Analysis

The main strength is a clearly disclosed 2:1:1 BCAA blend with 3.5 g of leucine and 1.75 g each of isoleucine and valine. Those amounts fit intra-workout amino-acid use, particularly when training takes place away from a protein-containing meal.

A 2.5 g glutamine serving adds moderate recovery-focused support, while 220 mg sodium and 180 mg potassium contribute to hydration. The sodium amount may be too light for heavy sweat losses, and the mineral forms plus the contents of the 1.14 g electrolyte blend are not identified.

The 1 g citrulline malate serving is modest for a performance ingredient, and the formula contains no stimulant for alertness. The comparatively weak serving value is a notable trade-off. It fits amino-acid intake during training better than broad energy, immunity, or heart-health goals.

Who is it for
  • People who want a flavored BCAA drink during training
  • Athletes seeking disclosed leucine, isoleucine, and valine amounts
  • Users who prefer a non-stimulant workout formula
Best for
  • Intra-workout amino-acid intake
  • Training sessions away from a protein-containing meal
  • Light hydration support during exercise

Pros

  • Provides a full 2:1:1 BCAA blend with clearly listed amounts
  • Supplies 3.5 g leucine per serving
  • Includes 2.5 g glutamine alongside the BCAAs
  • Powder format is convenient for workout drinks

Cons

  • Citrulline malate is limited to 1 g
  • Electrolyte blend ingredients and individual amounts are not disclosed
  • Sodium and potassium chemical forms are unspecified
  • Serving value is weak compared with other sizes of the same formula

Warnings

  • People following a clinician-directed sodium limit should count the 220 mg supplied per serving.
  • The potassium source is undisclosed; people following a clinician-directed potassium limit should review the full label before regular use.
  • The electrolyte blend lacks ingredient-level amounts, so combining it with other electrolyte products can make total mineral intake harder to track.

Nutrient quality

83 Highest impact

The disclosed amounts avoid an obvious excessive-dose concern. Unspecified mineral forms limit confidence in electrolyte quality.

Ingredient transparency

60 Moderate impact

Many actives have amounts, but the electrolyte blend overlaps with separately listed minerals. Flavoring, sweetener, and other inactive ingredients are not fully supplied.

Customer satisfaction

89 Highest impact

The very large review count makes the aggregate rating highly reliable. The aggregate customer rating is strong.

Value for money

63 Moderate impact

The opaque electrolyte blend adds uncertain value beside the core amino acids. The serving cost is high for an unchanged formula with modest electrolytes.

Branched-chain amino acids and electrolytes support workout nutrition more than cellular energy. Citrulline malate is well below common performance amounts, and no caffeine, creatine, or adaptogen is included.

The main amino-acid amounts are disclosed, while the electrolyte blend lacks ingredient-level doses. The product fits training recovery better than alertness or fatigue support.

Report overview
Valine · 1750 mg OverallScore72
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

Free-form L-valine is clearly disclosed at 1,750 mg, aligning well with the collection goal. The standard powder format supports convenient drink mixing, though no micronization or sport-specific certification is stated. The cost per gram is high for the amount supplied.

Isoleucine · 1750 mg OverallScore68
B+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

A fully disclosed serving supplies 1,750 mg of isolated L-isoleucine, matching the collection benchmark. The scoopable powder should be practical for mixing, although no micronization, source method, or independent testing is stated. The high serving cost weakens value despite the disclosed dose.

Leucine · 3500 mg OverallScore67
C Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

The label clearly discloses free-form L-leucine at a full muscle-supporting dose. Source and solubility processing are not specified, while the 14.5 g scoop is larger than the standard range used for this assessment. Cost efficiency per gram is poor for the active amount supplied.
