Strom StimuMAX EXTREME
Strom StimuMAX EXTREME
Note on Texture:
This product contains high levels of hygroscopic ingredients (ingredients that naturally absorb moisture from the air). As a result, the powder may clump or harden over time.
This is a normal characteristic and does not affect the quality, potency, or effectiveness of the product. Any clumps can be easily broken apart with a fork or spoon before use.
Prepare for the EXTREME pre workout experience! Rick decided it was time for a step up from the well renowned StimuMAX Black Edition. This new blend takes your workouts to new heights with an infusion of the potent bitter orange extract. Based on the feedback from our athletes this will take your workouts to the next level and become a staple for your heavy sessions.
Don't settle for ordinary. Go Extreme.
