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

The GO² Device is the only breathing device scientifically proven to increase oxygen and endurance while lowering your heartrate. The device works by applying a slight pressure on the exhale, also known as Positive End Expiratory Pressure or PEEP, a physiological technique used in healthcare for 60+ years to increase oxygen in patients. The inhale is completely natural and can be done nasally or orally.

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. This research showed an increase in VO2 Max by 4.1% and Endurance by 5.8%. You can view the research published in the esteemed Sports Medicine and Health Science Journal HERE 

To quantify these numbers, using GO² will take 10 minutes off a 4-hour marathon time (5-6 mins off a 3-hour marathon).

Designed by Doctors for use in endurance sports such as running, cycling, hiking/climbing, CrossFit, Skiing and more. Made in the USA. Go Further, Faster with GO². 

    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
    GO² Replacement Bands
    Two bands of slightly different size to give you just the right amount of PEEP to maximize performance.
