Analysis

The powder provides 8 g of citrulline malate, 3.6 g of beta-alanine, and 2.5 g of betaine. Those amounts form a credible non-stimulant performance base, while 300 mg of branded Alpha-GPC adds a focus-oriented component.

The Alpha-GPC listing does not clarify active yield, and calcium form is unspecified. Sodium and potassium are present but magnesium is absent, so the product is not a complete hydration formula.

Stimulant-free use suits evening training or caffeine-sensitive athletes. Premium serving cost is easier to justify for the full pre-workout blend than for any single electrolyte or cognitive ingredient.

Who is it for
  • Caffeine-sensitive athletes
  • People training later in the day
  • Users seeking a fully dosed stimulant-free pre-workout
Best for
  • Workout performance
  • Muscular endurance
  • Stimulant-free focus support

Pros

  • Strong citrulline malate amount
  • Useful beta-alanine and betaine doses
  • Branded Alpha-GPC source

Cons

  • High serving cost
  • Alpha-GPC active yield is unclear
  • No magnesium electrolyte

Warnings

  • Beta-alanine commonly causes temporary skin tingling
  • Alpha-GPC may cause headache or nausea in sensitive users
  • People with kidney disease should review the potassium-containing formula with a clinician

Nutrient quality

93 Highest impact

Citrulline malate, branded beta-alanine, betaine, and alpha-GPC reach useful workout amounts. The stimulant-free formula is coherent and avoids obvious overdosing, though alpha-GPC remains moderate for a dedicated cognitive effect.

Ingredient transparency

85 Highest impact

Every active has a separate amount and no proprietary blend hides the formula. Flavor-system ingredients and complete mixing guidance are not supplied.

Customer satisfaction

67 High impact

The strong average rating has a small review base. No review excerpts describe taste, tolerance, ease of use, or repeated complaints, so those experiences remain uncertain.

Value for money

75 High impact

Strong doses and full transparency support premium quality, but the supply is short and each serving is expensive. The focused formula offers substance rather than label padding, yet ongoing value remains only moderate.

B Goal FitA Strength of SupportC CoverageB+ Formula Quality

Eight grams of citrulline malate and 270 mg potassium citrate provide strong, clearly disclosed support for exercise blood flow and vascular tone. The formula is focused on performance, so it does not cover lipid management, homocysteine, or cardiac energy.

Every active amount is visible, and the potassium form is favorable. Citrulline can add to the blood-pressure-lowering effects of nitrates or antihypertensive medicines, so susceptible users should discuss the combination with a clinician.

Alpha-GPC · 300 mg

Branded Alpha-GPC provides a direct acetylcholine precursor for focus and cognitive performance. The remaining formula supports exercise output rather than broader brain health.

The 300 mg source amount may yield only a lower-range active Alpha-GPC dose because active percentage is not stated. The stimulant-free design is coherent for training but lacks complementary memory, stress, or neuroprotection actives.

Alpha-GPC · 300 mg

Alpha-GPC provides some cognitive-aging relevance, while citrulline, beta-alanine, betaine, and electrolytes support physical capacity. The stimulant-free design avoids the sleep trade-off of the caffeinated version.

Most actives are performance ingredients rather than direct mitochondrial, glycation, NAD, collagen, or omega-3 support. Strong disclosure and practical athletic doses do not fully compensate for limited longevity-specific evidence.

Alpha-GPC · 300 mg

Branded Alpha-GPC provides a direct acetylcholine pathway in a stimulant-free performance formula. The listed amount does not clarify active yield, and the likely active contribution sits below a robust cognitive dose.

Citrulline, beta-alanine, betaine, and electrolytes may aid exercise but add little direct cognitive breadth. The formula therefore offers limited nootropic depth despite a relevant branded ingredient.

Alpha-GPC · 300 mg

Branded Alpha-GPC provides the only direct cognitive ingredient in an otherwise exercise-focused formula. Without caffeine, adaptogens, or a neurotransmitter precursor stack, productivity support is limited.

The listed Alpha-GPC amount may deliver only a modest active yield, and that yield is not clarified. Large exercise-performance doses dominate the formula and reduce its relevance to mental work.

Report overview
Potassium (Tripotassium Citrate Monohydrate) · 270 mg OverallScore71
A+ Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyF Value

Tripotassium citrate provides a well-absorbed and metabolically useful potassium source. The 270 mg serving is moderate but below the collection median. A high serving cost keeps potassium-specific value limited.

View ingredientView products
Sodium (Sodium Chloride, Sodium Citrate) · 110 mg OverallScore63
B Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyD+ Value

The combined sodium amount falls just below the preferred athletic range, although both sodium sources are clearly identified. Potassium citrate adds a well-absorbed supporting electrolyte, while magnesium and trace minerals are absent. The pre-workout ingredients also make the serving comparatively costly for sodium replenishment alone.

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

AlphaSize provides a recognized branded form, but the listed 300 mg does not clarify active yield. Assuming 50% yield, the estimated 150 mg active amount fits a lower maintenance range. The estimated cost per active dose is high despite the branded source.

Energy Powder Drink Mix Lemon Ginger

Lake Avenue Nutrition
B vitamins, electrolytes, and moderate caffeine support energy and focus more directly than most candidates in the supplied pool. It is not stimulant-free and lacks the original's citrulline, beta-alanine, betaine, and alpha-GPC dose depth.
69 Performance

Adrenal Cocktail + Wholefood Vitamin C

Jigsaw Health
Clearly identified natural salt, potassium, and whole-food vitamin C provide focused hydration support. The formula does not replace the original's pump or cognitive ingredients, but its electrolyte purpose is clearer than unrelated protein and joint candidates.
44 Performance

PectaSol-C Modified Citrus Pectin

ecoNugenics
Modified citrus pectin provides soluble fiber with some heart and cardiovascular alignment. It shares no meaningful pre-workout actives with the original, so it should be considered only when heart-focused fiber is the priority rather than exercise performance.
67 Budget

Adrenal Cocktail + Wholefood Vitamin C

Jigsaw Health
Meaningful sodium plus potassium and whole-food vitamin C support hydration at a much lower serving cost. It omits citrulline, beta-alanine, betaine, and alpha-GPC, so it is not a full stimulant-free pre-workout replacement.
48 Budget

Casein Protein Elite Series Triple Chocolate

Six Star Pro Nutrition
Casein protein and calcium cost less and may fit post-training protein intake. The formula lacks the original's pump, endurance, and focus ingredients, making it a nutrition alternative rather than a pre-workout.
49 Budget

HEXAPRO Chocolate

ALLMAX
Substantial blended protein with moderate calcium and potassium offers lower-cost workout nutrition. It does not provide citrulline, beta-alanine, betaine, or alpha-GPC, so performance support is far less direct.
72 Value

Hydrator Lemon Lime Flavored

Vega Sport
Clearly identified sodium chloride and potassium chloride provide straightforward hydration at low recurring cost. Electrolyte amounts are modest for heavy sweating and the formula omits every major pump, endurance, and focus active in the original.
65 Value

Adrenal Cocktail + Wholefood Vitamin C

Jigsaw Health
Sodium, potassium, and whole-food vitamin C provide economical hydration support. Missing salt-form detail and the absence of citrulline, beta-alanine, betaine, and alpha-GPC make it a partial substitute only.
37 Value

Glucosamine + Chondroitin + MSM

Jarrow Formulas
Glucosamine, chondroitin, manganese citrate, and vitamin C provide good joint-formula value. Sodium and potassium are incidental and the product does not address the original's pre-workout goals, so it is suitable only when joint support has replaced performance support as the priority.
