Analysis

The powder provides 100 mg of caffeine, which is a moderate amount for alertness or a light training session. Ten calories and 2 g of carbohydrate keep the drink relatively lean.

A 5 g amino blend is listed without individual amino identities or amounts in the supplied data. That prevents judging leucine, essential amino acid, or recovery relevance, while the small botanical extracts lack active-marker detail.

The serving cost is reasonable for a flavored energy drink but less compelling as a serious amino supplement. It suits users who want moderate caffeine and taste convenience more than precise performance dosing.

Who is it for
  • Adults seeking moderate caffeine
  • Users who want a flavored workout or productivity drink
  • People who do not need exact amino-acid dosing
Best for
  • Light energy support
  • Lower-stimulation workouts
  • A flavored alternative to coffee

Pros

  • Clearly states 100 mg of caffeine
  • Provides a moderate stimulant amount
  • Includes a 5 g amino blend
  • Has little carbohydrate
  • Offers reasonable serving cost

Cons

  • Hides individual amino acids and amounts
  • Green tea lacks EGCG standardization
  • Green coffee is included at a very small amount
  • Cannot be judged as a complete essential-amino product

Warnings

  • Caffeine may cause jitters or disturb sleep in sensitive users.
  • Avoid taking it late in the day or combining it with several other caffeine sources.
  • The undisclosed amino-blend composition should be checked for allergens or ingredients that do not fit individual needs.

Nutrient quality

61 Moderate impact

The formula names broad ingredient groups but gives little form detail for individual amino acids. The total amino blend is meaningful by weight, yet individual amino-acid doses are hidden and the botanical extracts are small.

Ingredient transparency

41 Lower impact

Caffeine and extract amounts are disclosed, but individual amino-acid quantities are hidden. Flavoring, sweeteners, and other inactive powder ingredients are not shown.

Customer satisfaction

67 High impact

The supplied aggregate rating indicates very favorable satisfaction, though no experience details are provided. No specific feedback is supplied, so recurring complaints cannot be assessed.

Value for money

65 Moderate impact

The moderate stimulant support and large amino blend provide fair value, despite limited transparency. The serving cost is reasonable for a flavored energy supplement.

The 100 mg caffeine amount provides a moderate, well-supported boost in alertness and perceived effort. A 5 g amino blend may add exercise-related support, but its individual ingredients and amounts are not disclosed.

Green tea and green coffee extracts offer little clearly separable contribution at their listed amounts. Caffeine can cause jitters or sleep disruption, so late-day use and stacking with other caffeine sources may undermine steady energy.

A moderate caffeine amount may improve alertness and attention during demanding tasks. Green tea and green coffee add related stimulant support, although their contribution appears small.

The large amino blend is not broken down into individual amounts, which makes its cognitive value difficult to judge. A 100 mg caffeine serving may still cause jitters or disturb sleep in sensitive users, especially later in the day.

A moderate caffeine amount may provide a temporary lift in alertness and energy expenditure. The green tea and green coffee amounts are too low and poorly standardized for strong added metabolic support.

Report overview
Caffeine · 100 mg OverallScore57
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

The clearly stated caffeine amount fits a moderate range for focus and exercise support. Its source and release profile are basic, with no standardized caffeine form or sustained-release technology identified. The serving costs more than the collection benchmark, and caffeine-sensitive users may experience sleep disruption if taken late in the day.

Green Tea · 50 mg OverallScore22
F Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyF Value

The small green tea extract component lacks EGCG standardization, so its anti-oxidant potency cannot be verified. No absorption-enhancing delivery system is identified, and the cost per effective EGCG amount cannot be determined. The clearly disclosed caffeine may provide stimulation but could disrupt sleep or cause jitters in caffeine-sensitive users.

83 Performance

TheanineUP Focused Energy

California Gold Nutrition
<p>It offers a clearer ingredient trade-off because 100 mg each of caffeine and L-theanine creates a balanced focus pairing, with matcha and cocoa adding mild support. It may still disrupt sleep in sensitive users and does not replace pump ingredients in a full pre-workout.</p>
84 Performance

L-Theanine & Caffeine

SR Sports Research
<p>It offers a clearer ingredient trade-off because 200 mg of L-theanine paired with 100 mg of green-coffee caffeine supports alertness with a gentler stimulant balance. It does not provide citrulline, beta-alanine, or other workout-performance ingredients.</p>
84 Performance

EGCg Green Tea Extract

Protocol For Life Balance
<p>It offers a clearer ingredient trade-off because 400 mg of decaffeinated green tea extract clearly identifies a substantial catechin and EGCG profile. It offers no stimulant energy, and high-EGCG extract may cause nausea or rare liver injury when taken fasting.</p>
87 Budget

Caffeine 200 mg

EGCg Green Tea Extract 400 mg

80 Budget

Green Tea

Jarrow Formulas

Caffeine 200 mg

84 Value

Smart Caffeine with L-Theanine

NS Natural Stacks
<p>It balances formula purpose and value because 200 mg of L-theanine paired with 100 mg of green-coffee caffeine provides practical calm-focus dosing. It has no controlled-release feature and does not supply a broader pre-workout ingredient base.</p>
74 Value

Hydroxycut Hardcore Elite

MuscleTech Performance Series
<p>It balances formula purpose and value because 270 mg of caffeine with green coffee, theanine, cocoa, coleus, and yohimbe creates strong stimulant and thermogenic effects. The aggressive combination may increase anxiety, rapid heartbeat, or blood pressure and should not be stacked with stimulants.</p>
