Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.

Trouble on record?Brand history — not this 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.

◐Partly confirmed2
“in the USA in a certified and GMP approved facility with powerful all natural ingredients: Magnesium, Zinc, Tribulus Terrestris, Chrysin, Horny…”
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.

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
This recall is not about the product on this page. Premier Research Labs LLC recalled a different product on June 15, 2022. FDA has since closed that case. The recalled item was “AloePro Dietary Supplement Made With Organic ALOE VERA LIQUID 16 FL Oz.…”

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 · 9 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 200 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside that range.
