FAQ

Premium red beetroot extract (Beta Vulgaris) with maltodextrin. Delivers naturally occurring nitrates (oxygen delivery), betaine (power output), and betalains (recovery). No stimulants, no banned substances.

Acute effects peak 2–3 hours after consumption — lower heart rate at the same output. Cumulative adaptations (VO₂ max, mitochondrial efficiency) build over 2–12 weeks of consistent use.

Full matrix preserved — we don't strip betaine and betalains like most powders. Generic beetroot powder can vary up to 10x between batches. Stamox provides consistent and measurable results. 19 years of real-world results with thousands of athletes.

The bottom line: generic beetroot is unpredictable — you can't build a serious training programme on guesswork. Stamox delivers lower heart rate, faster recovery, predictable endurance.

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.

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.

Stamox is regularly tested for anti-doping, confirming it does not contain any prohibited substance and is free from any natural contaminants.

Slightly earthy, naturally sweet. Mix with cold water and lemon. No GI distress.

Mix 1 tablespoon into 500ml water, juice, or your pre-workout. For the smoothest mix: liquid first, then powder, wait 2 minutes, stir (or use a frother). Add a splash of lemon or orange to brighten the taste and boost absorption. Also great in smoothies or yoghurt.

Mouthwash kills the oral bacteria that convert dietary nitrates intonitric oxide. Skip mouthwash, tongue scraping, and breath mints for atleast 2 hours after taking Stamox — or you'll blunt the effect.
