    Contains 2 g; studies use 3.2–6.4 g/day. Beta-Alanine works through daily use over weeks; a lower amount still builds up, just more slowly.

Use “Check it for your dose” to see this table for your own scoops and bodyweight. Only caffeine is dosed per kilogram in the studies we cite; the other research doses are fixed amounts, so your weight doesn't change them.

How many scoops would it take?

To reach the low end of the research dose for each underdosed ingredient.

Beta-Alanine to 3.2 g
1.6 scoops
brings 320 mg caffeine
L-Citrulline to 4 g
3.3 scoops
brings 667 mg caffeine
Creatine Monohydrate to 3 g
3.9 scoops
brings 781 mg caffeine
Caffeine to 225 mg
1.1 scoops
brings 225 mg caffeine

Taking more doesn't fix this product. Reaching those doses means more than 400 mg of caffeine from the scoops alone, above the FDA's 400 mg daily reference for most adults, before any coffee.
