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.

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.
