Potential quality control issue

I ordered two pre-workouts, Lean Series…. Green Apple and Blue Raspberry flavors. They are closely advertised on the serving amount at 13.8 and 13.9 grams; however, TL might have a quality control issue as one of the products had a scoop with a shorter handle (serving size was as advertised - I work at a calibration lab, so I was able to weight the product after tarring an empty scoop) and the other like-item product came with a larger scoop with a longer handle. The serving for the latter was around 4 grams more.

The product is fantastic but this could be a serious issue for other users….. especially if they only order one of these and it comes with a larger than advertised serving scoop.

I bought this product after making the decision to switch over to Transparent Labs from "similar " products from other companies. I made the switch because of what I felt were superior products.

When I started using Lean, I initially started with a half scoop and increased to a full scoop within the first. I quickly noticed an improvement in my workouts. The first thing I noticed was that I felt more energized during the workout. This allows me to push a little harder. The second thing I noticed was that I didn't as "gassed" during and after my workouts.

For reference, I am a 67 years old male and I currently use 3 Transparent Labs products. I use: Lean, Creatine HMB, and Collagen Hydrolysate. I am very happy with my results and will continue using Transparent Labs products.

Love it but the flavor

I got the strawberry lemonade and the taste just wasn’t working for me, so CS was awesome and helped fix that, now trying the blue raspberry. But besides taste I love the effects.

LEAN Pre-Workout

Ever since I switched to TL products, I know I maid the correct switch. Clean, effective, and great tasting. I workout in the afternoon / early evening, one tends to get "tired" at the end of the day, but LEAN gets me "up n moving" for a solid workout every time.

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.
