Ingredient amounts are hidden inside “DHT Blocker & Hair Growth
The panel lists “DHT Blocker & Hair Growth Blend” (1060 mg) as a combined amount. A blend total can’t tell you whether any single ingredient reaches a dose used in research.

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.
Panel, decoded
The 1.5 g number matches named panel rows
MARKETING1.5 g — per-serving claim
PANELDHT Blocker & Hair Growth Blend 1.06 g + Men's Vitality and Healthy Aging Blend 420 mg = 1.48 gDHT Blocker & Hair Growth Blend 1.06 g + Men's Vitality and Healthy Aging Blend 420 mg
component totalWe did the comparison: the per-serving claim uses 1.5 g, which equals DHT Blocker & Hair Growth Blend 1.06 g + Men's Vitality and Healthy Aging Blend 420 mg. It is a combined amount, not the amount of one ingredient. This explains the label framing; it does not independently test the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Biotin | 5000 mcg | — | |
| Vitamin D (as Cholecalciferol) | 20 mcg | — | |
| Zinc (as Zinc Gluconate) | 15 mg | — | |
| DHT Blocker & Hair Growth Blend | 1060 mg | — | |
| Men's Vitality and Healthy Aging Blend | 420 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; any remaining comparison concerns the front-label framing.

Every check we ran
Confirmed evidence
What checked out0
These checks found support in the public record. They confirm specific facts, not the product as a whole.
Nothing could be independently confirmed from the available record.
Documented concerns
What needs caution2
These are documented contradictions or claims that need more evidence. They are separate from missing data.
Headline number is a blend total, not one named ingredient
The listing uses 1.5 g for biotin. The panel lists biotin at 0.005 g; the other 1,495 mg is the rest of the listed blend. Panel addition: DHT Blocker & Hair Growth Blend 1060 mg + Men's Vitality and Healthy Aging Blend 420 mg = 1,480 mg. This documents the framing; it does not establish what is inside the product.
Unresolved public record
What is still missing9
We looked for these signals but could not settle them from public sources. A gap is not a strike.
Listing and photo-read panel need confirmation
The listing says 1.5 g, while our photo read produced Biotin at 5 mg per serving. OCR can confuse small units and digits, so this remains unresolved until checked against the physical label.
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.
“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 saved, so the claim cannot be verified as stated. NSF, IFOS, USP, and Informed-Sport were not checked in this record.
Cost to reach a studied dose
At 1.0 serving(s) a day to reach the low end of the studied range (8–40 mg), this product runs roughly $30 per month. A price observation, not a recommendation.
Research context is available for the listed ingredients
Published sources describe how 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 — Zinc fact sheet, PubMed search: zinc supplementation trial.
Public label filing not saved
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.
No recall found — which is not the same as being tested
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.
Brand ownership record not saved
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 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
Answered by the panel: the 1.5 g listing number equals DHT Blocker & Hair Growth Blend 1.06 g + Men's Vitality and Healthy Aging Blend 420 mg. What lot-specific document confirms those listed amounts?
The panel resolves what the headline number includes. The remaining question is whether the product in hand matches those listed amounts; ask for a lot-specific certificate of analysis.
2
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.
3
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.
4
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.
5
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
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
Scan the barcode on the package and confirm it reads 198715127188.
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.
3
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
Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
| Claim | Status | What we found |
|---|---|---|
| Quality-testing claim “…Each batch is independently lab tested for potency and purity, with results published online for full transparency.…” | Claimed, not verifiable We looked for: the observed listing, saved 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. A related brand page names no testing issuer and links no product-bound report; its UPC is not published. 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 “…USA QUALITY & TRANSPARENCY: Made in the USA in a GMP-certified facility.…” | 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…” | 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 “…NATURAL DHT BLOCKER FOR HAIR GROWTH: Formulated to support healthy DHT levels — a key driver of hair thinning.…” | 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
Why is this shown?
An ingredient can be well-studied at one amount and barely studied at the amount in your bottle. This lines the label up against the doses researchers actually used. It answers ‘are these the same numbers?’ — never ‘should you take this?’
| Ingredient | Where this label sits | Reading |
|---|---|---|
| Zinc (as Zinc Gluconate) | 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
