Does the marketing hold up?
Testing claimed — documentation not found. The observed listing and a related brand product page both claim third-party testing. Neither names the laboratory or links a product- or lot-specific report. …

Marketing claims, checked
The checks, one by one
The public sources did not settle the marketing promises on this label.
◐Partly confirmed2
“supplement is made in the USA in a GMP compliant facility and independently lab verified and tested for”
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.
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently2
“supplement is made in the USA in a GMP compliant facility and independently lab verified and tested for”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
“tested for”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. A related brand page repeats a testing claim but names no issuer; its UPC is not published. 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.
We looked and found no public proof. That does not count against the product.

What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
CheckedCan you trust the review pattern?
Reviews rose from 11 to 23 between September 23, 2025 and August 16, 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 11 to 23 between September 23, 2025 and August 16, 2026. The largest rise inside any single 30-day window was about 2, so the count moved in steps rather than in one burst.

- No FDA recall matched this brand in the current search.
- Panel amounts still need a clearer source image.
- We have not found a public label filing for this exact product.
- Barcode checksum is valid; no independent product record was found.
- Brand ownership is not settled in this record.
These are evidence gaps, not strikes against the product.

Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.

The observed listing and related brand page repeat 400 mg. That confirms cross-page consistency of the published claim, not the product contents.
