Works great, tastes terrible

This is everything I’ve been searching for in a pre-workout; a thermogenic to help me burn fat, while still giving me enough of a boost for my strength training. Plus it has low enough caffeine that I can stack it with the coffee and energy drinks I love!

That being said, the taste is TERRIBLE. I’m willing to suffer through because the workout itself is good, but the green apple tastes like you ground up apple peels, medicine, and dirt. I’ve even tried masking it by adding in some crystal light, but it doesn’t help. Just an awful taste.

Works great, and I’m old!

I switched to this after trying the Stim-Free; I was initially worried about the caffeine.

The Stim-Free had to much bete alainine (?) for me… too much tingles even at the 1/2 dose.

Lean works great giving me enough boost without the jitters. Love the Cherry Splash!

Lean Blue Raspberry

Love this pre workout, Blue raspberry is my favorite. I also use the creatine, and your Awesome Whey Protein Isolate. You have very high quality products. I will continue to use these products.

Are you tired of "cutting pre-workouts" that just don't...cut it?

If so, you've come to the right spot! Transparent Labs LEAN Pre-Workout is an evidence-based pre-workout formula featuring clinical doses of ergogenic ingredients that help you perform your best in the gym while supporting your fat-loss efforts. Experience the difference of a true cutting pre-workout formula that gets you dialed in for every training session by enhancing blood flow, strength, endurance, focus, drive, and energy production.
 

Each ingredient in this pre-workout supplement was carefully chosen based on scientific research and quality characteristics, two factors that are sadly overlooked far too often in the sports supplement realm. Like all of our products, LEAN Pre-Workout has fully transparent labeling, and absolutely no artificial color/food dyes, artificial sweeteners, or artificial flavoring.
 

Key Features
 

  • Clinically Dosed Pre-Workout for Lean Mass Retention and Fat Loss: Transparent Labs LEAN Pre-Workout is an evidence-based pre-workout that enhances athletic performance while supporting fat loss.
     
  • Improves Strength, Stamina, and Muscle Pumps During Training: With a comprehensive lineup of clinically dosed nitric oxide boosters and ergogenic aids, LEAN Pre-Workout augments athletic performance and increases blood flow to muscle tissue starting from the very first scoop.
     
  • Provides an Immediate Energy Boost with Natural Caffeine: Leave even the most intense workouts in the dust with clean nootropics like PurCaf® caffeine, theobromine, acetyl-L-carnitine, and choline bitartrate. 
     
  • Choose from 8 Refreshing All-Natural Flavors Sweetened with Stevia: Most pre-workouts come loaded with artificial colors, sweeteners, or flavors. We know you care about what you put in your body, so our goal was to make LEAN a great-tasting pre-workout with natural flavoring and stevia instead of the hidden junk you find in other caffeine-infused pre-workouts.
     
  • Third-Party Tested and Certified for Quality: As part of our commitment to industry-leading transparency and quality, every batch of this product is tested by a third-party lab for purity and potency. 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.
