Love it!

I recently gave up caffeine - but I didn't need to give up the pump!

Great product

Love the flavour; no tingles or crashes

R

The pump

I've just used it for two days and feel stronger and get the pump

Effective but too sweet for me

I like the concept behind this and it definitely improves my workout. The sweetness for me is too intense. I wish there was an unflavored or reduced stevia option.

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

  • Stimulant-Free Pre-Workout Formula Backed by Science: Ideal for those sensitive to caffeine and nighttime gym-goers, Transparent Labs Stim-Free Pre-Workout is formulated with clinically effective dosages of ergogenic ingredients to enhance your athletic performance without stimulants.

     

  • Enhances Strength, Stamina, and Muscle Pumps: With an unmatched blend of clinically dosed nitric oxide boosters, Stim-Free Pre-Workout bolsters muscle strength, endurance, and blood flow starting from the very first scoop.
     
  • Promotes Clean, Lasting Focus, Drive, and Energy: Get dialed in for every workout with evidence-based nootropics like taurine, L-tyrosine, and huperzine-A. Since this is a stimulant-free formula, it won't give you jitters or cause a post-workout crash.
     
  • 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.
