Evidence →“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

Does the marketing hold up?
The observed listing says it is tested, but names no lab or certifier. A testing badge without an issuer or report is a marketing claim, not evidence. Ask for the lab name and lot-specific report.

Evidence and sources

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. So…

Every ingredient shows its amount · 3 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.

Dose and research context
The label amount is shown beside the ranges used in the linked ingredient studies.
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 500 mg of tongkat ali (Eurycoma longifolia) per serving. Studies we found used 200 mg–400 mg a day, so this sits above that range.
0studied 200 mg–400 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
