Choosing a Pharmacy
How do I spot fake Wegovy or Mounjaro pens?
By Kaiser Khan · Updated 12 August 2026
What is the safe buying checklist?
A legitimate UK supply path is boring: a GPhC-registered pharmacy, a structured consultation, and a pack that looks like a licensed medicine. 1) GPhC premises number on the website. 2) That number matches an active premises on pharmacyregulation.org. 3) A real consultation — not a skippable quiz. 4) Professional packaging with a patient information leaflet. 5) Traceable delivery to you, not a hand-off from a stranger. Pick My Pharmacy compares regulated treatment services; we do not sell pens. Desk-researched 12 August 2026.
Which offers should you treat as fake until proven otherwise?
Social-media ‘pens’, Telegram sellers, and websites that let you add Mounjaro or Wegovy to a basket with no health questions are high risk. So is a price far below the typical private UK range we publish on our Mounjaro and Wegovy comparison pages (editorial ranges last checked July 2026 — always confirm live pharmacy prices). A bargain that skips the prescriber is not a pharmacy service. See our guide on choosing a safe online pharmacy for the full register checklist.
What should you do if you already have a pen you do not trust?
Do not inject it. Keep the pen and packaging. Contact a pharmacist or GP, or call NHS 111 if you feel unwell (999 in an emergency). Report suspected fake medicines via the MHRA Yellow Card scheme and report the seller if you still have the site or account details. We cannot identify a pen from a photo in this article — that is a clinical and enforcement job, not a comparison-site job.
People Also Ask
Are cheap social media pens ever legitimate?
Treat them as high risk. Legitimate UK supply of these prescription-only medicines goes through registered pharmacies with consultations.
Can Pick My Pharmacy tell me if my pen is genuine?
No. We do not inspect pens or supply medicines. Use a GPhC-registered pharmacy, a clinician, and MHRA reporting routes.
Is a low price proof of a fake?
Not proof — but a price far below every GPhC-registered service we compare is a reason to stop and verify the premises, not a reason to pay faster.
