Testosterone Booster for Men (120 Caps)
Checked against public sources on August 7, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Listing brand: Revolution Science · package: REVSCI. Ownership and outside records for the listing brand may not describe the branding printed on the package. Confirm the package identity before treating them as the same brand.
“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.

The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed1
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently2
No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. NSF, IFOS, USP, and Informed-Sport were not checked in this record. This is a public-evidence limit, not a finding that testing did not occur.
“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
We looked and found no public proof. That does not count against the product.
What is worth knowing.

Evidence and sources
The exact product listing names “Revolution Science,” while the saved package/panel image reads “REVSCI.” This can reflect a product line, catalog error, changed listing, or different packaging; it does not prove substitution. …
Locked evidence record →Open the full source-linked findingCategory 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. …

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.
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 400 mg of ashwagandha per serving. Studies we found used 250 mg–600 mg a day, so this sits inside that range.
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 5 mg of boron per serving. Studies we found used 3 mg–10 mg a day, so this sits inside that range.
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 400 mg of tongkat ali (Eurycoma longifolia) per serving. Studies we found used 200 mg–400 mg a day, so this sits inside that range.
