Awesome pump

Bulk provides a great pump without leaving you feeling jittery like some pre-workouts. It's clean and easy to digest too. 5 stars.

Amazing

I'm very sensitive to caffeine and could never use those pre-workouts. I would have terrible heart palpitations and dizziness. I tried this product and it's has been amazing! I feel the pump while taking!

Go to pre-workout. Lost lasting energy but I can still sleep that night.

Like the title said, this stuff really does all that you want a pre-workout to do. Fast acting high energy, but without the crash of high caffeine alternatives. I've found this can get be through 2+ hours or hard workouts with no issues. Better yet, I can still sleep just fine no matter how late my workout is.
In terms of flavor both the Strawberry Lemonade and Peach Mango have been spot on and tasted great. Quick warning however, both have been on the sour side, so if you don't like a more tart fruit drink then you may have to down it fast. But with as many flavors as I see them having, most likely there's an option that suits your tastebuds.

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 for Purity and Potency: Like all Transparent Labs products, every batch of Bulk Pre-Workout is third-party tested to ensure you're getting everything on the label and nothing that doesn't belong in the product.
