How it works

The science

The GO² device was designed and built on proven scientific principles that have been used in healthcare for the last 40 years. 

We are the first to introduce it to the athletic/consumer space.

The device works by putting a certain amount of resistance on the exhale. The inhale is natural, the exhale has resistance (known as PEEP - positive end expiratory pressure). This is a well accepted principle that increases blood oxygen levels. Our testing proved that when an athlete uses the GO² device and the PEEP produced by the GO² device, they immediately increased their VO² max and time to exhaustion while lowering heart rate. These results were proven by independent lab tests supervised by PhD physiologists from Texas A&M University and Houston Methodist Hospital.  All results were statistically significant with P-values of <.002

GO² Device for Endurance

GO² is the world's first endurance sports device scientifically proven to increase VO2 Max by 4.1% and Endurance by 5.8%. To quantify these numbers, using GO² will take 10 minutes off a 4-hour marathon time (5-6 mins off a 3-hour marathon). In the short time it's been available, a pro triathlete has won an Ironman using GO².  

For hiking and climbing, GO² has been tested on Everest and shown to combat altitude-related shortness of breath and dramatically improve oxygen saturation.

GO² benefits are rooted in proven science by independent third-party Ph.D. researchers from Texas A&M University and Houston Methodist Hospital and proven with statistical significance.

Designed by Doctors specifically for endurance sports like running, cycling, hiking, CrossFit, and Skiing. 

Go Further, Faster with GO². 

  • Increases VO² Max by 4.1%*
  • Increases Endurance by 5.8%**
GO² Device for Football with Lip Guard and Tether

The first of its kind. A mouthguard that is scientifically proven to increase performance & endurance, allowing you to recover faster between plays, have fresher legs in the fourth quarter, and maximize your performance on every play.

  • Increases VO2 Max by 6.5%** over Battle Mouthguard. Battle mouthguards have the largest breathing aperture when compared to Nike, Vettex or LoudMouth. We tested against Battle because we felt they had the best chance of all of these brands to compete with ours, and our results blew them away. 
  • Increases Endurance (aka Time to Exhaustion) by 5.8%**
  • Improves heart rate recovery between plays
