Analysis

LJ100 tongkat ali provides the clearest premium feature, while 120 mg of ginkgo and 1,500 mg of L-citrulline support blood-flow pathways. Fenugreek, ginseng, beet, and beta-sitosterol broaden the formula, but their amounts or marker details are not strong enough to anchor the product.

The ingredient mix is primarily aimed at libido and male performance rather than cognition, vision, or heart health. Ginkgo offers a narrow cognitive-circulation link, yet the absence of flavone and terpene standardization makes potency harder to assess.

MCT oil and BioPerine create an absorption-focused liquid-softgel format. Four softgels per serving and modest doses across several actives make the blend less compelling than a simpler, more targeted formula.

Who is it for
  • adults seeking a multi-pathway male-performance blend
  • people who prefer liquid softgels with botanical and circulation ingredients
Best for
  • libido and general male-performance support
  • secondary circulation support

Pros

  • Uses branded LJ100 tongkat ali
  • Provides a clinically plausible listed ginkgo amount
  • Discloses individual ingredient quantities
  • Includes MCT oil and BioPerine to support delivery

Cons

  • Fenugreek lacks active-marker standardization
  • Citrulline and beet are modest for stronger vascular support
  • Ginseng is included at a small amount
  • Four softgels create substantial pill burden

Warnings

  • Ginkgo may increase bleeding tendency with anticoagulants such as warfarin or antiplatelet medicines such as clopidogrel.
  • L-citrulline may add to nitrate or blood-pressure medicine effects and contribute to low blood pressure.
  • BioPerine may change the absorption of some medicines, making review important for drugs with a narrow therapeutic range.

Nutrient quality

69 High impact

L-citrulline and named extracts are recognizable, but ginkgo, fenugreek, and ginseng lack meaningful active-marker disclosure. Ginkgo has a useful listed amount, while L-citrulline is moderate and fenugreek, beet, and ginseng are modest for focused use.

Ingredient transparency

74 High impact

Every listed active is assigned a specific amount. The provided facts omit the complete excipient and softgel ingredient list.

Customer satisfaction

70 High impact

The supplied aggregate rating is strong. No specific review comments are supplied to identify repeated negative experiences.

Value for money

50 Moderate impact

Useful ginkgo and L-citrulline support some quality, but weak standardization and modest secondary doses limit what the formula delivers. The recurring cost is difficult to justify from the effective amounts of the main actives.

Ginkgo provides a direct cerebral blood-flow pathway for attention, while ginseng offers modest adaptogenic context. The formula is primarily intended for libido and vascular response rather than focused cognition.

Ginkgo reaches a useful amount but lacks marker and purity disclosure, while ginseng is underdosed. Ginkgo may increase bleeding risk for people using anticoagulant or antiplatelet medicines.

Citrulline · 1500 mg

Citrulline, beet powder, and ginkgo form a coherent nitric-oxide and circulation combination. Individual amounts are disclosed for each relevant active.

Citrulline and beet are below common targeted amounts, while beet nitrate yield and ginkgo markers are not stated. Ginkgo may increase bleeding tendency when combined with anticoagulant or antiplatelet medicines.

Ginkgo supplies situational brain-health relevance through cerebral circulation, but the formula is mainly designed for sexual performance. Other ingredients contribute little direct support for memory, focus, or long-term neuronal resilience.

The ginkgo amount is potentially useful, yet its active-marker standardization is not shown. Ginkgo may increase bleeding concern with anticoagulant or antiplatelet medicines.

Ginkgo provides a credible but narrow route to mental clarity through cognitive circulation. Its amount is useful, although extract standardization is not shown.

Ginseng is too small to add much adaptogenic depth, and no stimulant or meaningful precursor is present. The testosterone and circulation design makes productivity an incidental benefit.

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

Pure L-citrulline is listed at an amount suited to maintenance use but below the preferred performance range. The source and purity standards are not identified, and serving directions create a practical difference between daily maintenance and immediate-use portions. Cost efficiency is poor for a citrulline-focused purchase because much of the formula is devoted to oils and botanical ingredients.

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

The label names a ginkgo extract but does not disclose both key active-marker percentages or a recognized purity standard. The amount falls within the clinically used range and is listed separately rather than hidden in a blend. The cost per comparable clinical dose is very high, while uncertain standardization further weakens value.

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

A generic seed extract lacks a concentration ratio or active-marker standardization and is provided below the better-supported extract range. MCT oil, liquid softgels, and a meaningful black pepper extract provide strong absorption support, while the exact fenugreek amount remains clear. High serving cost weakens value because no premium branded fenugreek source is identified.
