USPTO names Centera Bioscience Inc as the brand owner.
Rebuilt from public sources on July 22, 2026 · evidence availability is not a safety or effectiveness verdict.
USPTO lists Centera Bioscience Inc (['CORPORATION', 'LIMITED LIABILITY COMPANY']) in ['ARIZONA, USA', 'NEVADA, USA'] for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not …
The listing-image panel publishes an amount for each of its 1 declared row. That supports ingredient-by-ingredient review; it does not verify the contents.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Tongkat Ali Extract (Eurycoma longifolia) (root) (10% Eurycomanone by UPLC) | 100mg | — |
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.

This is the USPTO owner of the brand wordmark. It tells a shopper who is behind the brand, but does not by itself identify the manufacturer or prove where this product was made.
Review counts rose gradually. Written-review counts rose from 94 to 100 across the observed period. That describes count movement, not review authenticity or product quality. A variation family may share some public counts.

These links provide the public research context used alongside the captured panel. They do not establish safety, effectiveness, or product quality.
Can the testing claim be tied to a named laboratory and this product lot? Evidence that would settle it: lot-specific COA naming the laboratory and matching the product lot.
Confirmed evidence
These checks found support in the public record. They confirm specific facts, not the product as a whole.

Documented concerns
These are documented contradictions or claims that need more evidence. They are separate from missing data.
No contradictions or product-specific cautions were found at this check depth.
Unresolved public record
We looked for these signals but could not settle them from public sources. A gap is not a strike.
The listing claims third-party testing without naming any lab or certifier, so the claim can't be verified as stated.
The current image extraction retained 1 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.
Published sources describe how tongkat ali 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.
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.
Exact-listing history records written-review counts from 94 on 2026-02-24 to 100 on 2026-07-19 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
What to ask and check
Ask the brand or seller
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.
What is the product’s UPC or GTIN?
The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.
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.
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
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.
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.
