  • Includes BioPerine for absorption

Nutrient quality

78 High impact

The combination of botanicals and amino acids addresses multiple pathways for systemic vitality. However, the 60 mg dose of L-Tyrosine is extremely low and unlikely to provide significant cognitive support independently.

Ingredient transparency

92 Highest impact

Labeling discloses the amounts for most active components, though some are listed within a complex blend. Transparency is good, allowing for a reasonable assessment of formula strength.

Customer satisfaction

87 Highest impact

Ratings are generally positive, suggesting the product meets expectations for its intended use. Feedback indicates that the formula is well-regarded for its role in maintaining overall physical drive.

Value for money

71 High impact

The cost per serving is high compared to simpler formulas, reflecting the diverse range of ingredients. Value is primarily found in the multi-component synergy rather than the dose of any single nutrient.

This performance formula uses ashwagandha root powder to help balance the body during physical stress. While it includes an absorption-enhancing complex, the dose of ashwagandha itself is relatively low for an unextracted root powder.

This complex libido-focused supplement contains only a trace amount of L-Tyrosine, making it ineffective for targeted dopamine support. While the label is clear, the price per gram of tyrosine is extremely high.
