“Facility”
Evidence →“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.

Is the dose real?Panel read — dose not verified4 ingredients listed; no advertised amount we could confirm against them
What a serving costsNo price found for this exact barcode
Is it tested?No testing claim made
Who’s behind it?USPTO lists 2 owner recordssame brand name, more than one registrant — we don’t choose between them
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer records
Trouble on record?✓No recalls found
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.

Registered owner records: XTEND-LIFE HOLDINGS LIMITED · XTEND-LIFE GROUP LIMITED
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources
USPTO returned multiple live supplement-class records for the exact brand wordmark: XTEND-LIFE HOLDINGS LIMITED, XTEND-LIFE GROUP LIMITED. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Locked evidence record →Open the full source-linked findingCheckedIs the label honest?
Every ingredient shows its amount · 4 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingCheckedCan you trust the review pattern?
Reviews rose from 5 to 26 between May 26 and August 17, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 5 to 26 between May 26 and August 17, 2026. The largest rise inside any single 30-day window was about 16, so the count moved in steps rather than in one burst.
