Mounjaro slimming syringe: active ingredient, dosage, application with videos

Mounjaro – The Mounjaro weight loss injection is one of the new beacons of hope in the field of medical support for weight loss. Mounjaro sets new standards with tirzepatide. It combines two mechanisms of action and shows impressive results in weight loss and diabetes management. The weekly injection makes Mounjaro an exciting innovation. Tip! Everyone knows Ozempic as a weight loss injection, but what else is there? Discover a comparison of weight loss injections 2025 here.

What is Mounjaro?

The active ingredient tirzepatide in Mounjaro acts on two important hormones that control appetite and blood sugar regulation.

Compared to other weight loss injections such as Ozempic, which only targets one hormone, Mounjaro offers “more effect for the same use”, so to speak.

2x to 3x more effective than Ozempic

Wow! Studies with over 18,000 participants have shown that Mounjaro is more than twice as effective when it comes to losing 10% of body weight. Some users even report losing over 100 pounds (i.e. 50 kilograms) in two years.

How does Mounjaro work?

The mode of action of Mounjaro comprises several levels:

• It reduces the feeling of hunger by reinforcing signals in the brain that make you feel full.
• It slows down digestion so that less food is absorbed.
• It stabilizes blood sugar and reduces insulin resistance.

The result? A noticeable reduction in appetite and a feeling of satisfaction after smaller meals – important building blocks for long-term weight loss.

Dosage and application

Mounjaro is injected once a week, which makes it particularly convenient. The dosage typically starts at 2.5 mg per week and can be increased up to 15 mg depending on tolerance and need. The injections are easy to administer and come with a pre-filled pen that does not require additional needles.

A big advantage: you can integrate the application flexibly into your everyday life, as the time of the injection does not matter – in the morning, in the evening or whenever it suits you.

Effects on weight

The impressive effects of Mounjaro on weight are based on clinical studies and real experiences. Many users report a significant weight reduction within a few months. On average, users lose around 15-20% of their body weight over the course of a year.

However, Mounjaro is not a magic solution: as soon as the treatment is discontinued, the weight often returns. The medication therefore only works for as long as it is used. A change to a healthy diet and more exercise is essential to maintain the results in the long term.

Mounjaro vs. other weight loss injections

Compared to other injections such as Ozempic, Wegovy, Saxenda, Rybelsus, Trulicity or Victoza, Mounjaro offers clear advantages thanks to its dual hormone effect:

• Greater effectiveness in weight reduction
• Lower dosing frequency (once a week)
• Fewer fluctuations in blood sugar

However, Mounjaro is not suitable for everyone. It is currently only approved for the treatment of type 2 diabetes, although many doctors prescribe it off-label for weight loss.

What does Mounjaro cost?

Unfortunately, Mounjaro is not cheap. The costs can amount to several hundred euros per month, especially if it is used off-label. Many insurance companies only cover the costs if it is used to treat diabetes. For pure weight reduction, most patients have to bear the costs themselves.

Possible side effects

Rarely, but always important to mention, like all medications, Mounjaro has potential side effects that you should be aware of:

• Nausea and vomiting, especially at the start of treatment
• Digestive problems such as diarrhea or constipation
• Rarer side effects such as pancreatitis

Experts advise that treatment should only be started under medical supervision and that attention should be paid to possible symptoms.

Conclusion: Is Mounjaro right for you?

Mounjaro offers a promising way to lose weight, especially for people with type 2 diabetes. Thanks to its dual hormone action, it is more effective than many other weight loss injections. However, the cost and possible side effects must be taken into account.
