Systematic review and meta-analysis, 2024Tongkat Ali Extract is the lead active here, studied most for testosterone already in the normal range. 8 human studies on Tongkat Ali Extract back this formula, each one cited. Each serving carries 100 mg of Tongkat Ali Extract, inside the range the published research used. Who it fits: skews toward men, adults.
Verified by IngredientMDThe panel on the left is the one we evaluated, line by line.
All 1 actives checked against the clinical evidence: dose, form, and what the research actually shows.
Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Strong evidence, strong dose".
The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.
Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.
Public health figures the engine matched to this formula's ingredients. Reported by their source, cited and dated, never written by the brand.
