Analysis

Tongkat ali provides the clearest testosterone-oriented rationale, while maca and two ginseng species support energy, stress response, and sexual well-being. Epimedium, tribulus, and muira puama add overlapping libido-focused pathways.

Ingredient weights are listed individually, but marker percentages are incomplete for tongkat ali, icariin, and tribulus saponins. Ginseng and muira puama are modest additions, so the long label offers more breadth than depth.

The larger bottle supports a longer routine. Serving value is practical for a seven-botanical formula. It best fits adults seeking broad male-vitality support rather than a precise foundational hormone formula.

Who is it for
  • Adults seeking broad male-vitality support
  • Users comfortable with a seven-botanical formula
  • People who tolerate stimulating herbs
Best for
  • Libido-oriented support
  • Daytime vitality
  • Users wanting tongkat ali with maca and ginseng

Pros

  • Plausible tongkat ali amount
  • Seven botanical weights are disclosed
  • Maca and ginseng broaden vitality support

Cons

  • Key active-marker percentages are incomplete
  • Several companion botanicals are lightly dosed
  • No zinc, vitamin D, or magnesium

Warnings

  • Ginseng and epimedium may cause insomnia, palpitations, or blood-pressure changes in sensitive users.
  • Tongkat ali and the broader blend affect hormone-related pathways and need extra care with hormone-sensitive conditions or treatment.
  • Tribulus and ginseng may affect blood pressure or glucose control, so relevant medicines require compatibility review.

Nutrient quality

70 High impact

The broad stack contains useful tongkat ali and maca amounts but limited standardization. Several smaller ingredients dilute depth and lean more toward libido than direct hormone support.

.

Ingredient transparency

82 Highest impact

Individual botanical amounts are fully visible without a hidden blend. Complete directions, inactive ingredients, and most extract standards remain missing.

.

Customer satisfaction

69 High impact

The supplied average is strong and backed by very large volume. No review themes were provided, so consistency and purpose-specific experience cannot be assessed.

.

Value for money

66 High impact

The broad active list and reasonable serving cost provide fair value. Missing extract standards and several small doses keep the formula from comparing more strongly.

C+ Goal FitC- Strength of SupportC CoverageB- Formula Quality

Tongkat ali offers the clearest testosterone-related active, while tribulus, maca, epimedium, and ginseng lean more toward libido and vitality. Several pathways are represented, but direct hormone evidence is mixed and botanical standardization is mostly absent.

Individual ingredient amounts are disclosed, yet the broad formula spreads the serving across seven botanicals. Tongkat ali is plausibly dosed, while the smaller ginseng and muira puama amounts and unstandardized tribulus limit confidence in consistent effects.

Tribulus · 250 mg OverallScore57
D- Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyC Value

The extract lacks a disclosed saponin percentage and plant-part source, leaving active quality uncertain. Its 250 mg amount reaches the entry-level potency range, and the exact amount is clearly listed. Cost efficiency is moderate because the active strength cannot be verified.
