Checked against public sources on August 31, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The barcode identity checks out · 716563912093. The barcode matches, so we are checking the right product rather than a look-alike.
“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.
The public sources did not settle the marketing promises on this label.
No named laboratory or lot-specific certificate was found for this exact product. No exact brand product page was available for a document check. 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.
