Full Review
Transparent Labs BULK is what every pre-workout should aspire to be. No proprietary blends, no underdosing, no artificial junk — just science-backed ingredients at clinical doses.
Energy & Focus: The 200mg caffeine paired with L-theanine creates what many call "smooth energy." You get the alertness without the anxiety or crash. It's the perfect moderate stimulant approach.
Performance: This is where BULK truly shines. 8g of citrulline malate delivers skin-splitting pumps, while 4g of beta-alanine (full clinical dose) dramatically improves endurance. The 2.5g betaine adds a noticeable strength boost.
Transparency: The name says it all. Every single ingredient and its exact dose is listed on the label. No "proprietary energy blend" hiding underdosed ingredients.
Taste & Mixability: Flavors are solid but not as varied as some competitors. Blue Raspberry and Strawberry Lemonade are the community favorites. Mixes well but the large scoop size (due to actual clinical doses) can make it slightly gritty.
Value: At ~$1.67 per serving, it's pricier than budget options. But you're paying for clinical doses of every ingredient. Compare the actual ingredient amounts and BULK is often cheaper per gram of active ingredients than "affordable" alternatives.
The Bottom Line: Transparent Labs BULK is our top-rated pre-workout for a reason. If you want a no-compromise, science-first formula and don't mind paying a premium, this is the gold standard.

What Others Are Saying
Best pre-workout I've ever used, full stop
Mike R.
October 20, 2025
I've tried probably 15 different pre-workouts over the years and Transparent Labs BULK is the only one I keep coming back to. The 8g citrulline is the real deal — my pumps on leg day are genuinely insane. Caffeine + L-theanine combo is so smooth, zero anxiety or crash. Blue Raspberry flavor is excellent.
Switched from C4 and never going back
Taylor W.
December 18, 2025
Made the jump from C4 after 6 months of consistent training. The difference in pump quality alone is worth the extra cost. Beta-alanine at 4g keeps me pushing through the last few reps of every set. Clean label, no proprietary blends, and I can actually verify every ingredient dose. Worth every penny.
