How we verify pharmacies.
Every provider, checked against the live GPhC register, and how to check for yourself.
Why this matters.
Weight-loss injections are prescription-only medicines, and demand has made them a target for counterfeit sellers. The single most reliable check available to you is also the simplest: the GPhC register.
Our process
- We capture each provider's GPhC premises registration number.
- We check it against the live register, the entry must exist and resolve to registered pharmacy premises.
- Each profile links directly to the register entry, in the format
pharmacyregulation.org/registers/pharmacy/{number}. - Verification is re-run every time the site is updated. Providers we can't verify don't appear.
And the score? That's real customers talking.
The score you see on every profile is the provider's actual Trustpilot TrustScore, collected from its public Trustpilot page, most recently on 1 October 2026. We don't invent scores, adjust them, or accept payment to change them; we report what real customers wrote, link you to the reviews so you can read them yourself, and show “Not yet rated” where a provider is too new to have one. GPhC verification tells you a pharmacy is legal; the Trustpilot score tells you how it treats people.
Do it yourself: honestly, please do
Find the GPhC number in the footer or “about” page of any online pharmacy, then search it at pharmacyregulation.org. Check that the name and premises details match the site you're buying from. The MHRA's guide to buying medicines safely online is worth five minutes of your time too.
The standards we verify against, from the regulator itself.
Our register check is only useful because of what registration now requires. Here is what the GPhC changed in 2025, in its own words, and the enforcement picture that makes the check worth doing.
The General Pharmaceutical Council, the pharmacy regulator for England, Scotland and Wales, updated its guidance for registered pharmacies providing services at a distance. Weight-management medicines are now classed as needing additional safeguards: the prescriber cannot rely on an online questionnaire alone, must independently verify weight, height and BMI (by video or in-person consultation, clinical records, or contact with the GP or usual prescriber), and there must be timely two-way communication. Superintendent Pharmacists are now jointly responsible with pharmacy owners for meeting the guidance, and incentives to prescribers are barred.
"...should only supply a medicine if the prescriber has had an appropriate consultation."
The MHRA Criminal Enforcement Unit seized more than 5,000 illegal GLP-1 weight-loss products, disrupted more than 1,500 websites and social media accounts, removed more than 1,200 social media posts, and in October 2025 dismantled the first UK factory producing unlicensed weight-loss pens, in Northampton, where more than 2,000 tirzepatide and retatrutide pens were ready to ship alongside tens of thousands of empty pens and raw ingredients.
"Each and every one of those products was potentially dangerous to the public."
