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 an amount for each of its 9 listed rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Magnesium (as Magnesium Oxide) | 200 mg | — | |
| Zinc (as Zinc Oxide) | 30 mg | — | |
| Tribulus Terrestris (fruit) | 750 mg | — | |
| Chrysin (Oroxylum indicum) (seed) | 75 mg | — | |
| Horny Goat Weed (Epimedium sagittatum) (aerial) | 50 mg | — | |
| Longjack/Tongkat Ali (Eurycoma longifolia) (root) | 50 mg | — | |
| Saw Palmetto Berries (Serenoa repens) (berry) | 50 mg | — | |
| Hawthorn Berries (Crataegus pinnatifida Bunge) (berry) | 50 mg | — | |
| Cissus Quadrangularis (stem) | 50 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:google/gemini-2.5-flash 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 Research Labs LLC (LIMITED LIABILITY COMPANY) in UTAH, 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.
UPCitemdb resolves 663387832871 to "Pharmacist Recommended 2 for 1 Promo(180ct) Testosterone Booster Enhancement by " (Research Labs) — consistent with this listing.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Documented concerns
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
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
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 magnesium, tongkat ali, tribulus terrestris, horny goat weed 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 — Magnesium fact sheet, PubMed search: magnesium glycinate supplementation.
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).
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. (475 mL) PREMIER RESEARCH LABS UPC Code: 80773500137 packaged in plastic HDPW bottles”. FDA recorded the reason as “Product spoiling over time; spoilage visible beneath lid/closure upon opening”. Verify at FDA’s recall database.
The package says distributed by: Research Labs, 138 E. 12300 S. Ste C-443 | Draper, UT 84020. USPTO names Research Labs LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.
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.
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.
Were the endorsing professionals compensated, and what exactly did they review?
An endorsement can be genuine and still not mean the product was tested. Ask whether they reviewed the formula, the manufacturing, or only the marketing.
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 663387832871.
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 |
|---|---|---|
| Professional-endorsement claim “…Pharmacist Recommended and #1 Recommended Test Booster Supplement by Men over 30*, Satisfaction Guaranteed Clinically researched natural ingredients that help to increas” | Marketing credential We looked for: who the professionals are, whether they were compensated, and what the endorsement covers | A professional endorsement is a marketing credential, not clinical evidence. Public sources don’t establish who was consulted, whether they were paid, or what specifically they reviewed. |
| Manufacturing claim “…Made in the USA in a certified and GMP approved facility with powerful all natural ingredients: Magnesium, Zinc, Tribulus Terrestris, Chrysin, Horny Goat Weed, Longjack ” | 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 the USA in a certified and GMP approved facility with powerful all natural ingredients: Magnesium, Zinc, Tribulus Terrestris, Chrysin, Horny Goat Weed, Longjack ” | 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 “…Increase Lean Muscle Energy Strength.…” | 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 |
|---|---|---|
| Magnesium (as Magnesium Oxide) | shaded = doses used in studies (200 mg–420 mg) · bar = this label | 200 mg — within the studied range |
| Longjack/Tongkat Ali (Eurycoma longifolia) ( | shaded = doses used in studies (200 mg–400 mg) · bar = this label | 50 mg — below the studied range |
| Tribulus Terrestris (fruit) | shaded = doses used in studies (250 mg–1.5 g) · bar = this label | 750 mg — within the studied range |
| Horny Goat Weed (Epimedium sagittatum) (aeri | shaded = doses used in studies (500 mg–1 g) · bar = this label | 50 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
magnesium — NIH ODS — Magnesium fact sheet · PubMed search: magnesium glycinate supplementation · WebMD: magnesium · FDA — tainted sexual-enhancement products · ClinicalTrials.gov — 3,206 registered studies
ℹ Use pattern in research: daily oral use; chelated forms (glycinate) are studied for absorption — note labels may state compound mass rather than elemental magnesium, which differs ~7-fold.
tongkat ali (Eurycoma longifolia) — PubMed search: Eurycoma longifolia randomized trial · NIH NCCIH — Herbs at a glance · ClinicalTrials.gov — 1 registered studies
ℹ Use pattern in research: extract standardization varies widely between products; a raw-powder milligram figure is not comparable to a standardized-extract dose used in studies.
tribulus terrestris — PubMed search: Tribulus terrestris testosterone trial · 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.
horny goat weed (Epimedium) — PubMed search: Epimedium icariin clinical · FDA — tainted sexual-enhancement products · ClinicalTrials.gov — 3 registered studies
ℹ Use pattern in research: mostly preclinical (cell and animal) evidence; human trials are limited. This is also FDA’s most-cited category for undeclared prescription drugs.
