“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?
Ingredient amounts are hidden inside “Keratin Proprietary Blend”. A blend total may be legal, but it prevents you from knowing whether any individual ingredient reaches a meaningful amount.
Is the dose real?✓Listing and panel agreeboth say 10,000 mcg of Biotin
What a serving costsNo price found for this exact barcode
Is it tested?Claimed — no lab or certificate found
Who’s behind it?🇺🇸Arsene, Mihaela-Georgianaindividual · USA
Is it the real thing?No barcode publishedso it can’t be matched against certification, recall or other retailer 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.

“STRENGTH FORMULA: Packed with Biotin, Collagen, Keratin, Hyaluronic Acid, and B-complex Vitamins supplement to promote healthy hair growth, skin…”
Evidence →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.

Evidence →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.

What is worth knowing.
Headlines first. Open evidence only when you want the source trail.
CheckedCan you trust the review pattern?
Reviews rose from 0 to 94 between October 3, 2025 and August 23, 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 0 to 94 between October 3, 2025 and August 23, 2026. The largest rise inside any single 30-day window was about 15, so the count moved in steps rather than in one burst.

Research behind the findings
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.
Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 1 g of collagen peptides per serving. Studies we found used 2.5 g–15 g a day, so this sits below that range.
0studied 2.5 g–15 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
