Over 12,000 fake pens, and packaging for 30,000 more
What happened
On 14 October 2026 the Medicines and Healthcare products Regulatory Agency (MHRA) and West Midlands Police raided an industrial unit in Birmingham. They announced what they found the next day, 15 October. Inside were more than 12,000 counterfeit weight-loss injection pens, labelled as retatrutide and tirzepatide. Officers also recovered packaging for around 30,000 more products. The MHRA puts the total value at roughly £2 million. Tim Duffield, Head of Intelligence at the MHRA's Criminal Enforcement Unit, described the site as a “filthy warehouse on an industrial estate”. He said the products “have not been assessed for safety, quality or effectiveness”, so there is no way of knowing what is in them or whether they have been contaminated. He also made a point about one of the two medicines named on the labels. “Retatrutide has not been authorised for use in the UK,” he said. It is still going through clinical trials, and supplying it outside a legitimate trial is illegal here. Tirzepatide is different. It is a licensed, prescription-only weight-loss and diabetes medicine in the UK, which is exactly why criminals copy it. A fake pen with a real-looking label is easier to sell than something nobody has heard of. No arrests from this particular raid have been reported. The MHRA says it is “tackling the organised criminal gangs whose illegal trade in unauthorised medicines” puts people at risk. This is not a one-off. The MHRA lists a run of similar operations. In May 2026 two people were arrested after a raid on a country estate, where about 12,000 doses were recovered. In February 2026 around 2,000 doses were seized as they waited to be posted out, along with manufacturing equipment and ingredients. And in October 2025 the agency dismantled what it described as the first illicit weight-loss medicine production facility found in the UK, seizing 5,000 pens.
Why this matters
Weight-loss injections have become one of the most wanted medicines in Britain. Demand outstrips what the NHS can offer, private prescriptions cost money, and waiting is frustrating. That gap is where the fakes live. The appeal of an unregulated seller is obvious: no appointment, no questions, cheaper, and it arrives in the post. The problem is that everything which makes a real pharmacy slow is also what makes it safe. A registered pharmacy has to know who made the medicine, how it was stored, and who you are. A warehouse on an industrial estate does not. There is also a quieter point in these figures. The packaging for 30,000 more products matters as much as the 12,000 pens. It tells you this was a production line, not a stash – someone was planning to keep making these. Seizing 12,000 pens stops those 12,000 pens. It does not stop the demand that made them worth making. If you have bought a weight-loss pen from somewhere other than a registered pharmacy, this is a reason to stop using it and speak to a pharmacist or GP.
What the evidence actually says
The honest answer about what is in a counterfeit pen is: nobody knows. That is the whole problem, and it is what the MHRA keeps saying. These products are not tested, so there is no list of ingredients to check. But we do know what has been found before, and it is worth knowing. On 26 October 2023 the MHRA warned that fake Ozempic and Saxenda pens had been found in the UK. It had received reports of a very small number of people being taken to hospital after using them. The side effects reported – including hypoglycaemic shock and coma – led the regulator to say the pens may have contained insulin rather than the semaglutide named on the label. The MHRA had seized 369 potentially fake Ozempic pens since January 2023, and none at all before then. Its advice was blunt: if you bought a pre-filled weight-loss pen online, do not use it, and report it. That is the realistic risk. Not a weaker version of the drug you wanted, but a different drug entirely, at a dose nobody chose, injected by someone who has no idea it is there. Insulin in a person who does not need insulin is a medical emergency. On the other side of the ledger: the genuine medicines work, and they are available legally. The problem is not the drug. It is the supply route.
Qurexa perspective
We are a delivery company, so we will say the obvious thing carefully: the convenience of something turning up at your door is not the same as it being safe. The two often get bundled together online, and they should not be. What makes a delivery safe is what sits behind it. A prescription written by someone who has assessed you. A registered pharmacy that can account for where every box came from. A cold chain that is actually maintained, which matters a great deal for injection pens. A record, so that if a batch is recalled, someone can find you. An unregulated seller offers the parcel without any of that. It looks like the same service. It is not. If you are already on a weight-loss injection through a legitimate route and the cost or the hassle is tempting you elsewhere, talk to your pharmacist first. There are usually options worth knowing about before you take a risk with an unknown pen.
Practical advice
Get weight-loss medicines only from a registered pharmacy, against a valid prescription. In Great Britain every pharmacy, including online ones, must be registered with the General Pharmaceutical Council, and you can check a pharmacy on its register. Treat these as warning signs: no prescription needed, no consultation, prices far below the going rate, sales through social media or messaging apps, and payment by bank transfer or cryptocurrency. Use the MHRA's #FakeMeds website if you want to check before you buy. It is written for exactly this situation. If you already have a pen from an unregulated source, do not inject it. Speak to a pharmacist or your GP. Know the emergency signs. If someone who has used one of these pens becomes shaky, sweaty, confused, very drowsy or unconscious, that can be dangerously low blood sugar. Call 999. Tell the paramedics what was injected and bring the pen if you can. Report it. If you think you have had a side effect from any medicine, tell your doctor, pharmacist or nurse, and report it to the MHRA's Yellow Card scheme at yellowcard.mhra.gov.uk. If you have been sold something you believe is fake, you can report that to the MHRA too. Cases like the Birmingham one are built partly from what members of the public pass on.
What to know
On 14 October 2026 the MHRA and West Midlands Police seized more than 12,000 counterfeit retatrutide and tirzepatide pens from an industrial unit in Birmingham, along with packaging for around 30,000 more products. The haul is valued at about £2 million. It was announced on 15 October. Retatrutide is not authorised in the UK at all. Tirzepatide is, on prescription – which is why it gets copied. Counterfeit pens are untested, so their contents are unknown. When UK fakes have been analysed before, some contained insulin, and people were hospitalised. Buy only from a registered pharmacy with a valid prescription. If you have a pen from anywhere else, do not use it – speak to a pharmacist.
