Is Mounjaro Good for Weight Loss?

Yes, Mounjaro (tirzepatide) has shown impressive weight loss results in clinical trials. One of the key Mounjaro studies demonstrated that participants could lose up to 22.5% of their initial body weight over 72 weeks, at the highest maintenance dose.

For this reason, Mounjaro is considered one of the most effective weight loss medications available. To highlight this, let’s quickly take a look at how the treatment fares against one of its main competitors, Wegovy.

When comparing Mounjaro and Wegovy, Mounjaro can offer even greater weight loss results. Clinical trials show that tirzepatide users lost an average of 20.2% of their starting body weight, compared to 13.7% for semaglutide, over 72 weeks. Therefore, it is suggested that Mounjaro outperforms Wegovy. Both medications target appetite regulation, but Mounjaro works on two hormone pathways (GLP-1 and GIP), whereas Wegovy only targets GLP-1 receptors, which likely explains the different outcomes.

Mounjaro Injection Reviews: A Deep Dive

There’s a lot that goes into deciding whether to use Mounjaro for weight loss. You’ll need to consider how effective the treatment is, the potential side effects you may encounter, and how to use the injection pens. If you do end up deciding to purchase Mounjaro, it might also be a good idea to think about where you buy the medication from.

With this in mind, we’ve broken down our Mounjaro injection reviews into four main categories:

• Weight loss results
• Impact of side effects
• Reviews of the Mounjaro Kwikpen itself
• Customer opinions about the service they’ve received from Prescription Doctor

Taking all of this into consideration should help you make an informed decision about whether Mounjaro is right for you.

Mounjaro Side Effects Reviews

Side effects are possible with any medication, including Mounjaro. While many people tolerate it well, some do report mild issues, which tend to settle over time. Let's take a look at some UK-based reviews about Mounjaro side effects: 

“Keeps working, small loss most weeks. Side effects calm down over time, still get sick feeling, indigestion and leg cramps now and again. Overall, so far, 2.5 stone in 6 months.”

Barbra Davidson

“Only just had the second shot. It does take away the cravings. Don’t feel that hungry. First few days after the shot, I have felt nausea & slight headache, but it does wear off.”

Leigh Milward

“Amazing product, reduced my appetite, no side effects for me.”

Warren Brading

Most side effects of Mounjaro can be managed at home and usually subside relatively quickly. If you do find that you’re struggling to cope, our clinicians can discuss your options, which may include switching to an alternative weight loss medication. 

Mounjaro KwikPen Reviews

The Mounjaro KwikPen is a pre-filled, easy-to-use injection device which you will use to administer the medication yourself at home. People frequently comment on how convenient and simple it is to use: 

“Very easy to use, comes with step-by-step instructions. I found it works almost straight away, with only slight nausea on the first day. Like you only have to inject once a week.”

Karen Lovering

“Easy to use, so far great.”

Sandra Donnelly

“Does what it says, easy to use, good instructions.”

Lynn Cox

Each Mounjaro KwikPen contains four doses of tirzepatide, available in strengths of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, or 15 mg, depending on your dosage schedule. The pen delivers a precise amount of Mounjaro and requires no assembly, allowing you to inject it with ease on a weekly basis.
