Ingredient by ingredient

Per scoop · bodyweight 75 kg (default)
  • SodiumPer scoop 130 mgStudies Not setNot gradedEvidence: Not graded

    Contains 130 mg. Not graded: on its own the sodium in a serving says little, because what counts is the drink it makes. Electrolyte products are judged on the sodium per litre once mixed as the label directs (0.5–0.7 g per litre, AIS).

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

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

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

    Contains 4 g; studies use 4–5.33 g.

  • Arginine Silicate (Nitrosigine)Label: Nitrosigine (Inositol-Stabilized Arginine Silicate)Per scoop 1.5 gStudies 1.5 gEffective doseEvidence: Weak

    Contains 1.5 g; studies use 1.5 g.

  • L-TyrosinePer scoop 1.5 gStudies Not setNot gradedEvidence: Not graded

    Contains 1.5 g. Not graded: a 2023 meta-analysis found no effect on endurance; its evidence is for focus under stress, at about 150 mg per kg of bodyweight.

  • GlycerolLabel: HydroPrime (Glycerol)Per scoop 500 mgStudies Not setNot gradedEvidence: Not graded

    Contains 500 mg. Not graded: studies used about 1–1.2 g per kg of bodyweight (75–90 g at 75 kg) with a large drink, to hold extra water before endurance exercise. Pre-workouts add 0.5–3 g of a 65% glycerol powder for "pumps"; we know of no study of amounts that small.

  • CaffeineLabel: Caffeine AnhydrousPer scoop 300 mgStudies 3–6 mg/kgEffective doseEvidence: Strong

    Contains 300 mg (4 mg/kg at 75 kg); studies use 3–6 mg/kg.

  • Caffeine, Microencapsulated [delay release]Per scoop 100 mgStudies 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.

  • TheobrominePer scoop 100 mgStudies Not setNot gradedEvidence: Not graded

    Contains 100 mg. Not graded: there is no peer-reviewed exercise trial, and 100–400 mg did not change mood or alertness in human studies.

    Not graded: we have no research dose for it from exercise studies.

  • RauwolscinePer scoop 2 mgStudies Not setNot gradedEvidence: Not graded
