Trouble on record?Recall check not run yeta gap in our records, not a finding about the product
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Category context: sexual-enhancement products carry documented FDA risk
This is category history, not proof about this product, but it changes how much unsupported claims deserve to be trusted.
Evidence and sources
FDA's health-fraud program documents sexual-enhancement products as the most common supplement category found to contain undeclared prescription-drug ingredients. This is a category-level documented fact from FDA's public database — not a test result for this specific product. …

Every ingredient shows its amount · 10 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 675 mg of ashwagandha per serving. Studies we found used 250 mg–600 mg a day, so this sits above that range.
0studied 250 mg–600 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 15 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
0studied 8 mg–40 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
