Transparent Labs BULK vs. BULK BLACK Pre-Workout

Transparent Labs Bulk Pre-Workout has been a game-changer since its inception, but sports nutrition research is constantly evolving and uncovering ways to fine-tune athletic performance through supplementation. As part of our ongoing commitment to innovation, we have recently upgraded the Bulk formula to be more impactful as an industry-leading pre-workout powder. We're also bringing back the fan-favorite BULK BLACK, which flew off the shelves during the last limited batch run. 

If you've been a die-hard BULK Pre-Workout user since the beginning, you'll be glad to know the new formula revisions retain the same core of evidence-based ingredients that help you crush it in the gym. Better yet, we are ecstatic with the much-improved flavor profile (it's quite a joyride for the taste buds!).

This article will fill you in on the specific improvements made to the BULK formula and how BULK BLACK differs. 

BULK Pre-Workout Key Formula Improvements

Our goal with the original BULK formula was to craft an advanced pre-workout for athletes, bodybuilders, and gym-goers who actively strive to pack on lean muscle mass and increase strength. The new BULK formula still accomplishes that, but more effectively thanks to some fine-tuning.

The new TL BULK Pre-workout formula still packs 20+ grams of active ingredients per serving. It also remains a vegan-friendly, non-GMO product free of artificial food coloring, artificial sweeteners, preservatives, fillers, and harsh stimulants that do nothing but detract from workout performance. 

Upgrades to BULK Pre-Workout

Here's a quick break down of the improvements made in the newly revised BULK pre-workout formula:

• L-Citrulline Malate → Increased from 6,000 mg per serving to 8,000 mg to facilitate more robust blood flow and stronger pumps in the gym

• Infinergy™ Di-caffeine Malate →Upped from 30 mg per serving to 45 mg for greater  mental acuity and focus

• Astragin™ →  Now dosed at 50 mg per serving instead of 25 mg to help enhance absorption of other bioactives in BULK

• Zinc Chelate → Reduced the dose from 30 mg to 10 mg to better complement those who use other zinc-containing supplements 

• Vitamin D3 → Removed to improve formula shelf stability, flavor, and solubility

• L-Theanine → Lowered the dose from 360 mg per serving to 200 mg as the previous dose was a little too “calming” for pre-workout use.

• BCAAs → After much deliberation and research review, we decided to drop BCAAs and compensate with a larger dose of citrulline malate. This change has significantly improved the mouthfeel and taste of the formula without losing the major benefit of BCAAs before training, which is to spare muscle protein breakdown (citrulline accomplishes this on its own).

All other ingredients and doses remain the same as Bulk V2.

If you're wondering why there is no creatine in BULK, it's because we suggest taking creatine post-workout. The current body of evidence makes it clear that creatine is better absorbed after exercise (1). As such, we offer a standalone creatine monohydrate supplement with HMB.

What Is BULK BLACK?

BULK BLACK Pre-workout is a "harder-hitting" version of the original BULK formula. The major difference between the two is the additional caffeine, B vitamin, and vitamin D content in BULK BLACK. 

For gym-goers and athletes that want a stronger jolt before training, BULK BLACK is the way to go. With nearly 300 mg of caffeine per serving, BULK BLACK is sure to pack a punch and keep you dialed in for hours on end. 

Our Best-Tasting Pre-Workout Supplement Yet!

The original BULK formula made for an exceptional pre-workout, but there were some characteristics that needed refining. Notably, the flavor profile wasn't as great as we thought it could be. It was decent, but we wanted to make it a mouthwatering experience that customers can look forward to before every workout. 

After months of taste testing and fine-tuning the ingredients, we finally nailed the flavor with the new BULK formula revision and BULK BLACK. Remember, BULK and BULK BLACK are vegan-friendly pre-workouts; there are no artificial sweeteners, preservatives, or food dyes in these formulas. We use stevia and natural flavoring to create a sweet treat for the senses. 

BULK Pre-Workout comes in a variety of delicious fruit flavors, including:

1. Blue Raspberry
2. Tropical Punch
3. Orange
4. Strawberry Lemonade
5. Lemon Lime
6. Sour Grape
7. Green Apple
8. Watermelon

Meanwhile, BULK BLACK aptly comes in a black cherry flavor that is second to none. 

We stand firm on our commitment to full-label transparency. Every ingredient in our products — even the inactive natural flavoring and stevia — is listed in exact doses. The value of knowing precisely what you're getting is priceless when it comes to dietary supplements. More importantly, we want you to be confident you're not getting anything that is not on the label. 

Now that you know a little bit more about Transparent Labs BULK Pre-Workout and its iterative sibling BULK BLACK, head on over to the TL shop to grab a bottle or two. Bear in mind that BULK BLACK sold out within a day of launching last time around, so act fast!
