Analysis

L-citrulline, beta-alanine, and betaine give the formula a sensible performance base, but their amounts are modest for a demanding pre-workout. The mix is more likely to suit moderate sessions than users looking for a heavily dosed pump or endurance formula.

L-theanine and theobromine complement caffeine with a calmer, broader stimulant profile. Theanine is present at a mild amount and theobromine is better positioned as a supporting ingredient than as a strong standalone dose.

Full disclosure makes the formula easy to assess, and the multi-ingredient serving offers good practical value. However, the supplied data lists caffeine as 180 g, an implausible quantity that must be checked against the physical label before use.

Who is it for
  • Adults seeking moderate pre-workout stimulation
  • People who prefer caffeine paired with L-theanine
  • Recreational lifters who value full active-dose disclosure
Best for
  • Moderate training sessions
  • Workout energy with some calming balance
  • Budget-conscious multi-ingredient pre-workout use

Pros

  • Discloses every active amount
  • Includes gram-level citrulline, beta-alanine, and betaine
  • Pairs caffeine with L-theanine
  • Adds a clearly listed theobromine amount

Cons

  • Citrulline is modest for a pump formula
  • Beta-alanine is below many full performance servings
  • Betaine is below a typical standalone performance amount
  • No branded theanine source or purity detail is provided

Warnings

  • The supplied data lists caffeine as 180 g, which is implausible and potentially dangerous if taken literally; verify the actual unit and amount on the physical label before use.
  • Caffeine and theobromine can cause jitteriness, a faster heartbeat, or sleep disruption in stimulant-sensitive users, especially when combined with coffee or energy drinks.
  • Beta-alanine may cause temporary skin tingling or flushing, which can be uncomfortable but is usually dose related.

Nutrient quality

62 Moderate impact

Citrulline, beta-alanine, betaine, caffeine, theanine, and theobromine form a coherent pre-workout stack. Several performance amounts are moderate, while the listed caffeine unit creates an urgent dose-verification problem.

.

Ingredient transparency

68 High impact

Individual ingredient amounts are stated without a proprietary blend hiding the core formula. The implausible caffeine unit and missing flavor-system ingredients prevent dependable label interpretation.

.

Customer satisfaction

64 Moderate impact

The supplied satisfaction average is strong and has limited supporting volume. No specific experience details are provided to assess repeated complaints or alignment with the intended use.

.

Value for money

76 High impact

Multiple disclosed performance ingredients provide broad value at an accessible serving cost. Moderate core doses and the unresolved caffeine unit weaken comparison with more dependable pre-workout labels.

Report overview
Theobromine · 50 mg OverallScore89
A+ Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyB+ Value

Standalone theobromine is clearly disclosed, but the amount is better suited to sensitive users or a combined pre-workout stack than to strong theobromine-focused effects. The formula pairs it with caffeine and L-theanine, so stimulant exposure comes from more than theobromine alone. Serving cost is favorable, while the supplied details do not establish a purity percentage or identify the flavor-system excipients.

Theanine · 90 mg OverallScore76
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD+ Value

A clearly disclosed 90 mg L-theanine amount may provide mild support alongside stimulant-oriented ingredients. Generic sourcing lacks branded-form or purity assurance. Gram-level performance ingredients improve formula-level value, although theanine alone remains relatively costly.
