Transparent Labs Stim-Free Pre-Workout is for gym-goers and active individuals who exercise later in the afternoon/evening and those who are sensitive to stimulants like caffeine. Alternatively, you might be taking a "stim break" and looking to cut back on caffeine. In either case, this non-stimulant pre-workout formula has you covered with an evidence-based lineup of clinically dosed ingredients, coming in at a whopping 17 grams per serving!
 

Combine that with fully transparent labeling, great flavor, and absolutely no artificial color/food dyes, artificial sweeteners, or artificial flavoring, and it's no wonder Stim-Free Pre-Workout has become a fan favorite.

Key Features

• Naturally Flavored and Sweetened with Stevia: Most non-stim pre-workouts are loaded with artificial colors, sweeteners, and flavors. We know you care about what you put in your body, so Stim-Free Pre-Workout contains only natural flavoring and stevia instead of the hidden junk you find in other pre-workout supplements.
   
• Third-Party Tested for Purity and Potency: Like all Transparent Labs products, every batch of Stim-Free Pre-Workout is third-party tested to ensure you're getting everything on the label and nothing that doesn't belong in the product.
