"Stamox m'a permis de récupérer plus vite entre les courses et d'avoir plus de puissance au milieu de chaque effort. Je pouvais tenir une puissance maximale plus longtemps en fin de parcours — au moment où ça comptait le plus. Mon VO₂ max et ma capacité aérobie se sont améliorés. Et mentalement, je restais plus lucide et concentré, même après de longues distances."

FAQ

You would have to drink a lot of "regular" beetroot juice to achieve a good effect, and the amount you need to drink will vary enormously.

Raw beetroots and commercial juices vary wildly in active nitrate density depending on soil, season, and processing. Because their potency is never standardized or verified, your performance results will be unpredictable.

Furthermore, hitting the clinical threshold required for athletic performance via raw juice requires a massive fluid intake, often causing gastrointestinal (GI) distress before a workout.

Stamox eliminates the guesswork and the fluid load. Our extraction process delivers a precise, standardized dose of active nitrates in every scoop—guaranteeing consistent, predictable oxygen efficiency every time you train.

Stamox has a much lighter consistency and a milder, slightly sweeter flavor than standard, heavy beet powders.

For the smoothest mix, pour your water into the glass first, add the powder, let it sit for 2 minutes, and then stir (or use a handheld frother).

Taste Tip: If you want to mask the natural earthy undertones, mix Stamox with citrus juice (like lemon or orange) or blend it into your favorite fruit smoothie.

Yes, consistent daily use triggers permanent structural upgrades.

While a pre-workout dose provides immediate oxygen efficiency, daily dosing over 3+ weeks promotes mitochondrial biogenesis—meaning your body structurally builds brand-new cellular power plants to increase long-term training capacity.

The nitrate content in Stamox ranges from 1.3% to 1.7%, averaging 1.5% with a +/- 0.2% variance.

That means you're getting around 300 mg of nitrate in just two tablespoons.

However, it's crucial to understand that nitrate is only one component contributing to Stamox's unique benefits. You won't get the same results by simply taking nitrates on their own.

The true power of Stamox comes from the synergistic blend of nitrates, antioxidants and its other natural compounds working together.

  • Premium Beetroot: Sourced from the highest quality red beetroot.
  • Patented & Potent: A unique extraction ensures a stable, reliable strength in every batch.
  • Nutrient-Preserving: Processed to lock in essential micronutrients.
  • Pleasant & Versatile: A fine powder with a fresh taste for easy dosing.

Do not panic! This is a completely harmless condition called beeturia. It happens because Stamox is highly concentrated and rich in betalains—the vibrant, natural pigments found in beetroot that give it its powerful antioxidant properties. It is temporarily passing through your system and is 100% safe.

Pure red beetroot extract (Beta Vulgaris) and a trace amount of maltodextrin strictly as a technical anti-caking agent.

This is to prevent our highly concentrated active powder from absorbing airborne moisture and turning into a solid block. Stamox contains zero artificial fillers, zero sweeteners, and is anti-doping tested.

It sounds strange, but the magic actually starts on your tongue! The natural conversion of dietary nitrates into nitric oxide relies heavily on the beneficial bacteria in your mouth. Using antibacterial mouthwash or aggressive spitting within 30 minutes of taking Stamox can kill these bacteria, drastically reducing the supplement's effectiveness.
