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 190 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 larger format also offers favorable ongoing value. 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
  • Larger format offers favorable value for frequent use

Cons

  • Citrulline malate is limited to 1 g
  • Electrolyte blend ingredients and individual amounts are not disclosed
  • Sodium and potassium chemical forms are unspecified
  • Provides little direct support for immunity or heart-health goals

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

84 Highest impact

The very large review count makes the aggregate rating highly reliable. The aggregate rating is moderate rather than leading.

Value for money

90 Highest impact

The larger supply provides excellent value per serving. The opaque electrolyte blend adds uncertain value beside the core amino acids.

Branched-chain amino acids, electrolytes, glutamine, and citrulline coherently support exercise nutrition and hydration. The disclosed amino-acid amounts are substantial, while citrulline remains below a stronger performance dose.

No caffeine, adaptogen, or mitochondrial nutrient supports alertness or general fatigue. The formula fits workout support better than broad daily energy enhancement.

Report overview
Valine · 1750 mg OverallScore84
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB- Value

Free-form L-valine reaches a well-aligned workout dose and is fully disclosed. The powder format suits mixing, though no micronization or sport-specific certification is stated. Cost efficiency is moderate for an amino-acid formula rather than bulk-powder level.

Leucine · 3500 mg OverallScore83
C Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

The fully disclosed L-leucine amount reaches the upper end of the usual muscle protein synthesis trigger range. Its source and physical processing are not identified, which limits confidence in ingredient quality and mixing performance. Strong cost efficiency per gram makes it well suited to buyers prioritizing effective leucine delivery and value.

Isoleucine · 1750 mg OverallScore80
B+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB+ Value

The powder provides a full 1,750 mg serving of isolated L-isoleucine with clear label disclosure. Its serving cost compares favorably with the collection benchmark. Source details, micronization, and independent sport testing remain unconfirmed.
