Private UK GLP-1 clinics — what good looks like
Private prescribing of GLP-1 medicines in the UK is lawful when done correctly. Many online services do it correctly. Many cut corners. Here's how to tell the difference before you hand over money and medical history.
What a regulated private GLP-1 service must do
- UK-registered prescriber — a GP, specialist, or independent prescriber listed on the GMC, GPhC, NMC, or HCPC register. Their name and registration number should be findable.
- UK-regulated pharmacy — listed on the GPhC register (England, Scotland, Wales) or the PSNI register (Northern Ireland). The pharmacy registration number should be on the website. The MHRA / GPhC internet pharmacy logo should appear and link to the register entry. See how to check.
- Real clinical assessment — not a 60-second tick-box form. The prescriber should ask about medical history, contraindications, current medications, mental health, eating patterns, and expectations.
- Genuine product — UK packaging, batch number, expiry date, marketing authorisation holder details, and a Patient Information Leaflet in the box.
- Ongoing clinical access — review intervals, a route to contact the prescriber for side-effect questions, and a plan for stopping or changing dose.
- Complaints procedure — published, with the relevant regulator named.
What you should be told before you pay
- Who the prescriber is and what register they sit on.
- Which pharmacy is dispensing.
- Which product (Wegovy, Ozempic, Mounjaro) — and which dose strength.
- The titration plan and how side effects will be managed.
- Cost per month and what happens if dose changes.
- Cancellation / refund policy.
Cut-price services — what's being skipped
The reason some online services charge half what a properly run clinic charges is usually that they have skipped one or more of:
- Real clinical assessment time (a UK-registered prescriber's time costs money).
- UK-regulated pharmacy dispensing (sourcing from cheaper, unregulated channels).
- Ongoing clinical contact (no human to call when side effects appear).
- Genuine product (counterfeit or "compounded" alternatives).
- Complaints and follow-up infrastructure.
Sometimes the discount is genuine — efficient digital service, lower overheads. Sometimes it isn't. The checklist above is how to tell.
Red flags in private clinic marketing
If you see wording like this on a seller, clinic, or social-media advert, treat it as a warning sign rather than a benefit.
“Approved in 60 seconds — pen shipped tomorrow”
No real clinical assessment fits in 60 seconds. Either the assessment is being skipped, or the form is theatre.
“Our compounded version costs half the price of Mounjaro”
UK compounding rules are narrow. 'Compounded GLP-1' is rarely legitimate compounding; usually it's unregulated grey-market product.
“Cheapest Mounjaro in the UK — guaranteed”
Price is the wrong primary signal for prescription medicines. The cheapest source is often outside the regulated supply chain.
“Lose 10kg in 4 weeks or money back”
Trial averages don't support that timescale. Real prescribers don't guarantee outcomes.
“Skip the wait — start on the maintenance dose immediately”
Skipping titration steps materially increases GI side effects and isn't standard prescribing.
“Trusted by celebrities and influencers”
Celebrity endorsement is not clinical evidence and is unrelated to whether the service is properly regulated.
Questions to ask a private clinic before paying
These are starter questions you can adapt for a GP, specialist, pharmacist, or anti-doping advisor. The aim is to help you have a better-informed conversation — not to replace one.
- Who is the prescriber and what is their UK registration number?
- Which pharmacy is dispensing and what is their GPhC or PSNI registration?
- How is the clinical assessment carried out — what does the consultation include?
- What is your dose-titration protocol?
- How do I contact the prescriber between reviews if I have a side-effect concern?
- What is your complaints procedure and who is the regulator?
- What is your refund / cancellation policy?
- Where in the regulated supply chain is the product sourced?
