Analysis

Glycerol powder provides the largest serving component and supports workout hydration and pump. Three grams of L-citrulline, one gram of arginine hydrochloride, and 500 mg agmatine build a logical nitric-oxide pathway.

The amounts can support a moderate pump but do not match more concentrated standalone formulas. Betaine at 500 mg is a minor addition rather than a full performance serving, and the formula lacks creatine or meaningful calories for direct mass gain.

Most actives are individually disclosed and the stimulant-free design suits late training better than caffeine-heavy products. PeakO2 is listed only as a blend, so its mushroom components and their individual amounts cannot be assessed.

Who is it for
  • Adults seeking a stimulant-free pre-workout
  • Late-day trainees who want pump support
  • Users prioritizing hydration and blood-flow ingredients
Best for
  • Moderate workout pumps
  • Stimulant-free training
  • Hydration-focused sessions

Pros

  • Provides 3.5 g glycerol powder
  • Includes 3 g L-citrulline
  • Combines arginine and agmatine
  • Avoids caffeine
  • Discloses most active amounts

Cons

  • Citrulline is below stronger pump servings
  • Betaine is lightly dosed
  • PeakO2 component amounts are hidden
  • Lacks creatine or a direct mass-building foundation

Warnings

  • Citrulline, arginine, and agmatine may add to blood-pressure-lowering effects from nitrates or antihypertensive medicines.
  • The 3.5 g glycerol-powder amount can cause headache or digestive discomfort if fluid intake is inadequate.
  • Arginine and citrulline can cause stomach upset in sensitive users, especially when taken close to intense exercise.
  • PeakO2 blend components are not identified in the supplied data, limiting allergy and intolerance screening.

Nutrient quality

79 High impact

The main pump ingredients use recognizable forms and cover hydration and nitric-oxide pathways. Moderate citrulline and arginine amounts, low betaine, and an opaque blend limit performance depth.

.

Ingredient transparency

60 Moderate impact

Most actives have individual amounts and specific chemical forms. The PeakO2 blend hides its components, while other ingredients and complete directions are missing.

.

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

65 Moderate impact

Several useful pump ingredients provide broad training value within one serving. Moderate core doses and an opaque blend make the premium serving cost less compelling.

Three grams of L-citrulline and 1 gram of arginine hydrochloride provide direct nitric-oxide support for blood flow. The amounts are useful but below the depth of stronger standalone citrulline formulas.

Both vasodilator doses are disclosed and the powder offers straightforward delivery. Citrulline and arginine can add to the blood-pressure-lowering effects of nitrates or antihypertensive medicines.

Citrulline · 3000 mg

Citrulline and arginine create a credible nitric-oxide pathway for blood-flow support. The formula remains an exercise pump product and does not cover lipid, cardiac-energy, or homocysteine needs.

The citrulline amount is useful but sits below many full-dose performance formulas. Agmatine and glycerol support the intended exercise function, while the proprietary mushroom blend is less transparent.

Citrulline, glycerol, arginine, agmatine, and betaine target blood flow and workout hydration rather than mental energy. The formula is stimulant-free and fully discloses most amounts.

Citrulline · 3000 mg

Citrulline, glycerol, arginine, and agmatine may improve blood flow, hydration, and workout quality, providing an indirect training pathway for lean-mass gain. The formula supplies almost no calories and lacks protein, creatine, or another direct mass-building ingredient.

Citrulline reaches a useful but not maximal amount, while betaine is far below a full performance dose. The named pump ingredients are mostly disclosed, but the mushroom-based performance blend hides its component details and prevents a complete potency assessment.

Glycerol, citrulline, arginine, and agmatine create a coherent stimulant-free pump formula that may support training volume. Avoiding caffeine reduces the chance that late use will disrupt sleep and recovery.

Citrulline is useful but below a stronger full-performance amount, while betaine is far below its typical ergogenic dose. The PeakO2 blend is not broken down into components, and no creatine or direct hypertrophy foundation is present.

B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

Pure L-Citrulline is named and its individual amount is disclosed. The 3,000 mg serving falls within the commonly used performance range. Citrulline-specific value is premium-priced despite a useful active amount.

A+ Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyD+ Value

Betaine anhydrous is explicitly named and its amount is fully disclosed. The 500 mg serving is well below a full performance dose, making it a minor part of this pump-focused formula. A low serving cost and several other performance ingredients help total-formula value, but betaine-specific dose efficiency remains limited.

A clearly identified hydrochloride form supplies a moderate amount in a workout powder. Immediate-release powder is easy to take in one serving but does not prolong delivery. High cost per gram makes the formula poor value for arginine alone.
