Great pre workout without the caffeine kick

It’s a great option for when I go through my biannual caffeine resensitization. Awesome product as always.

Poor customer support

I accidentally gave the wrong address and reached out to transparent labs and have not heard anything about my preworkout. It was shipped back to them and Ive tried to contact them about getting it shipped to the correct address and haven’t heard a word. Waste of money and time.

Super sour, don’t feel much effects

Taste is super sour if you don’t add a ton of water. If you get the itchiness from beta alanine you are going to hate this. I don’t mind that and I expected it but it will having you ITCHING. I just didn’t feel too many effects from this other than that. Trying to return.

TOO SWEET

Why don't you guys offered unflavored one and instead screw it with such as horrendous super sweet taste? I'm one customer who won't ever buy it again!

Great product.

I don’t like over caffeinated jittery feeling. I mix half scoop of lean and stun free for a perfect pre workout cocktail.

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.

You can find all of our test results in the footer of our website. This product is also certified by Informed Choice to meet the highest standards for athletes and consumers.
