Topical bicarbonate for performance, without GI distress.

Delivers sodium bicarbonate directly through the skin to buffer muscle acidity at the source—helping you push harder, last longer, and recover faster without the stomach issues of oral loading.

PR Lotion® is designed to support high-intensity performance and recovery by buffering acidity directly in the muscles—so you can train harder and bounce back faster.

  • Extend high-intensity performance by helping delay the buildup of muscle acidity that leads to fatigue
  • Increase power output during demanding efforts like intervals, races, or heavy lifts
  • Reduce post-workout soreness to support faster recovery between sessions
  • Train more consistently by stacking strong training days with less accumulated fatigue

PR Lotion® uses patented transdermal delivery technology to transport sodium bicarbonate through the skin and into the bloodstream—bypassing the digestive system entirely. Once absorbed, bicarbonate acts as a buffer against rising hydrogen ions (acidity) in working muscles, helping maintain optimal pH levels during high-intensity efforts.

By reducing the rate at which muscles become acidic, PR Lotion® helps delay fatigue, sustain power output, and improve overall training capacity. This localized buffering effect also supports faster recovery by minimizing the metabolic stress that contributes to post-exercise soreness.

Apply PR Lotion® liberally to working muscles 30 minutes before training or competition to allow for full absorption and effect.

  • Focus on primary muscle groups being used (legs, arms, back)
  • Use a generous amount and rub in thoroughly until absorbed
  • Effects last 5–6 hours once absorbed
  • Ideal for hard training days, races, or high-intensity sessions

Active Ingredient

Reviews Summary
Customers say this lotion helps their legs feel better during workouts and reduces soreness afterward. Many athletes use it before running, cycling, or weightlifting sessions and report less muscle fatigue during exercise. Users frequently mention improved recovery, with reduced stiffness and aches the next day. The lotion is described as easy to apply, though some note it can be difficult to rub in completely and may leave a residue on skin or clothing. A few customers question its effectiveness, with some experiencing no noticeable difference. Most find it works well for both pre-workout preparation and post-exercise recovery.

    Critical to recovery and increased frequency

    PR lotion has been instrumental in my ability to increase frequency and intensity of my workouts. Between using it and the creatine mono hydrate I’ve found a real groove that’s producing results.

    Not Bad

    After using it for a few weeks for both running and gym use I find the product does aid in slightly less soreness during the activity. The product sits on the surface layer of the skin so it doesn't absorb like normal lotion and can leave an ashy appearance. I only wish there was more product as the bottle is about half empty after less than 10 uses.

    5 years of use!

    Elderly Age Grouper Triathlete (Presently 68). I've used this product off and on for the last 5 years and there is a noticeable difference in my recovery and how I feel the day after a strenuous workout, long run, or bike ride. With PR Lotion I do not feel any of the usual morning after stiffness and aches and pains. I've experimented enough without it to appreciate the difference. No need for future experimentation!
