Analysis

L-citrulline at 4.5 g and beta-alanine at 3.5 g provide the strongest basis for the pre-workout role. Those amounts support a performance-focused formula more convincingly than the modest electrolyte and choline additions.

Immediate caffeine anhydrous and delayed-release caffeine total 420 mg, creating a very high and potentially prolonged stimulant load. Only 50 mg of L-theanine is included, which is unlikely to offset that intensity for sensitive users.

One scoop is convenient, but the sodium and potassium amounts are too low for meaningful sweat replacement and the choline form or elemental yield is unclear. It fits highly caffeine-tolerant adults only, with careful timing and no other stimulants that day.

Who is it for
  • Highly caffeine-tolerant adults seeking an intense pre-workout
  • Experienced users who can avoid other stimulant sources
  • People prioritizing citrulline and beta-alanine
Best for
  • High-intensity training sessions
  • Long-duration stimulant effects
  • Users seeking combined citrulline and beta-alanine

Pros

  • Provides 4.5 g of L-citrulline
  • Supplies 3.5 g of beta-alanine
  • Uses immediate and delayed-release caffeine
  • Clearly states most active amounts

Cons

  • Total caffeine reaches 420 mg per serving
  • L-theanine is low relative to the stimulant load
  • Sodium and potassium are modest for workout hydration
  • The choline form and elemental yield are unclear

Warnings

  • The 420 mg caffeine total exceeds the common single-serving safety cutoff and may cause rapid heartbeat, anxiety, nausea, headache, or insomnia
  • Delayed-release caffeine can extend sleep disruption many hours after use, so avoid late-day dosing
  • Do not combine the serving with coffee, energy drinks, stimulant medicines, or other pre-workouts
  • Beta-alanine commonly causes temporary tingling or skin flushing, especially when the full scoop is taken at once

Nutrient quality

72 High impact

Caffeine anhydrous and delayed-release caffeine are specific, while the branded choline source does not disclose its chemical form. The combined caffeine load plus theobromine is unnecessarily aggressive for general use.

Ingredient transparency

80 High impact

Listed active amounts are clear without a hidden proprietary dose. Complete directions and inactive-ingredient details remain incomplete.

Customer satisfaction

70 High impact

The aggregate rating and its volume provide a limited top-level signal. Missing experience details prevent assessment of repeated complaints or purpose-specific satisfaction.

Value for money

66 High impact

Meaningful core performance doses support fair value, but the stimulant imbalance reduces quality. Meaningful core doses support some value despite important trade-offs.

Citrulline, beta-alanine, and caffeine directly support blood flow, acid buffering, work capacity, and training drive. All three core performance agents have strong human evidence when used at appropriate amounts.

Citrulline and beta-alanine are meaningfully dosed, but sodium and potassium are modest and total caffeine reaches 420 mg. Core actives and staged caffeine forms are disclosed, although the electrolyte source compounds are not named. The 420 mg total caffeine amount exceeds a prudent single-serving level and may cause marked jitteriness, heart-rate effects, or prolonged sleep disruption.

Caffeine, delayed-release caffeine, citrulline, beta-alanine, choline, theobromine, and theanine create a direct pre-workout strategy for alertness and exercise performance. Citrulline and beta-alanine reach meaningful amounts, and every active is individually disclosed.

Total caffeine reaches 420 mg in a full serving, exceeding a commonly cited daily limit for many healthy adults before other caffeine sources are counted. Theanine is only 50 mg and is unlikely to fully offset jitteriness, nausea, headache, rapid heartbeat, or prolonged sleep disruption from the stimulant load.

A substantial citrulline amount directly supports nitric-oxide production and exercise-related blood flow. Electrolytes and theanine add modest vascular and stimulant-balancing support.

The formula is a stimulant-heavy pre-workout rather than a long-term heart-health product. The combined immediate and delayed caffeine load is high and may increase heart rate, blood pressure, anxiety, or sleep disruption.

Citrulline, beta-alanine, and stimulants may increase workout capacity, focus, and training volume, indirectly supporting hypertrophy. The product provides almost no calories and no protein or creatine, so it does not address the central nutritional requirements for body-weight gain.

Citrulline and beta-alanine have meaningful amounts, but the two caffeine sources combine above the usual single-day adult limit before accounting for theobromine. The delayed-release stimulant may prolong appetite suppression or sleep disruption, which can undermine eating consistency and recovery.

Report overview
Theobromine · 100 mg OverallScore90
A+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

Standalone theobromine reaches a well-aligned amount and is clearly disclosed. Immediate and delayed-release caffeine create a high combined stimulant load, which may raise the risk of jitters, nausea, headaches, and sleep disruption in sensitive users. Serving cost is above the collection benchmark, though several substantial performance ingredients broaden the formula.

Citrulline · 4500 mg OverallScore83
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB Value

Pure L-Citrulline is named and its individual amount is disclosed. The 4,500 mg serving falls within the commonly used performance range. Good citrulline value is tempered by 300 mg caffeine plus delayed-release caffeine, which may prolong stimulation.

Theanine · 50 mg OverallScore76
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD+ Value

Clearly identified L-theanine provides a mild amount within a performance-focused stack. Immediate and delayed-release caffeine create a high combined stimulant load, so theanine may not fully offset jitters, nausea, headaches, or sleep disruption in sensitive users. The cost per active amount is high, though substantial performance ingredients improve the formula’s broader value.
