Pros and cons
Pre-Kaged Pre-Workout
- Informed Sport certified, with every batch tested according to Kaged
- 274 mg natural caffeine, 6.5 g L-citrulline and 2.5 g betaine per scoop
- Vegan, naturally flavored, no artificial colors and 1 g of sugar
- Solid buyer ratings (4.3 stars from about 1,100 reviews on the Krisp Apple listing)
- Only 1.6 g beta-alanine and 1.5 g creatine HCl, both below research doses
- 6.5 g of BCAAs adds bulk with little benefit if your protein intake is adequate
- About $2.25 per serving
- Very large scoop; some reviewers report stomach upset
BULK Pre-Workout
- 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
- No artificial sweeteners, colors or preservatives
- Wide flavor range (13 flavors on the brand site)
- Stevia-sweetened flavors are divisive; several reviewers call it hard to drink
- About $1.67 per serving, more than mass-market pre-workouts
- Boron and zinc "testosterone support" has weak evidence in healthy lifters
- Amazon listing carries a California Prop 65 warning for lead
Our verdicts
Pre-Kaged Pre-Workout
Pre-Kaged is one of the safest choices for tested athletes, pairing batch-level Informed Sport certification with solid caffeine, citrulline and betaine doses. Its beta-alanine and creatine fall short of research doses and the price is on the high side, so non-competitive lifters can get more per dollar elsewhere.

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.
