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.
The 10 mg biotin claim matches the panel
We did the comparison: the listing claims 10 mg of biotin, and the listing-image panel shows 10 mg biotin 2 capsules. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Vitamin A (as Retinyl Palmitate) | 2,700 mcg | — | |
| Vitamin C (Ascorbic Acid) | 100 mg | — | |
| Vitamin D3 (Cholecalciferol) | 2.5 mcg | — | |
| Vitamin E (as D-alpha Tocopheryl Succinate) | 10 mg | — | |
| Thiamin (as Thiamin HCI) | 5 mg | — | |
| Riboflavin | 5 mg | — | |
| Niacin (as Niacinamide) | 5 mg | — | |
| Vitamin B6 (as Pyridoxine HCI) | 5 mg | — | |
| Folate (as 334mcg Folic Acid) | 568 mcg DFE | — | |

| Ultimate Hair + Beard Proprietary Complex | 300 mg | — |
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; any remaining comparison concerns the front-label framing.
vision:google/gemini-flash-1.5 Amounts are shown as declared panel data, not independently lab-tested contents.
Every check we ran
Ingredient amounts are hidden inside a blend
The panel lists “Ultimate Hair + Beard Proprietary Complex” as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.
No data yet: Testing claimed — documentation not found
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 yet: Review-count history: not available
Marketplace rating not shown★ — rating count unavailable. No exact-listing count history was available, so no review-pattern claim is made.
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.
Research context is available for the listed ingredients
Published sources describe how collagen peptides, 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: collagen peptide supplementation trial, WebMD search: collagen.
Public label filing not retained
This record does not currently hold an identity-bound public label filing for the exact product. That is a LookCloser coverage gap, not evidence that no filing exists.
Brand ownership record not retained
This record does not hold an exact, supplement-class public ownership record for the brand. That is a LookCloser coverage gap, not evidence that the brand has no owner or that the product is improper.
UPC valid, no independent record
Check digit passes; no third-party database record found yet. Coverage gaps are common — not a strike.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Clinical-evidence claim “…r Loss* FOR MAXIMUM RESULTS. FORMULATED WITH CLINICALLY PROVEN PATENTED INGREDIENTS WORLD'S PUREST MSM POWD…” | No evidence located We looked for: a named, citable clinical study of this product or formula | 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. |
| Quality-testing claim “…NON GMO INGREDIENTS 3RD PARTY CERTIFIED FOR PURITY & POTENCY LAB TESTED MADE IN USA WITH GLOBALLY SOURCED…” | Claimed, not verifiable We looked for: the observed listing, retained brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried | 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. |
| Manufacturing claim “…TED MADE IN USA WITH GLOBALLY SOURCED INGRED GMP FACILITY Non-GMO MADE WITH NON” | Claimed, not verifiable We looked for: the facility registration or certificate behind the claim | Facility-level claims can be accurate and still say nothing about this product’s contents. No registration document was located. |
| Origin claim “…TY CERTIFIED FOR PURITY & POTENCY LAB TESTED MADE IN USA WITH GLOBALLY SOURCED INGRED GMP FACILITY No…” | 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 “…everything you need for fast hair regrowth. Supports Hair Regrowth* Thicker & Manlier Beard* Figh…” | 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 |
|---|---|---|
| Hydrolyzed Bovine Collagen | shaded = doses used in studies (2.5 g–15 g) · bar = this label | 200 mg — below the studied range |
| Zinc (as Zinc Citrate) | shaded = doses used in studies (8 mg–40 mg) · bar = this label | 15 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
- 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.
