MHRA raids illegal weight-loss jab production line worth more than £250,000
The Medicines and Healthcare products Regulatory Agency (MHRA) has seized more than 2,000 unlicensed weight-loss pens, plus raw chemical ingredients in what it says is “believed to be the largest single seizure of trafficked weight-loss medicines ever recorded by a law enforcement agency worldwide”.
The MHRA has confirmed to The Pharmaceutical Journal that the warehouse in Northampton was raided by officers from the agency’s criminal enforcement unit (CEU), supported by Northamptonshire Police, as part of an operation over the course of two days beginning on 22 October 2025.
Officers found “tens of thousands of empty weight-loss pens ready to be filled, raw chemical ingredients and more than 2,000 unlicensed retatrutide and tirzepatide pens awaiting dispatch to customers”, with the contents of the pens “still being analysed”, it said.
The MHRA explained that the street value of the finished weight-loss products alone is estimated to be more than one-quarter of a million pounds.
Officers also recovered “large amounts of sophisticated packaging and manufacturing equipment”, as well as £20,000 in cash that they suspect to be linked to medicines trafficking, according to the agency.
The site is the first illicit production facility for weight-loss medicine discovered in the UK.
