The MHRA reports that a Birmingham raid recovered over 12,000 fake retatrutide and tirzepatide pens, valued at approximately £2 million, plus packaging for around 30,000 more products. Retatrutide remains unauthorised in the UK. The seized products have not been assessed for safety, quality or effectiveness.

SHIFT’s take

What we think this could mean for you, and what remains uncertain.

This is an illegal-supply warning, not evidence that retatrutide has become an available treatment or that every pharmacy is implicated.

Known facts

The MHRA announced the seizure on 15 October 2026.
