We simplified the format
We Made Bicarb Topical.
2% puts sodium bicarbonate into a clean, portable stick for working muscles—nothing to mix, drink, or swallow. So your warm-up stays simple when the effort won't be.
What does this do?
Built for the moment your muscles make you back off.
2% is built to help delay the deep muscle burn that changes the effort—using sodium bicarbonate in a topical stick made for hard rides, runs, intervals, and races. Individual results vary.
The hard-effort environment
High-intensity work increases hydrogen-ion production and changes the acid–base environment around working muscle—one part of the familiar burn.
The body's buffer
Bicarbonate is one of the body's extracellular buffers. That role is why oral sodium bicarbonate has been studied extensively in high-intensity exercise.1
The topical format
2% puts sodium bicarbonate into a clean stick you roll onto the working muscles before your warm-up and hard effort.
Mixing or loading steps
Nothing to mix, swallow, or time. No pills, chalky drinks, caffeine, or loading protocol.
1 Ingredient science: Grgic et al., 2021 ISSN position stand and Lancha Junior et al., 2015 buffering review. The cited research describes bicarbonate physiology and oral sodium-bicarbonate supplementation; it does not by itself establish the effect of the finished 2% topical formula.

“First time trying this I PR’d my half marathon time by minutes. I also used it for a triathlon recently and it worked just as well.”

“I had used the stick, but it was not very portable since it leaked with any heat. I thought the tub would be better for travel. I like this product for sure.”
