You can buy Mounjaro online, but should you?
While you may feel tempted by fast, online access to Mounjaro, buying Mounjaro online can be dangerous and expensive.
Counterfeit weight loss medication is on the rise and has been found to contain dangerous and toxic ingredients. There are also serious risks if you take Mounjaro without proper medical supervision. Plus, buying Mounjaro privately could cost you at least £1,500 each year.

Weight management programmes like Oviva, which are accredited by the NHS, are a safe way to access prescription weight loss injections. Our two-minute survey can tell you if you’re eligible.

What is Mounjaro?
Mounjaro is a type 2 diabetes and weight loss medication. It contains the active ingredient tirzepatide and has been approved for use by the NHS as a weight loss treatment since December 2024. However, it’s been possible to purchase Mounjaro online for longer.
Tirzepatide works in two ways, mimicking the GLP-1 and GIP hormones your body releases after eating. This helps regulate blood sugar, reduce appetite, and increase feelings of fullness. While Mounjaro doesn’t directly burn fat, it helps you feel satisfied with smaller portions, which can support weight loss over time.
Mounjaro is a prescription-only medication intended for people with weight-related health issues or type 2 diabetes. It’s not a cosmetic treatment, and you must meet specific health criteria.
Why do people buy Mounjaro online?
There are three main reasons why some people who want Mounjaro buy it online:
Convenience
One of the biggest reasons people may choose to buy Mounjaro online is for the perceived convenience, especially in avoiding NHS waiting lists or in an attempt to get around the eligibility criteria that regulated providers follow. But that comes with significant risks.
Buying Mounjaro or other weight loss treatments online, without medical supervision, can be dangerous. These medications aren’t suitable for everyone and can interact with other treatments or health conditions in ways that put your health at serious risk.
Without proper assessment and guidance, you won’t know if it’s safe for you—or if what you’re buying is even genuine. The safest way to access Mounjaro is through an accredited weight management programme, where medical experts ensure your safety.
The UK Government has warned about the risks of adverse drug reactions specifically linked to GLP-1 receptor agonists, such as Mounjaro, when taken without medical supervision. They can cause serious side effects, including severe gastrointestinal complications.
Without proper guidance from a healthcare professional, the risks increase significantly.
Affordability
Some people may turn to unregulated sources to buy Mounjaro online in the UK, believing it to be a cheaper option. However, this comes with serious risks—even life-threatening ones.
When purchasing from an unregulated source, there’s no guarantee you’re receiving genuine medication. Some products contain harmful or unknown ingredients, putting your health in danger. Without medical supervision, there’s also a risk of taking the wrong dose, which can lead to severe complications.
A BBC investigation uncovered cases of people in the UK being hospitalised after taking what they thought were weight loss medications from unverified sellers.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued warnings against buying weight loss medications from unregulated sources.
Misuse
Some people are tempted to buy Mounjaro online due to misconceptions about its use or a desire to obtain a “quick fix” for weight management issues. However, Mounjaro and other similar treatments for obesity are not standalone solutions.
Weight loss medications need to be paired with sustainable lifestyle changes based on diet and activity levels. Without this, people often find it difficult to keep weight off after you finish treatment.
Mounjaro and all other prescription weight loss medications are not suitable as cosmetic weight loss treatment – they’re for people with an obese BMI (35) and weight-related health conditions.
Mounjaro, obtained from a regulated source and provided with medical supervision, is effective for weight loss, but long-term weight management requires a holistic approach. A weight management programme like Oviva can equip you with the skills and knowledge to make lasting changes to your behaviours and establish healthy habits.
Buying Mounjaro online comes at a price…
Mounjaro is a highly effective medication for weight loss and type 2 diabetes, but it can be expensive, especially when purchased privately online.
Many people find the ongoing costs difficult to sustain in the long term.
The cost increases significantly as you progress from the starting dose to the maintenance dose.

| 12.5 mg | £122.00 | Weeks 17 to 20 | £122.00 |
| 15 mg | £122.00 | Weeks 21 to 52 | £976.00 |
Total annual cost: £1,496.00
The dangers of buying Mounjaro online
Buying Mounjaro online carries several serious risks, and it’s essential to take these risks seriously to avoid putting yourself in danger.
Lack of medical supervision
You should have a professional medical assessment before taking Mounjaro. This determines your eligibility and can ensure you avoid unpleasant or dangerous interactions with other medications or health conditions.
Medical supervision is also crucial for understanding and managing the side effects of Mounjaro. Only a healthcare professional can accurately assess whether it’s an appropriate treatment for you based on your individual circumstances.

Unsafe dosage and misuse risks
There are also risks associated with unsafe dosage and misuse if you buy Mounjaro online.
A BBC investigation found beauty salons on high streets in Manchester and Liverpool selling weight loss medications and providing inaccurate and unsafe information about dosing.
This included telling an investigator it’s not dangerous to take too much of the weight loss drug semaglutide when, in fact, you can overdose if you take too much.
When taking Mounjaro, you’re supposed to start at a low dose and gradually increase it over several weeks. This dosing schedule helps to minimise the prevalence and severity of side effects. Dosing schedules must be managed by a medical professional.
In the worst cases, people receiving unsafe information in the UK have been hospitalised and required urgent medical care.
Counterfeit products
The demand and social media buzz for weight loss medications have created a situation in which counterfeit products are flooding the market. Some of these products may not be what’s advertised, could contain unsafe doses or may have harmful ingredients.
Lilly, the manufacturer of Mounjaro, says it has discovered counterfeit products, which contain bacteria, high levels of impurities, or even entirely different ingredients. In one case, it found a product that was actually just sugar alcohol – people may be spending hundreds, even thousands, on fake, dangerous products.
Why Mounjaro requires professional guidance
Mounjaro should be prescribed by qualified medical professionals, and you should be supervised when taking the medication. This ensures your progress is monitored safely and you have support managing side effects.
Long-term weight management isn’t just about medication—it’s about creating lasting lifestyle changes. The right support helps you build healthy eating and activity habits that make it easier to maintain your progress even after stopping treatment.
Oviva’s weight management support is built on sustainable nutrition strategies—focusing on what your body needs rather than banning foods or restricting entire food groups. Restrictive diets are difficult to maintain, but a balanced, nutrient-rich approach helps create long-term, healthy habits.
