With so many new weight loss treatments becoming available, many patients are asking the same important question: What is the best injection for weight loss? The answer isn’t always straightforward. It depends on your health, lifestyle, goals, and how your body responds to treatment.
At CarePoint Pharmacy, we offer private consultations to help you find the most effective, safe, and sustainable solution. In this guide, we’ll walk you through the questions you should be asking yourself before choosing between Mounjaro, Wegovy, and Saxenda, three of the leading weight loss injections in the UK.
Q: How much weight do I want or need to lose?
Your target weight loss can help determine which treatment might be most appropriate. All three injections (Mounjaro, Wegovy and Saxenda) have been clinically proven to help with weight loss, but the amount of weight lost differs slightly between them.
-
Mounjaro tends to produce the most significant weight loss, with some patients losing up to 20% of their body weight over several months
-
Wegovy often results in weight loss of up to 15%
-
Saxenda is slightly less powerful, typically resulting in up to 5–10% body weight reduction
If you’re looking to achieve a larger weight loss goal, Mounjaro or Wegovy may offer more impact.
Q: How quickly do I want to see results?
Everyone’s body responds at a different pace, but if you’re hoping for steady progress within a few weeks, you’ll want to consider how each injection works.
-
Mounjaro and Wegovy are both once-weekly injections, making them easy to maintain. Many patients report reduced appetite within the first 1–2 weeks
-
Saxenda is a daily injection, which may be more difficult for some patients to keep up with, but it can also provide earlier feedback on how your body is responding
For convenience and quick results, the weekly treatments may be a better fit.
Q: Do I have any underlying health conditions?
Your medical history plays an important role in determining the safest and most effective treatment. For example:
-
Mounjaro is often chosen for patients who are living with type 2 diabetes, as it helps regulate blood sugar in addition to supporting weight loss
-
Wegovy is suitable for patients without diabetes but with a high BMI or weight-related health risks such as high blood pressure or cholesterol
-
Saxenda may be appropriate for patients who have tried other methods first but need extra help with appetite control

Q: How good am I at sticking to routines?
The best injection for weight loss is one you’ll actually remember to use. If you’re someone who struggles with daily routines, then a once-weekly treatment might work better for you.
-
Mounjaro and Wegovy are taken once a week
-
Saxenda requires a daily injection and gradual dose increase over time
If you travel often or have a busy schedule, the simplicity of a weekly dose can be a game-changer.
Q: Am I ready to change my lifestyle too?
Weight loss injections are not magic fixes. They’re tools to help reduce hunger, improve portion control, and support habit change. But they work best when combined with:
-
A nutritious, balanced diet
-
Regular physical activity
-
Ongoing lifestyle coaching and support
At CarePoint Pharmacy, we combine medical treatment with the guidance of our in-house nutritionist to give you the best chance of long-term success. If you’re ready to embrace those changes, you’re far more likely to see the results you want—no matter which injection you choose.
Q: Do I want regular support along the way?
Some patients prefer a bit more hands-on support, while others are confident managing their plan once they get started. Either way, we offer regular check-ins, dose reviews, and lifestyle coaching for all of our patients using weight loss injections.
This added guidance can be especially helpful in the early stages, when adjusting to appetite changes or navigating side effects.
What Does Each Injection Do?
Let’s summarise what we’ve covered:
Mounjaro is a weekly injection that works on two hunger-regulating hormones (GLP-1 and GIP). It tends to lead to the greatest weight loss and is especially helpful for patients with type 2 diabetes or significant obesity.
Wegovy is also a weekly injection, targeting GLP-1 only, and is ideal for patients without diabetes who are overweight or obese. It offers impressive results, especially when paired with lifestyle support.
Saxenda is a daily injection, slightly less powerful but still very effective for reducing appetite and promoting gradual, consistent weight loss—particularly for those starting at a lower BMI or preferring a familiar option with a longer track record.
