Customer Reviews

Works great before high intensity grinds

I definitely notice a difference in performance when taking ReplacesSR before a workout. Sometimes it is hard to hydrate throughout the day and get enough electrolytes into your system. This is a fast, easy way to prepare before hand. It is almost like a more direct approach to receiving the electrolytes.Combine these with a hydration drink throughout the the workout and the results are great. I have noticed less cramping, more muscular endurance and the ability to push harder during really hard grinds.
