Checked against public sources between July 25 and July 28, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Every ingredient shows its amount · 18 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
“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.

We read 18 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
The public sources did not settle the marketing promises on this label.
Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.
No named laboratory or lot-specific certificate was found for this exact product. A related brand page names no testing issuer and links no product-bound report; 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.
Headlines first. Open evidence only when you want the source trail.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
