The Real Scoop
Transparent Labs BULK vs. The Others
Paul Sklar - Transparent Labs Athlete
“BULK is a game-changer for me.”
As you get older, and even if you’re younger, if you’re not getting a lot of sleep, you’ve got family—I’ve got 5 kids—If you’ve got all these stressors, you may lack energy before a workout.
I used to be able to get up no matter what before a workout, but as I’ve gotten older, and since I’ve tried BULK—it’s a game changer for me. The energy burst that I get is steady, and I get a phenomenal pump.
The best time to take it is about 20-30 minutes before a workout. Let it settle in, start to feel it, and you’re ready to go.
Your Questions,
Answered
What does Bulk pre-workout do?
As with most pre-workouts, Bulk is designed with your performance in mind, helping you push harder for longer in the gym. For more insights into how the Bulk Pre-Workout formula actually works, please see the ingredient overviews above.
How long does Bulk pre-workout last for?
Each container has 30 servings; for most gym-goers, that will last 30-40 workouts, depending on how large of a scoop you take.
How should Bulk be taken to maximize its effectiveness?
To maximize the effectiveness of Bulk Pre-Workout, aim to finish drinking your dose 15-30 minutes prior to your workout. This should give the product plenty of time to "kick in." In terms of how much water to drink with BULK Pre-Workout, we recommend mixing 6-10 fl. oz of water with 1/2 scoop (to assess tolerance) and mixing 12-16 fl. oz of water with 1 full scoop.
Can I take Bulk pre-workout if I'm subjected to drug testing for my sport?
Yes, absolutely. Transparent Labs Bulk Pre-Workout contains zero banned substances and is Informed Choice certified for athletes.
Why doesn't Bulk pre-workout contain creatine?
Large doses of caffeine may interfere with the ergogenic effects of creatine; since BULK Pre-Workout contains caffeine, we decided to keep the creatine separate.
What is the difference between Transparent Labs Bulk, Lean, and Stim-Free pre-workout?
Bulk is designed to support lean muscle growth and includes testosterone-supporting micronutrients, while Lean is designed to support fat loss and includes a thyroid support complex. Stim - Free, as the name suggests, contains zero stimulants and has added elevATP® for energy production.
I don't live in the United States, can I still buy Bulk?
Yes - our fulfillment center allows us to ship worldwide (with some exceptions due to fraudulent activity in certain countries; see here for more info). Standard shipping for international orders typically takes 10-14 business days to arrive.
Does this product contain nuts?
No! While Transparent Labs Bulk Pre-Workout is manufactured in a facility that processes nuts (coconuts and peanuts), we have an allergen control program that requires sanitization and cleaning of the manufacturing equipment to avoid cross-contamination of allergenic and hypoallergenic materials.
