We looked for these signals but could not settle them from public sources. A gap is not a strike.
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 magnesium, tongkat ali, tribulus terrestris, horny goat weed have been studied. This is ingredient context only; the record does not establish that this product delivers the studied dose or outcome.

This category has documented FDA fraud 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).
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Premier Research Labs LLC recalled a different or not-exactly-bound product on 2022-06-15: “Product spoiling over time; spoilage visible beneath lid/closure upon opening.” (status: Terminated). The recalled product was: “AloePro Dietary Supplement Made With Organic ALOE VERA LIQUID 16 FL Oz. (475 mL) PREMIER RESEARCH LABS UPC Code: 80773500137 packaged in plastic HDPW bottles” — not necessarily the product on this page. Verify at FDA’s recall database.
No label filed with NIH's public catalog
The NIH Dietary Supplement Label Database has no matching label yet. Ingestion lags the market — recorded as a gap, 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
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.
2
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.
3
Were the endorsing professionals compensated, and what exactly did they review?
An endorsement can be genuine and still not mean the product was tested. Ask whether they reviewed the formula, the manufacturing, or only the marketing.
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 663387832871.
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.
