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 2 declared rows. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Tongkat Ali Root Extract 200:1 | 1000mg t | — | |
| Tribulus Terrestris Fruit Extract | 20mg t | — |
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
Exact trademark owner identified
USPTO lists Double Wood LLC (LIMITED LIABILITY COMPANY) in PENNSYLVANIA, 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.
UPC independently corroborated
UPCitemdb resolves 859793007365 to "Tongkat Ali - 120 capsules, 1020 mg servings" (Double Wood Supplements) — consistent with this listing.
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.
Panel amounts are awaiting a clearer image read
The current image extraction retained 2 ingredient name(s) but no usable amounts. This is a LookCloser processing gap, not evidence that the brand withheld the numbers; dose arithmetic is withheld until the panel is re-read.
Research context is available for the listed ingredients
Published sources describe how tongkat ali, tribulus terrestris 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: Eurycoma longifolia randomized trial, NIH NCCIH — Herbs at a glance.
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.
180-day review-count history is on file
Exact-listing history records written-review counts from 1,175 on 2026-02-03 to 1,198 on 2026-07-09 (net +23). 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 “…20 Capsules - with 20mg Tribulus Terrestris (Third Party Tested) by Double Wood SUPPORTS EXERCISE ENDURANCE:…” | 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. |
| Benefit claim “…rrestris (Third Party Tested) by Double Wood SUPPORTS EXERCISE ENDURANCE: Tongkat and Tribulus hav…” | 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 |
|---|---|---|
| Tongkat Ali Root Extract 200:1 | shaded = doses used in studies (200 mg–400 mg) · bar = this label | 1 g — above the studied range |
| Tribulus Terrestris Fruit Extract | shaded = doses used in studies (250 mg–1.5 g) · bar = this label | 20 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.

Where it sells
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store doublewoodsupplements.com: 197 supplement products (+6 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.
Reference links for identification only — LookCloser has no affiliate relationships and earns nothing from any link on this page.
Related research & consistency
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.
