“School Labs Pride - All our products are formulated in Southern California and made in the USA with the highest GMP standards, certified by…”
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.
Ingredient research can support context, but it is not a trial of this exact product.

?Couldn’t verify independently2
“School Labs Pride - All our products are formulated in Southern California and made in the USA with the highest GMP standards, certified by…”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
“TESTED”
Evidence →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.
Needs explanationAny trouble in public records?
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 · 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.

Reviews rose from 158 to 253 between August 12, 2025 and August 25, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 158 to 253 between August 12, 2025 and August 25, 2026. The largest rise inside any single 30-day window was about 18, so the count moved in steps rather than in one burst.

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 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.
