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 12 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calories | 20 | — | |
| Total Carbohydrate | 5g | — | |
| Total Sugars | 3g | — | |
| Includes Added Sugars | 3g | — | |
| Vitamin D (as Cholecalciferol) | 84mcg | — | |
| Sodium (as Sodium Citrate) | 15 mg | — | |
| Boron Amino Acid Chelate (yielding 10 mg of Boron) | 200 mg | — | |
| Horny Goat Weed (Epimedium Sagittatum) Extract | 100 mcg | — | |
| Fenugreek (Trigonella foenum-graecum) Extract (seed) | 100 mcg | — | |
| Black Maca (Lepidium Meyenii) Extract (root) | 100 mcg | — | |
| Tongkat Ali Longjack (Eurycoma Longifolia) Extract (root) | 100 mcg | — | |
| Tribulus Terrestris Extract (fruit) | 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
Panel carries documented template or translation artifacts
The panel carries these quoted observations: “Calories has no unit”. US-market labels are produced under cGMP controls; these are template or translation artifacts worth checking, not proof that the label is fabricated or that the product is unsafe.
Exact trademark owner identified
USPTO lists Stefanov, Vadim (INDIVIDUAL) in ISRAEL 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.
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 4.2★ across 1,938 ratings. 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.
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, maca root 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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Extraordinary physical claim “…Booster Gummies, Male Enhancing Supplement, Add 2 in” Enlargement Gummies for Men , Male Enhancem…” | No evidence located We looked for: a published human trial of this product showing the stated physical change | No published trial of this product supporting the stated physical change was located. Extraordinary claims need evidence proportionate to them; none is on the public record. |
| Quality-testing claim “…y, Wheat, or Soy NO Artificial Sugar or Salt LAB TESTED PURITY & POTENCY” | 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. |
| Benefit claim “…cked with natural, powerful ingredients that enhance blood flow, ensuring stronger and longer-las…” | 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 Amino Acid Chelate (yielding 10 mg of | shaded = doses used in studies (3 mg–10 mg) · bar = this label | 10 mg — within the studied range elemental amount, as the label states it yields |
| Tongkat Ali Longjack (Eurycoma Longifolia) E | The photo-read amount (0.1 mg) is implausibly small for an extract and is likely an mg/mcg reading error, so we withhold the comparison. Studies typically use 200 mg–400 mg. | |
| Fenugreek (Trigonella foenum-graecum) Extrac | The photo-read amount (0.1 mg) is implausibly small for an extract and is likely an mg/mcg reading error, so we withhold the comparison. Studies typically use 500 mg–600 mg. | |
| Black Maca (Lepidium Meyenii) Extract (root) | The photo-read amount (0.1 mg) is implausibly small for an extract and is likely an mg/mcg reading error, so we withhold the comparison. Studies typically use 1.5 g–3 g. | |
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
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 — 1 of 6 public signals

Related research & consistency
boron — NIH ODS — Boron fact sheet · PubMed search: boron supplementation testosterone · FDA — tainted sexual-enhancement products · ClinicalTrials.gov — 989 registered studies
ℹ Use pattern in research: daily oral use; short-term human studies report hormone-marker changes, with effects on testosterone reported inconsistently across trials.
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.
fenugreek — PubMed search: fenugreek extract randomized controlled trial · NIH NCCIH — Fenugreek · ClinicalTrials.gov — 60 registered studies
ℹ Use pattern in research: studied as a standardized extract over 8–12 weeks; may interact with blood-thinning and blood-sugar medication — documented interaction, not advice.
maca root — PubMed search: Lepidium meyenii randomized trial · NIH NCCIH — Maca · ClinicalTrials.gov — 9 registered studies
ℹ Use pattern in research: studied for libido-related endpoints; research generally does not show testosterone changes — the two are often conflated in marketing.
These notes state where label numbers and marketing framing sit relative to published research — documentation for your own judgment, not medical advice. LookCloser does not advise for or against taking any supplement.
