Analysis

Ginkgo extract at 120 mg and L-citrulline at 1,500 mg provide the clearest support for circulation and related cognitive function. Standardized tongkat ali and ginseng add a performance focus, while the fenugreek extract lacks an active-marker specification.

The formula is more coherent for general male performance than for brain, vision, or cardiovascular support. Beet powder, beta-sitosterol, and several botanicals are present at modest amounts, so the long ingredient list should not be mistaken for deep coverage of every listed goal.

Four softgels and a large MCT oil amount create a substantial serving. Ginkgo standardization and purity details are missing, and the product is a weak fit for anyone mainly seeking a dedicated ginkgo or citrulline supplement.

Who is it for
  • adults seeking a broad male-performance formula with secondary circulation support
  • people who prefer oil-based softgels and can manage a four-softgel serving
Best for
  • combined libido and general performance support
  • incidental ginkgo-based circulation support

Pros

  • Provides 120 mg of ginkgo extract
  • Uses standardized tongkat ali markers
  • Lists each major ingredient amount separately
  • Includes MCT oil and BioPerine for an absorption-focused format

Cons

  • Citrulline is modest for stronger performance use
  • Fenugreek and ginkgo active-marker standardization is not disclosed
  • Many ingredients target different goals without strong depth
  • Four softgels create a high daily pill burden

Warnings

  • Ginkgo may increase bleeding tendency with anticoagulants such as warfarin or antiplatelet medicines such as clopidogrel.
  • L-citrulline may add to the blood-pressure-lowering effects of nitrates or antihypertensive medicines.
  • Cayenne and BioPerine may aggravate digestive irritation in sensitive users.

Nutrient quality

70 High impact

L-citrulline and named botanical extracts are recognizable forms, but most extracts lack active-marker standardization. Ginkgo has a useful amount, while L-citrulline is moderate and fenugreek, beet, and ginseng are modest for targeted use.

Ingredient transparency

75 High impact

Every listed active has a specific amount. The provided label facts do not include a complete excipient or softgel ingredient list.

Customer satisfaction

71 High impact

The supplied aggregate rating is strong. No specific review comments are provided to assess whether negative complaints repeat.

Value for money

43 Lower impact

Useful ginkgo and L-citrulline are offset by weak standardization and several modest supporting amounts. The serving provides limited active value relative to its recurring cost.

Ginkgo and related cognitive botanicals may support circulation, memory, and mental performance. Standardized extracts and meaningful doses strengthen the case when they are clearly disclosed.

Benefits remain more modest and variable than the label may imply. Proprietary blends or ingredients aimed at non-cognitive goals reduce transparency and focus.

Citrulline · 1500 mg

L-citrulline, beet, ginkgo, and ginseng touch nitric oxide and circulation pathways. The testosterone-focused stack includes many botanicals that are not established heart-support actives.

Citrulline is present below common higher vascular amounts, while beet and several botanicals are modest. Ginkgo may increase bleeding tendency with anticoagulant or antiplatelet medicines.

The disclosed ginkgo amount may support circulation-related cognitive function, and ginseng may add some fatigue resistance. Most of the formula targets vascular or testosterone-related performance rather than attention, mental clarity, or sustained work output.

Ginkgo reaches a typical amount, but no flavone-glycoside or terpene-lactone standardization is provided. Ginkgo may increase bleeding risk when combined with anticoagulants such as warfarin or antiplatelet medicines such as clopidogrel.

The 120 mg ginkgo extract is the clearest cognitive ingredient and may support cerebral circulation. Most of the formula is designed for testosterone and exercise support rather than memory, focus, or long-term brain resilience.

The ginkgo amount is disclosed, but no flavonoid or terpene standardization is provided. Ginkgo may increase bleeding tendency when combined with anticoagulant or antiplatelet medicines.

Report overview
Citrulline · 1500 mg OverallScore62
B- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

Pure L-citrulline is clearly listed at a solid maintenance dose, but it remains modest for peak exercise performance. The complex softgel formula does not disclose citrulline sourcing, purity testing, or a recognized ingredient standard. Four softgels create a sizable serving, and the cost per gram of citrulline is poor.

Ginkgo · 120 mg OverallScore48
F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

The disclosed ginkgo amount reaches the usual clinical range, but the label provides no active-marker percentages or purity standard. The formula's other ingredients mainly target a different use, so they do little to strengthen its value as a ginkgo supplement. Ginkgo may increase bleeding risk with anticoagulant or antiplatelet medicines, and the large softgel serving adds pill burden.

Fenugreek · 200 mg OverallScore45
D- Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

The formula uses a generic fenugreek extract without disclosed saponin standardization. BioPerine and a liquid softgel with medium-chain triglyceride oil provide strong absorption support, but the fenugreek amount remains below preferred standardized-extract dosing. The high serving cost limits value, and ginkgo may raise bleeding risk for people using anticoagulant or antiplatelet medicines.
