Does the marketing hold up?

The observed listing says it is tested, but names no lab or certifier. A testing badge without an issuer or report is a marketing claim, not evidence. Ask for the lab name and lot-specific report.

“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.
