Scan the QR code on your KEIFEI box to confirm it's the official KEIFEI code — then check the four physical markers that prove the product itself is genuine.
Point your camera at the QR code on your KEIFEI box. We'll confirm whether it's the genuine KEIFEI code.
The QR confirms you're on the official KEIFEI page. These four physical markers prove the product itself is genuine — check every one.
A KF-prefixed lot number printed on the vial or blister, repeated on the box, and matching the Certificate of Analysis — all three identical.
The crimp cap is embossed — pressed into the metal, not printed on top. A flat or unbranded cap, or one already loose, is a red flag.
The correct printed carton: right logo and colours, product name and strength, and a batch-printed expiry. No blur, no spelling errors, no missing panel.
A Certificate of Analysis from an independent lab, matched to your lot number, with lab letterhead, stamp and contact details so you can verify it.
If any marker is missing or inconsistent, treat the product as unconfirmed. The full breakdown — with an annotated vial and a side-by-side counterfeit comparison — is in the authenticity guide.
