We believe that the best version of ourselves starts with proper hydration

Made by Athletes For Athletes

While sitting in the locker room in 2013, college athletes and Cirkul co-founders Garrett and Andy found themselves frustrated with the available flavored water options. They valued hydration and knew that electrolyte replenishment was critical to their performance. Not willing to sacrifice taste, they knew they could create a better way to hydrate that was tastier, healthier, and more reliable than the inconsistent and messy powder or the abundance of sugar they were struggling with.

Out of that desire, the Cirkul system was born. Their water bottle and flavor cartridge system adds just the amount of flavor you want in any given sip. Stage Hydration goes beyond flavor and offers the ultimate electrolyte hydration tool for athletes that want efficiency, flexibility, and convenience.

“Gatorade Treats Everyone the Same, Stage Caters it to You”

If anyone can say this with confidence it’s Bob Murray, PhD FASCM, who co-founded and directed the Gatorade Sports Institute for 23 years. Working with elite athletes on the forefront of exercise science and hydration research, Bob is the first to believe that the “number of electrolytes people need is trial and error” but once “athletes feel the benefits of staying hydrated” they will maximize their potential.

Stage Hydration Endurance Formula is the result of over 30 years of exploring the science of hydration. Dr. Murray and Stage Hydration are committed to helping you accomplish those hydration goals, feel that difference, and ultimately feel your best.
