Regulation & market

Counterfeit

A product deliberately misrepresented as a genuine one — wrong ingredient, wrong quantity, or no active ingredient at all.

In plain terms

Counterfeits are not only a grey-market problem. FDA has seized counterfeit Ozempic that had entered the legitimate U.S. supply chain, bearing an authentic lot number, with counterfeit needles whose sterility could not be confirmed.
