More than 12,000 counterfeit weight-loss pens, worth an estimated £2m, have been seized in a raid on an industrial unit.
The fake goods were found at a “filthy warehouse” on an estate in Birmingham, according to the Medicines and Healthcare Products Regulatory Agency (MHRA).
“There is no guarantee of what they contain or whether they have been contaminated with harmful substances,” said the agency. .
Packaging for about 30,000 extra products was also discovered.
The MHRA said the pens contained fake versions of the drugs retatrutide and tirzepatide, medicines used for weight loss.
A BBC investigation previously found vials purporting to be “reta” as it’s become known, were being sold in the UK in gyms, nail and beauty salons, hairdressers, on social media and even by flower sellers on the street.
