At Moulton Grange, a stately Georgian country house in Northamptonshire renowned for its lavish weddings and corporate events, a sinister secret was uncovered on 28 May by officers from the Medicines and Healthcare products Regulatory Agency (MHRA). The property, valued at £2.2 million when purchased in 2017, has been revealed as the site of the UK's largest seizure of illicit weight-loss injections, with approximately 12,000 doses of unregulated pharmaceuticals seized.
The raid led to the arrest and subsequent release of two 29-year-old men, who are believed to be part of an organised criminal network involved in producing and distributing these unlicensed medicines. Moulton Grange boasts a cream-white Georgian facade, chandeliers, dark wood panelling, and sprawling grounds across 28 acres, but its reputation has been marred by this shocking discovery.
According to investigators, this operation marks the first instance of an illicit weight-loss jab being produced under its own brand name, rather than counterfeit versions of established medications. The packaging seized from Moulton Grange was described as 'sophisticated' and 'authentic looking', which could heighten the risk to consumers. Among the items recovered were syringes labelled as tirzepatide and retatrutide – while tirzepatide is a legitimate medication sold under the brand name Mounjaro by Eli Lilly, the MHRA confirmed that the seized products were not manufactured by the firm.
The seized products bore the 'Alluvi' label, matching labels discovered in an earlier MHRA warehouse raid in Northamptonshire in October 2025. Trademark registrations for 'Alluvi' and 'Alluvi Healthcare' were filed in April 2026 by a company based on an industrial estate in Northampton, but any direct link between this firm, the seized drugs, and Moulton Grange remains unclear.
The MHRA has issued a stark warning to the public, emphasising that prescription-only medicines should only be obtained through registered pharmacies with a valid prescription. The agency cautioned that 'products obtained outside legitimate supply chains offer no guarantees about their safety, quality or authenticity.'
This incident highlights the growing trend of black market weight-loss drugs, driven by high demand for legitimate treatments like Ozempic and Wegovy, which often face supply shortages. For UK households, falling victim to such illicit schemes can have significant economic consequences – unregulated drugs pose a substantial risk due to their unknown safety, quality, or authenticity.
