Everything you need to know about accessing Mounjaro for weight loss treatment.
Key takeaways
- Mounjaro combines GLP-1 and GIP hormone actions, making it highly effective for weight loss by reducing appetite, promoting fat loss, and improving blood sugar levels. Clinical trials show up to 20.9% body weight loss over 72 weeks.
- Both medications are effective for weight loss, but Mounjaro's dual-action mechanism may offer slightly better results compared to Wegovy's GLP-1-only approach. Mounjaro also has higher dosing levels, starting at 2.5mg and increasing to 15mg.
- Mounjaro is available on the NHS with strict eligibility criteria, or more readily through private programs like Juniper's Weight Reset Programme, which combines medication with coaching and lifestyle support for sustainable weight loss.
Weight loss medications have become more popular and accessible over the last few years and one of the latest to gain more visibility is Mounjaro. This medication, which contains the active ingredient tirzepatide, can be used alongside lifestyle changes to lose weight and the results are incredibly impressive.
So, how can you buy Mounjaro in the UK? And how does Mounjaro stack up against Wegovy, another weight loss medication? Let's explore everything you need to know about accessing Mounjaro for weight loss treatment.
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.
Wegovy vs Mounjaro for weight loss
There are no published head-to-head trials comparing Wegovy and Mounjaro at this stage, but we can compare the respective clinical trials of these weight-loss injections.
A 2023 study found that patients using Mounjaro reached 20.9% body weight loss at 72 weeks, while another study found that Wegovy patients experienced an average weight loss of 14.9% at 68 weeks [2][3].
There is also a difference between the dosages of the medications, with Mounjaro a higher dose, starting at 2.5mg and going up to 15mg. Wegovy, on the other hand, starts at 0.25mg and goes up to a maximum dose of 2.4mg [4].
These medications can help you lose weight and improve your health, when used with lifestyle and behavioral changes.

Can you get Mounjaro on the NHS?
Yes, Mounjaro is available on the NHS for weight loss. As of late June 2025, Mounjaro (tirzepatide) can be prescribed by GPs in England but availability is restricted, with the initial rollout planned to reach 220,000 people over 3 years.
As such, officials are advising individuals to refrain from contacting their GPs about the weight loss medication unless they meet the following criteria:
Year 1
- BMI ≥ 40 (or ≥ 37.5 for some ethnic groups)
- 4 or more weight-related comorbidities (e.g. type 2 diabetes, high blood pressure, sleep apnoea)
Year 2
- BMI 35 to 39.9
- Still require 4 or more co-morbidities
Year 3
- BMI ≥ 40
- 3 or more co-morbidities
Alternatively, you can access Mounjaro more readily (if eligbile) through private telehealth clinics like Juniper. You simply need to meet a few eligibility requirements, including body mass index, which you can check via our website right now.
Alternatives to Mounjaro
Mounjaro isn't the only weight loss injection available in the UK. Wegovy is another great option for those wanting to lose weight and help remedy weight-related health problems.
Wegovy mimics the GLP-1 hormone, which helps to regulate blood sugar levels and lets your brain know when you're full and that it's time to stop eating, which helps you lose weight.
A clinical study from 2021 looked at 1,961 obese and overweight adults who were randomly assigned Wegovy or a placebo. After 68 weeks, those taking Wegovy lost an average of 15.3kg, whereas the placebo group lost an average of 2.6kg [3].
We also offer Wegovy as a medication option on the Weight Reset Programme. Whether you choose Wegovy or Mounjaro, our programme has 3 core focuses:
A biological reset
We prescribe the latest available weight loss medication which targets the receptors in the brain that control your appetite. The medication works to lower your body’s ‘set point’, which is the weight it fights to maintain at a biological level. This helps you to lose weight.
A behavioural reset
Our clinicians, health coaches and community supports you every step of the way. During our programme you’ll learn sustainable nutritional, exercise and lifestyle choices, tracking your progress to help you form long-term habits that stick. This will not only help you lose weight but keep it off for good.
Our community
Research shows that people in group communities achieve greater weight loss than those who do it alone. That’s why we’re here — we’re dedicated to helping women to make lifestyle changes that are often difficult to achieve on their own.
