Checked against public sources on August 16, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Ingredient amounts are hidden inside “Natural Booster Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.
“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.

We read 10 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
The public sources did not settle the marketing promises on this label.
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.
We looked and found no public proof. That does not count against the product.

Headlines first. Open evidence only when you want the source trail.
This is category history, not proof about this product, but it changes how much unsupported claims deserve to be trusted.
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. …

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.
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 10 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 100 mg of tongkat ali (Eurycoma longifolia) per serving. Studies we found used 200 mg–400 mg a day, so this sits below that range.
