SCIENTIFICALLY PROVEN: We had independent PhD Scientists test GO². The results: GO² improved VO2 Max by 4% and Endurance by 6%. Oxygen is what fuels your mind and body.
BEST QUALITY: With a large breathing hole, GO² provides a seamless inhale while harnessing proven scientific principals of PEEP (Positive End Expiratory Pressure) to increase oxygen on the exhale. Hospitals have used PEEP to help people breathe better for 40 years, so you know it works! The result: improved stamina, peak performance, and clearer thinking.
