Testimonials

"I recently started using the GO² device and felt it provided me not only a physical benefit with increased oxygen, but it also helped mentally, helping me keep my breathing steady while running."

“As soon as I saw the GO² Device I understood the science behind it and recognized the performance benefits. I've experienced a notable performance increase in training - particularly at high altitude - and look forward to extreme-testing GO² on my upcoming K2 winter expedition in Dec 2019.”

Don Bowie

"It's effective. I have high praises for it. What I've noticed is that it prevents me from hyperventilating. I used it in my Spartan race last Sunday and my time improved by 27 mins on the same course with me using the GO2."
