“CERTIFIED”
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.

Does the marketing hold up?
Testing claimed — documentation not found. The observed listing claims third-party testing without naming a lab or certifier. No product-bound report is saved, so the claim cannot be verified as stated. …

Is it the real thing?✓Barcode matches outside 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.

The public sources did not settle the marketing promises on this label.
◐Partly confirmed1
Ingredient research can support context, but it is not a trial of this exact product.
?Couldn’t verify independently2
“PARTY LAB”
Evidence →No named laboratory or lot-specific certificate was found for this exact product. The exact brand page names no testing issuer and links no product-bound report. 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.
“in the”
Evidence →“Made in USA” can describe only final bottling. Ingredient-sourcing records were not located for this product.
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.
CheckedIs the label honest?
Every ingredient shows its amount · 19 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.

The barcode identity checks out · 724195275059.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
The brand's store lists this exact barcode as “Marine Collagen Peptides Powder” (variant: 1.5 lb) — identity confirmed across retailer listings.

- No FDA recall matched this brand in the current search.

Review pages
Does the brand page tell the same story?
Brand page 4.50/5 · retailer 4.4/5inspect
The exact brand page is higher by 0.10 points. The brand page publishes 43; the retailer surface shows 2,597. Different systems can collect different review pools, so this is a signal to inspect, not proof that reviews were manipulated.
The brand page did not expose a complete star-by-star breakdown in the captured structured data, so LookCloser cannot test whether lower-star reviews were omitted. Source: exact barcode-bound brand product page · retailer surface · counts do not prove authenticity.
