Analysis

The powder provides 3.5 g leucine, 1.75 g isoleucine, and 1.75 g valine in a 2:1:1 ratio. Zero sugar and no listed stimulant make it suitable for use without added caffeine.

Sodium reaches 220 mg and potassium 180 mg, with a larger electrolyte blend also listed. Individual blend components and mineral forms are not shown.

The supplied package quantity is listed as only 3 grams despite 30 servings, which is internally inconsistent. Verify the container size before judging serving value or measuring expectations.

Who is it for
  • Adults wanting stimulant-free BCAAs
  • People seeking a sugar-free flavored powder
  • Users who can verify the package size
Best for
  • Intra-workout BCAA intake
  • Training recovery support
  • Stimulant-free hydration

Pros

  • Provides 7 g total BCAAs
  • Clear 2:1:1 ratio
  • No sugar
  • No listed stimulant
  • Discloses sodium and potassium

Cons

  • Package weight conflicts with serving count
  • Electrolyte blend is opaque
  • Mineral forms are unspecified
  • No complete protein

Warnings

  • Verify the package weight and serving count on the current container
  • The 220 mg sodium amount should be considered by people limiting sodium
  • Measure the powder as directed to avoid concentrating the electrolyte serving
  • People with medically restricted amino-acid intake should seek guidance

Nutrient quality

83 Highest impact

Free-form branched-chain amino acids are present in meaningful workout amounts. Undisclosed electrolyte forms and low mineral amounts limit hydration depth and broader health relevance.

.

Ingredient transparency

65 High impact

The main amino acids and elemental electrolytes have specific amounts. The electrolyte blend hides component doses, and complete directions, non-active ingredients, and mineral forms are missing.

.

Customer satisfaction

72 High impact

The aggregate rating is strong and supported by an extensive feedback volume. Specific experience details are missing, so recurring problems and purpose fit remain uncertain.

.

Value for money

75 High impact

Meaningful branched-chain amino acids support fair quality for the cost. Serving value is reasonable for a flavored workout formula.

Impact

D+ Goal FitC+ Strength of SupportC- CoverageB+ Formula Quality
Magnesium · 10 mgPotassium · 180 mg

Branched-chain amino acids and electrolytes support workout nutrition more than cellular energy. The amino-acid doses are substantial, but magnesium is tiny 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 OverallScore92
A Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB- Value

Free-form L-valine reaches a well-aligned dose and is clearly disclosed. The standard powder is convenient for workout drinks, and sport-specific certification adds assurance for tested athletes. Cost per gram is moderate rather than bulk-powder level.

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 disclosure. Its serving cost compares favorably with the collection benchmark. The label does not confirm micronization, amino acid sourcing, or independent sport certification.

Leucine · 3500 mg OverallScore79
C Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB+ Value

The label clearly discloses free-form L-leucine at a full muscle-supporting dose. Source and solubility processing are not specified, while the 11.5 g scoop is larger than the standard range used for this assessment. Cost efficiency per gram is good for the active amount supplied.
