Cyclists on a podium celebrating endurance wins, boosting VO2 max with stamox beetroot sport nutrition.

380w @ 145bpm vs 153bpm

"Stamox has a massive impact on my aerobic efficiency. I can maintain a 380-watt threshold at just 145 bpm, compared to 153 bpm without it - my heart rate dropped 8 beats."


- Arvid Johannesen, Norwegian & Nordic Champion Cyclist
