How to read this report
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.
What the label discloses
The listing-image panel publishes an amount for each of its 9 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin D (as Cholecalciferol) | 100 mcg (4,000 IU) | — | |
| Vitamin K (as Phytonadione) | 100 mcg | — | |
| Zinc (as Zinc Citrate) | 30 mg | — | |
| Tongkat Ali (Eurycoma longifolia Root Extract) | 1,000 mg | — | |
| Fenugreek (Trigonella Foenum-Graecum) Seed Extract | 1,000 mg | — | |
| L-Taurine | 675 mg | — | |
| Shilajit (Asphaltum s. Mineral Extract) | 400 mg | — | |
| Boron (as Boron Citrate) | 4 mg | — | |
| Vitamin K2 (as Menaquinone-7 Dicalcium Phosphate) | 100 mcg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “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 declared amounts are independently verified and how they compare with relevant research.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
No data yet: Multiple USPTO brand-owner records are shown
USPTO returned multiple live supplement-class records for the exact brand wordmark: Xufeng Liu, Mars Health, Inc.. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
No data yet: Testing claimed — documentation not found
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
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.
Category context: sexual-enhancement products carry documented FDA 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).
Research context is available for the listed ingredients
Published sources describe how boron, tongkat ali, fenugreek, zinc 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.
Not found in NIH's DSLD label registry
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, not a strike.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
180-day review-count history is on file
Exact-listing history records written-review counts from 0 on 2026-04-28 to 19 on 2026-07-20 (net +19). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…PORT MOOD SUPPORT ENERGY SUPPORT Made in USA Third Party Tested Non-GMO This is the ONLY official Mars Men p…” | Claimed, not verifiable We looked for: a named laboratory, a certificate of analysis, or a certification-registry entry | No named laboratory, no certificate of analysis, and no certification-registry entry matching this product was located. |
| Speed-of-results claim “…oduct to take full effect. If you do not see results in 90 days, contact us for a refund on your first purch…” | No evidence located We looked for: a study measuring the stated outcome over the stated time | No study measuring the stated outcome over the stated timeframe was located for this product. |
| Origin claim “…STRENGTH SUPPORT MOOD SUPPORT ENERGY SUPPORT Made in USA Third Party Tested Non-GMO This is the ONLY…” | 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 “…gkat Ali, Fenugreek, Shilajit & Boron - Male Support - Libido, Energy & Muscle Growth Support - 3…” | 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 — see Related research below. 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
Why is this shown?
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Boron (as Boron Citrate) | shaded = doses used in studies (3 mg–10 mg) · bar = this label | 4 mg — within the studied range |
| Tongkat Ali (Eurycoma longifolia Root Extrac | shaded = doses used in studies (200 mg–400 mg) · bar = this label | 1 g — above the studied range |
| Fenugreek (Trigonella Foenum-Graecum) Seed E | shaded = doses used in studies (500 mg–600 mg) · bar = this label | 1 g — above the studied range |
| Zinc (as Zinc Citrate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 30 mg — within 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.
Documented cautions
- fenugreek — studied as a standardized extract over 8–12 weeks; may interact with blood-thinning and blood-sugar medication — documented interaction, not advice
- zinc — daily oral use; sustained high intakes can interfere with copper absorption — a documented interaction, not advice
Statements from published sources about these ingredients — not advice about this product, and not a complete safety review. Anyone taking medication should talk to a pharmacist or clinician.
Verifiability profile — 2 of 6 public signals
What this listing gives the public to check. Publishing these signals doesn't prove quality — but withholding them means claims can only be taken on faith.
