Wegovy and Mounjaro: What the Clinical Evidence Shows
Wegovy (semaglutide) and Mounjaro (tirzepatide) are prescription GLP-1 receptor agonist injections. They work on the hormones that control appetite and fullness, so you feel satisfied on less food.
In the SURMOUNT-1 trial, people on the highest Mounjaro dose lost up to 20.9% of their body weight over 72 weeks. In the STEP-1 trial, people on the highest Wegovy dose lost up to 14.9% over 68 weeks. Both were taken alongside diet and exercise changes.
Here's the part that matters: food noise is biology, not a character flaw. Most diets fail because they ask you to out-willpower a signal your body fires on its own. This medication turns that signal down.
How the GLP-1 Mechanism Works
- GLP-1: slows digestion and helps you feel full sooner and for longer
- GIP (Mounjaro only): supports how your body uses insulin and processes fats
- Food noise reduction: quiets the inner monologue about what's in the cupboard
- Once-weekly dosing: one pen, four doses, same day each week

Who's Eligible for an Online Weight Loss Clinic?
You don't need a GP referral or an in-person appointment. If you're an adult whose body mass index is in the right range, one of these treatments may suit you.
- A body mass index (BMI) of 30 or above
-
Or a BMI of 27 or more, with weight-related
health conditions such as:
- Type 2 diabetes
- High blood pressure
- High cholesterol
Who Should Not Use These Injections
- A personal or family history of thyroid cancer (particularly medullary thyroid carcinoma)
- Previous pancreatitis or severe stomach pain from GLP-1 medications
- Pregnancy, breastfeeding, or being under 18 or over 75
- Taking insulin, sulfonylureas, or certain other diabetes medicines
If your assessment shows these aren't suitable, we'll say so. We'd rather lose a sale than prescribe something unsafe.

Straight Answers About Online Weight Loss Clinics
What is an online weight loss clinic?
A clinic that assesses you remotely, then prescribes and posts your medication. You fill in an online medical form, a UK-registered clinician reviews it, and a GPhC-registered pharmacy ships your treatment to your door. No waiting room, no face-to-face appointment needed.
How does an online weight loss clinic work?
You complete a secure medical questionnaire covering your weight, height, and medical history. A GMC-registered clinician reviews your answers, usually within 24 hours on weekdays. If you're suitable, they write a prescription and a pharmacy delivers it in cold-chain packaging.
Is it safe to buy weight loss injections online?
It is, if you use a regulated UK provider. Look for a named prescriber, a verifiable GPhC registration number, and a real medical assessment before any prescription. Avoid sellers with no questionnaire or prices far below the usual range.
Am I eligible for Wegovy or Mounjaro?
Usually, you need a BMI of 30 or above, or a BMI of 27 or more with a weight-related condition like type 2 diabetes, high blood pressure, or high cholesterol. You also need to be between 18 and 75. A clinician confirms this during your assessment.
How much does an online weight loss clinic cost?
At Chelsea Slimming Clinic, Wegovy starts at £129.99 a month and Mounjaro at £174.99 a month. Every price includes the assessment, prescription, medication, and delivery. There are no hidden fees at checkout.
Can I get Wegovy or Mounjaro on the NHS?
Yes, in limited cases. NICE has approved both for eligible patients, but the NHS rollout is phased and tightly restricted. Most people currently access these treatments through a private online clinic.
Do the injections need to be refrigerated?
Yes, unused pens must be kept between 2°C and 8°C before first use. We ship in insulated Woolcool packaging with gel ice packs. After your first dose, the pen can stay at room temperature for up to 30 days.
Which weight loss injection is right for me?
It depends on your response, tolerance, and medical history. Wegovy works on one hormone; Mounjaro works on two and showed slightly higher average weight loss in trials. Your clinician will recommend the better fit during your assessment.
