BULK Pre-Workout
BULK is one of the best-formulated and most trustworthy pre-workouts available: clinical doses, published test results and a moderate caffeine load that suits daily training. The stevia-sweetened flavors are its main weakness, so expect a stronger, less candy-like taste than mainstream brands.
Why we like it
- Clinical doses of citrulline malate (8 g), beta-alanine (4 g) and betaine (2.5 g)
- Moderate 200 mg natural caffeine paired with 200 mg L-theanine
- Informed Choice certified (per the brand) with published third-party COAs
Keep in mind
- Stevia-sweetened flavors are divisive; several reviewers call it hard to drink
- About $1.67 per serving, more than mass-market pre-workouts
