Nootropics Depot Tribulus Extract Capsules | 500mg | 20% Protodioscin…

Our verdict

Nootropics Depot Tribulus Extract Capsules | 500mg | 20% Protodioscin… works out to $0.47 per serving of tribulus terrestris, at 500mg per serving in capsule form. That puts it above the median of the 16 tribulus terrestris products we can price per dose, where the typical serving costs $0.15, a Value Index of 0.3 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $14.00 a month. We could not verify a third-party certification for Nootropics Depot in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
