Product score

60 / 100Good
Category average
66.6 / 100

This is a multi-ingredient nighttime testosterone-support product, but the proprietary blend prevents judging the individual botanical doses; the label also gives no directions in the supplied information.

Score before rubric limits: 64.6 / 100.

Scoring criteria
  • Quantity

    75 / 100

    The 932 mg proprietary blend combines multiple ingredients without disclosing their individual amounts, leaving the principal botanical dose and its adequacy unresolved.

  • Form

    75 / 100

    The listed botanical extracts and powders have no established overall absorption or tolerability advantage as this blend, and no special delivery system is identified.

  • Convenience

    85 / 100

    Directions are not supplied, so I assume one labelled serving of two caplets once daily; 30 servings provide 60 caplets.

  • Label accuracy

    100 / 100

    The supplied panel reports a total proprietary-blend amount and gives no contradictory amount or unsupported label claim.

  • Matches the studied extract

    75 / 100

    The species and plant parts are partly identified, but standardization and complete preparation details are unavailable to assess match with relevant human research.

  • Purity

    75 / 100

    No product-specific purity testing or contaminant information is supplied, so purity remains unresolved.

  • Cofactors

    0 / 100

    The quantified magnesium, L-theanine, and melatonin are not established as complementary cofactors for the stated testosterone-support role.
