Is ProSupps Mr. Hyde Max Pump underdosed?

• Vitamin CLabel: Vitamin C (Ascorbic Acid)Per scoop 60 mgStudies Not setNot gradedEvidence: Not graded

  Contains 60 mg. A vitamin or mineral: we grade a pre-workout’s ingredients against exercise studies; vitamins and minerals are graded only on their own supplement pages.

• L-CitrullineLabel: L-CitrulinePer scoop 4 gStudies 4–5.33 gEffective doseEvidence: Weak

  Contains 4 g; studies use 4–5.33 g.

• Beta-AlaninePer scoop 3.2 gStudies 3.2–6.4 g/dayEffective doseEvidence: Strong

  Contains 3.2 g; studies use 3.2–6.4 g/day.

• Creatine MonohydrateLabel: Creatine HClPer scoop 890 mgStudies 3–5 g/dayBelow research doseEvidence: Strong

  Contains 890 mg; studies use 3–5 g/day. Creatine Monohydrate works through daily use over weeks; a lower amount still builds up, just more slowly.

  ASSUMPTION: creatine HCl is counted as the creatine monohydrate it equals: the same 131.13 g/mol of creatine sits in 167.59 g/mol of the hydrochloride and 149.15 g/mol of the monohydrate, so 1 g = 0.89 g monohydrate. Used only when the label does not state the creatine itself.

• L-Arginine Nitrate (NO3-T)Per scoop 1 gStudies Not setNot gradedEvidence: Not graded

  Not graded: the label gives it in a form or blend we can't turn into a dose (no stated ratio or amount), so it isn't counted. See the methodology.

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.
