What is intermittent hypoxia exposure (HEPOX™)?
Induces controlled periods of hypoxia (reduced oxygen) to stimulate oxygen efficiency adaptations and promote red blood cell production.
Studies show results in 10-20% increase in strength and 3-5% improvement in 1000meter times.
HEPOX is designed for use during rest, at home, or while traveling.

About the founder - david greif
HEPOX™ was born from necessity. As a mechanical engineering student and aspiring pro cyclist, I hit a performance plateau that effort alone couldn’t overcome. To compete with the best, I needed the same physiological edge that many professional athletes seek— altitude adaptation. I had heard from other professionals about altitude effects on red blood cell production, but a $6,000 setup wasn’t an option (especially not one that takes over your bed). So I set out to build a better solution. I invented HEPOX™: a compact and affordable device that safely simulates high-altitude oxygen levels to trigger red blood cell production and oxygen-efficiency adaptations. The results were transformative, helping me earn a professional racing contract. Now that I am retired from professional racing, I’m bringing HEPOX to athletes everywhere—making elite-level training accessible and portable.
