NutraBio PRE Stim-Free, as the name implies, is our stimulant free version of our PRE formula. We created PRE Stim-Free for those individuals who are sensitive to ingredients such as caffeine, hit the gym late at night, or otherwise want a pre-workout with the performance boosting ingredients found in PRE minus the stimulants. To that extent we can say PRE Stim-Free is absolutely the most thorough, effective, and purest stimulant free pre-workout in existence. PRE Stim-Free is built upon clinically dosed and scientifically backed ingredients proven to maximize workout performance and produce results.
