Does the marketing hold up?

Couldn’t verify means public proof was not found; it is not a mark against the product. Ingredient research is not treated as a trial of this exact product.

Partly confirmed1

Advertised health or performance benefit

Published research exists for ingredients in this formula — see Related research below. Whether this product’s doses match those studies could not be confirmed.

Evidence →

Claimed without support found1

“Clinically tested” or “science-backed”

No named, citable study of this product or formula was located in public sources. The claim may rest on ingredient-level research rather than a trial of this product.

Evidence →

?Couldn’t verify independently3

GMP or manufacturing-quality language

Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located.

Evidence →
US manufacturing or origin language

“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.

Evidence →
1 more public-evidence limit
“Third-party tested”

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.

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…

Locked evidence record →Open the full source-linked finding
Checks outIs the label honest?

Every declared ingredient has an amount · 8 quantified rows.

You can compare each declared dose with research instead of guessing what is hidden inside a 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.

Confirmed evidence

What checked out01

These checks found support in the public record. They confirm specific facts, not the product as a whole.

Every ingredient amount is disclosed

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Confirmed

Documented concerns

What needs caution00

These are documented contradictions or claims that need more evidence. They are separate from missing data.

No contradictions or product-specific cautions were found at this check depth.

Unresolved public record

What is still missing06

We looked for these signals but could not settle them from public sources. A gap is not a strike.

“Lab tested” claimed, but no lab or report named

The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is retained, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.

No data

Multi-ingredient formula — panel read, serving weight unknown

We read the full Supplement Facts panel from the listing-image panel (below), but the label doesn’t state a serving weight, so the arithmetic can’t run. A gap in the label’s information, not evidence of a problem.

No data

Research context is available for the listed ingredients

Published sources describe how boron, tongkat ali, fenugreek, tribulus terrestris have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: NIH ODS — Boron fact sheet, PubMed search: boron supplementation testosterone.

No data

This category has documented FDA fraud risk

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. Source: fda.gov (linked in Related research).

No data

This item belongs to a catalog variation family

The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.

No data

180-day review-count history is on file

Exact-listing history records written-review counts from 131 on 2026-02-21 to 120 on 2026-07-21 (net -11). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

No data

What to ask and check

What would settle the open questions

Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.

Ask the brand or seller

1

Can you send the certificate of analysis (COA) for the lot number on my bottle?

A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.

2

Which specific study supports this claim — and was it run on this exact formula?

Ask for the citation, how many people took part, the dose used, and whether the study tested this product or just one ingredient in it. Ingredient research is not product evidence.

3

What is the product’s UPC or GTIN?

The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.

4

Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?

Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.

5

Where are the ingredients sourced, and where is the product manufactured?

“Made in USA” can describe only the final bottling step. Ask which country the actives came from and whether the facility is audited.

Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.

Check for yourself — no one’s permission needed

1

Compare the panel on the bottle in your hand to the one shown in this record.

Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.

2

Check the lot number and expiry on the bottle against any COA you’re given.

A certificate that doesn’t name your lot doesn’t describe what you’re holding.

These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.
