CompareTheJab helps you research UK weight-management providers, treatment pricing, clinical support and safety information in one clear place.
Compare treatments
The medication is the easy part. Choosing between dozens of providers offering the same pen at wildly different prices — that's what we're here for.
Semaglutide · GLP-1 · Novo Nordisk
Tirzepatide · GLP-1/GIP · Eli Lilly
We'll let you decide which one that is — but first, you need the full picture.
How we work
Every provider claims to be the best. We checked. Here's how we actually compare them.
Every provider on our comparison pages is checked against the GPhC register before we list them. Prescribing services are CQC-verified in England. No registration, no listing.
Prices in this market shift constantly. We check and update every Monday. What you see reflects the market this week, not six months ago. Always verify directly before ordering.
A budget pharmacy and a dietitian-led programme are not the same thing. We separate them clearly, explain what each actually includes, and let you decide what matters for your situation.
Each provider gets a plain-English note on what makes them worth considering — and what to watch out for. We're not here to sell. We're here to inform.
Why us
We'll let you decide. But first, you need the full picture — which means knowing the difference between a clinical programme and a dispensing questionnaire, even when both call themselves a "service".
No paid placements. No sponsored rankings. Just a straight comparison of what each provider actually offers, what it costs at every dose, and what the clinical evidence says about the drugs themselves.
How we compare providers →Our approach
The four things we hold to in everything we write and build.
Our guides are medically reviewed. We cite evidence, state when something is unclear, and don't dress up uncertainty as fact.
Every word on this site is here because it helps you make a better decision. Nothing more. We cut the waffle so you don't have to.
Providers cannot pay to rank higher. We may earn a referral fee from some links — this is clearly disclosed and does not affect our editorial judgement.
This is a significant decision for most people who make it. We write with that in mind: plain language, no shame, no hype.
The medication
GLP-1 receptor agonists work by telling your brain you're full and making your stomach take its time. The difference between them — and between the 40-odd providers selling them — is what we exist to explain.
Our comparison pages cover every dose, every provider, and every price. Updated every Monday. No paywalls, no registration required.
