Where can you buy Mounjaro online in the UK?

We know sudden medication price rises can be stressful and disruptive, especially when you’ve built momentum with your weight loss journey.

From 1 September 2025, Eli Lilly, the manufacturer of Mounjaro (tirzepatide), will increase its UK list price to align with other developed countries. This nationwide change applies to providers including pharmacies, private clinics, and digital platforms.

In response, we’ve lowered the price of our Wegovy programme by 25%, and we’re making it easier for patients to switch without starting over, so that effective treatment remains within reach for as many people as possible.

Mounjaro vs Wegovy for weight loss

Both Mounjaro and Wegovy are once-weekly GLP-1 injections that work by reducing appetite and supporting weight loss. The key difference is: Wegovy contains semaglutide, a GLP-1 that’s been used by over 8 million people worldwide and studied in more than 39,000 clinical trial participants. Mounjaro contains tirzepatide.

Both of these medications are considered the gold standard when it comes to aiding weight loss efforts. Thus far, the two medications haven't been directly compared to each other in medical trials.

It's long been thought that Mounjaro leads to more significant weight loss outcomes than Wegovy but with recent research, that is changing.

In clinical trials, patients on the highest possible dose of Wegovy lost up to 20.7% of their body weight, compared to 20.9% with Mounjaro at its highest dose — showing that both can be highly effective when used consistently and with the right support [6][7]. This higher dose of Wegovy isn’t available just yet, but it’s expected to launch in the UK soon.

With Juniper, Wegovy is delivered as part of a complete programme that includes expert care, coaching, and tracking tools — to help you get the most from your treatment.

Can I switch from Mounjaro to Wegovy?

Yes! It is both safe and straightforward to switch from Mounjaro to Wegovy. To begin, please contact your healthcare provider to discuss the transition process.

If you've decided to move medication providers, you can inform your new prescriber of what weight loss medications and dosages you're using and they'll be able to advise you on next steps.

At Juniper, you simply need to answer some quick questions about your medical history and goals, then choose whether to continue on your current medication or switch to an equivalent dosage in the same trusted GLP-1 class of medications.

It's important to note that Wegovy and Mounjaro aren't interchangeable medications, so there is a short period of time where you come off one before starting the other. However, we only require a 7-day gap between your last Mounjaro dose and your first Wegovy dose — unlike most providers, who require 28 days.

And, if you've recently been on Mounjaro, you'll likely be able to start Wegovy at a higher dose, rather than beginning from scratch. Your Juniper clinician will review your treatment history and be able to advise on your circumstances.

Juniper’s clinical switching protocol is designed to make the change simple and safe:

• ‍Review — Your clinician assesses your treatment history and dose tolerance.‍
• Match — If eligible, you start on an equivalent high dose to avoid losing progress.‍
• Transition — Only a 7-day window is required between your last Mounjaro dose and your first Wegovy dose (most providers require 28 days).‍
• Support — Pharmacist check-ins, dose adjustments, and lifestyle guidance keep you on track.

What is Mounjaro?

Mounjaro is a dual-action treatment that mimics both the GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) hormones, making it highly effective for weight loss.

The medication, which includes the active ingredient tirzepatide, decreases your appetite by increasing feelings of satiation.  

Mounjaro is administered once a week via a subcutaneous injection — this sounds intimidating but it's the most effective way for the medication to do its job. This delivery method means the medication is diffused slowly, sometimes over 24 hours, at a sustained rate of absorption [1].

The medication is injected under the skin, into the subcutaneous fat. The best injection sites are the stomach, thigh or upper arm.

How does Mounjaro work for weight loss?

Unlike Wegovy, which mimics the GLP-1 hormone to increase feelings of fullness and delay gastric emptying, Mounjaro combines the action of GLP-1 with GIP, which also works to promote fat loss and block fat gain.

By combining the effects of both GLP-1 and GIP agonists, this treatment is more effective at promoting weight loss by controlling appetite while also impacting the pathways that lead to fat loss.

In simple terms: Mounjaro helps to make you feel less hungry, which in turn, means you feel fuller far more quickly, assists with reducing cravings, helps improve blood sugar levels and stimulates the breakdown of fat.

Research has also shown tirzepatide could help lower high blood pressure. A clinical trial of nearly 500 adults living with obesity found that tirzepatide significantly lowered their blood pressure after taking it for roughly 36 weeks [5]. So, weight loss isn't the only benefit you may experience when taking tirzepatide.
