Read the warning label!

I ordered this based on the info available on the mobile site - not sure if they show more on the desktop site, but I was shocked to see all the potential side effects of this product when I received it. We buy 2 other products from this company, and they don’t have the additional warnings (dizziness, tremors, etc.). There is no way I’ll let my son use this product. I have contacted customer service three times now to try to obtain return instructions with no response - emailed on 12/7 and 12/10, and I called on 12/23 (had to leave a message - call sent to voicemail). There’s no easy online return form like other companies offer. Awful customer service. Makes me question if I’ll buy from this company again.

Pre-workout supplements—all with virtually identical formulas—are a dime a dozen these days. 

As one of the industry’s top-selling pre-workout powders, Transparent Labs Bulk Pre-Workout has separated itself from the competition thanks to a comprehensive, evidence-based lineup of clinically dosed ingredients, fully transparent labeling, and absolutely no artificial color/food dyes, artificial sweeteners, or artificial flavoring.
 

With over 17 grams of active ingredients per scoop, BULK Pre-Workout sets the stage for you to crush it in the gym and pack on lean muscle mass by enhancing muscle strength, blood flow (muscle pumps), endurance, focus, and energy.


Key Features
 

  • Science-Based Pre-Workout Supplement for Increasing Lean Muscle Mass: BULK Pre-Workout is formulated for gym-goers and athletes who prioritize muscle-building and improved physical performance.
     
  • Enhances Strength, Stamina, and Muscle Pumps During Training: With an unmatched blend of clinically dosed nitric oxide boosters and ergogenic aids, BULK Pre-Workout fortifies athletic performance and bolsters blood flow starting from the very first scoop.
     
  • Supports Anabolic Hormone Production: The natural testosterone-supporting ingredients in BULK Pre-Workout provide lasting nutritional support for muscle growth and recovery.
     
  • Promotes Mental acuity, Focus, Drive, and Energy: Get dialed in for every workout with hard-hitting nootropics like AlphaSize® alpha-GPC, PurCaf® caffeine, L-tyrosine, and taurine. 
     
  • Naturally Flavored and 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 BULK Pre-Workout is made with natural flavoring and stevia instead of the hidden junk you find in other pre-workout formulas.
     
  • 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.
