Overview

Transparent Labs PreSeries STIM-FREE V2 provides clinical doses of every ingredient without any stimulants: 8g citrulline malate, 4g beta-alanine, 2.5g betaine, 1.3g taurine, and 300mg elevATP. This makes it ideal for evening workouts, caffeine-sensitive individuals, or those who want to stack with their own caffeine source. Transparent Labs is known for their fully transparent labels with no proprietary blends, and every ingredient is dosed at or above clinical thresholds. The V2 formula added elevATP and improved the flavor system.
