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's used the GO² device and had the positive end expiratory pressure(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 two PhD physiologists All results were statistically significant.


The device

A mouthguard is often an essential piece of equipment an athlete must don before the start of a game, yet little innovation has occurred over the last 50 years. The main question is how GO² supersedes run-of-the-mill mouthguards. The differentiator for this device is how it improves lung efficiency relative to other similar devices.

  • Increases VO² Max by 4.1%*
  • Increases Endurance by 5.8%**


  • * P values of independent research < 0.001
  • ** P values of independent research < 0.005
  • P values are considered statistically significant.
  • All testing done via two cycle ergometer (Lode ®) VO² max (MGL Ultima ®) graded exercise test (GXT) performed < 1 week apart.
  • All claims of increased game performance made based on direct correlation between high intensity interval training (simulation of football) and accepted relationship to VO² max.
GO² Device for Football with Lip Guard

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%**
  • Dramatically improves heart rate recovery between plays


  • * P values of independent research < 0.001
  • ** P values of independent research < 0.005
  • P values are considered statistically significant.
  • All testing done via two cycle ergometer (Lode ®) VO² max (MGL Ultima ®) graded exercise test (GXT) performed < 1 week apart.
