Science

Stamox increases lung capacity, blood flow and oxygen efficiency.

Stamox's high concentration of natural dietary nitrates (NO3) converts into nitric oxide (NO), a molecule that promotes vasodilation-widening blood vessels to improve oxygen-rich blood flow to muscles and organs.

Timing

For optimal results, consume Stamox about 60 to 90 minutes before the event or a workout because its effect peak within 2 to 3 hours after consumption. Stamox gives your body the nutrients needed to open up the blood vessels, making everything run more smoothly, especially during exercise.

Nitrate, Antioxidants & Natural Compounds

Rich in dietary nitrates, antioxidants and other nutrients, Stamox enhances the body's nitric oxide (NO) production; leading to improved blood flow, oxygen efficiency, and reduced fatigue. The true power of Stamox comes from the synergistic blend of nitrates, antioxidants and its other natural compounds are working together.

Potential ATP & Power Output Increase

1. ATP Production Efficiency

  • Stamox improves mitochondrial efficiency, reducing the oxygen cost of exercise by 4-5%.
  • This means the muscles generate more ATP per unit of oxygen, enhancing endurance and sustained power output.

2. Power Output (Wattage) Increase

  • Studies show an increase of 2-5% in power output during endurance exercise.
  • This equates to an increase of 5-15 watts in trained cyclists and runners.
  • Sprint performance may also improve slightly (1-3% gain).

3. Muscle Oxygenation & Performance

  • Improved muscle oxygenation leads to delayed fatigue onset and sustained ATP production.
  • VO₂ max (maximum oxygen uptake) efficiency improves, leading to longer time-to-exhaustion

Conclusion

Rich in dietary nitrates, antioxidants and other nutrients, Stamox enhances the body's nitric oxide (NO) production; leading to improved blood flow, oxygen efficiency, and reduced fatigue.

Stamox helps your body make the most of the oxygen you breathe, turning it into more usable energy for your exercise.

For athletes, drinking Stamox 2-3 hours before training or competition can result in:

  1. More efficient ATP production (4-5% oxygen efficiency improvement).
  2. 2-5% increase in power output, translating to 5-15 watts more sustained power.
  3. Delayed muscle fatigue, improving overall endurance performance.
