory properties, quercetin complements the nitric oxide-boosting effects by promoting cardiovascular health and aiding in recovery. Its synergistic role enhances the overall impact of the formula.

How They Work Together

Nitric Oxide Boost: A-AKG, L-Arginine HCL, and ACTINOS work in tandem to increase nitric oxide production, supporting vasodilation and improving blood flow for enhanced nutrient delivery and oxygenation.

Nitric Oxide Boost: A-AKG, L-Arginine HCL, and ACTINOS work in tandem to increase nitric oxide production, supporting vasodilation and improving blood flow for enhanced nutrient delivery and oxygenation.

Antioxidant Support: Alpha-lipoic acid and quercetin contribute antioxidant support, helping combat oxidative stress induced by intense workouts, promoting overall cellular health.

Muscle Pump and Endurance: The synergistic blend of ingredients in MRI Performance NO2 Nitric Oxide Pills results in a heightened muscle pump during workouts, leading to increased endurance and performance.

Recovery Enhancement: The combined effects of these ingredients not only improve workout performance but also aid in post-exercise recovery, ensuring you're ready for the next challenge.

    I really like this product. I instantly noticed I was more focused and had more energy throughout the day. Was able to move more weight for more reps. Was also able to do more intense cardio for longer duration. I will continue to use this product.

    I've been using this product off and on since 2002, and here we are again in 2023 with great progression using a grand product. I've been on since only March but the gains and pumps are still phenomenal! NO2 was and is my go-to! Thanks MRI!

    This is the best I've ever taken, others don't sustain the pump more then 30 minutes after your workout. I still have a pump when I go to bed. Just be sure to drink plenty of water .
