What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.
What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.
What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.
Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.
The listing-image panel publishes 3 separately ingredients with amounts and 1 combined blend total. Ingredients inside a blend do not have separate amounts.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin B6 (as pyridoxine hydrochloride) | 2 mg | — | |
| Vitamin B12 (as methylcobalamin) | 50 mcg | — | |
| Zinc (as zinc chelate) | 1 mg | — | |
| Nugenix® Free Testosterone Complex: L-Citrulline Malate (2:1), Tesnor® [proprietary blend of Pomegranate Extract (peel) and Cocoa Extract (bean)], Tribulus Extract (fruit) | 1903 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a listed “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; the open question is whether those listed amounts are independently verified and how they compare with relevant research.
vision:claude-cli:subscription Amounts are shown as listed panel data, not independently lab-tested contents.
Every check we ran
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.
USPTO lists Direct Digital, LLC (LIMITED LIABILITY COMPANY) in DELAWARE, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.
Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
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.
Published sources describe how tribulus terrestris, zinc have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome. Sources: PubMed search: Tribulus terrestris testosterone trial.
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).
We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.
This means only that no enforcement record matched the brand name — it does not mean the product was tested, reviewed, or cleared by FDA. New and untested products also have no recall records.
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.
Exact-listing history records written-review counts from 39 on 2025-07-18 to 66 on 2026-07-21 (net +27). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
The package says distributed by: Adaptive Health, Charlotte, NC 28202. USPTO names Direct Digital, LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What to ask and check
Ask the brand or seller
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.
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.
What is the amount of each ingredient inside the proprietary blend?
A blend total tells you nothing about whether any single ingredient reaches a dose used in research. Brands may decline — that answer is informative too.
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
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.
Scan the barcode on the package and confirm it reads 678829000275.
A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.
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.
What the listing promises — claim by claim
| Claim | Status | What we found |
|---|---|---|
| Manufacturing claim “…MADE IN USA: Nugenix is made in the USA according to current Good Manufacturing Practices and using premium ingredients carefully sourced from the USA and around the glo” | Partly supported We looked for: the facility registration or certificate behind the claim | “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. |
| Origin claim “…MADE IN USA: Nugenix is made in the USA according to current Good Manufacturing Practices and using premium ingredients carefully sourced from the USA and around the glo” | Claimed, not verifiable We looked for: customs records or label filings showing where ingredients were sourced and where it was made | “Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product. |
| Benefit claim “…Feel stronger, Boost performance, and maintain that youthful edge…” | Partly supported We looked for: whether the ingredient doses on the label match the doses used in published research | Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed. |
“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.
This label vs. the doses studied
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Nugenix® Free Testosterone Complex: L-Citrul | shaded = doses used in studies (250 mg–1.5 g) · bar = this label | 1.903 g — above the studied range |
| Zinc (as zinc chelate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 1 mg — below the studied range |
Matching a studied dose does not mean the product works, and missing it does not mean it fails — it shows whether the label and the research are talking about the same amounts. Not a recommendation to take any amount.

Related research & consistency
tribulus terrestris — PubMed search: Tribulus terrestris testosterone trial · FDA — tainted sexual-enhancement products · ClinicalTrials.gov — 12 registered studies
ℹ Use pattern in research: human trials have generally not found testosterone increases in healthy men, despite frequent marketing to that effect.
zinc — NIH ODS — Zinc fact sheet · PubMed search: zinc supplementation trial · ClinicalTrials.gov — 1,598 registered studies
ℹ Use pattern in research: daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice.
