So, Are These Injections Actually Done At Home?
Yes. Both Wegovy (semaglutide) and Mounjaro (tirzepatide) come in pre-filled auto-injection pens that are designed for self-administration. You inject once weekly into the fatty tissue of your abdomen, thigh or upper arm. Most patients find the process straightforward after their first use, and full guidance is provided as part of your treatment pathway.
How Do The Two Medications Actually Work?
This is where the two differ in a clinically meaningful way.
Wegovy works by mimicking GLP-1, a hormone that regulates appetite and slows gastric emptying. It signals to your brain that you are full, helping reduce overall calorie intake.
Mounjaro works on two hormones simultaneously: GLP-1 and GIP. This dual action not only reduces appetite but also appears to influence how your body processes and stores fat. It is this dual mechanism that has drawn significant attention in clinical research.
According to a study published in The Lancet, tirzepatide (Mounjaro) produced mean weight reductions of up to 22.5% of body weight at the highest dose over 72 weeks, making it one of the most effective pharmacological weight loss treatments studied to date.
Does That Mean Mounjaro Is Better?
Not necessarily. Clinical trial results reflect averages across large populations. Individual responses vary considerably depending on your metabolism, starting weight, lifestyle habits and how well you tolerate each medication. Some patients achieve excellent, consistent results on Wegovy. Others find that the dual action of Mounjaro suits them better. The only way to know which is right for you is through a proper clinical assessment.
What About Side Effects At Home?
Both medications share a similar side effect profile, particularly in the early weeks. Common effects include:
-
Nausea, particularly after dose increases
-
Digestive discomfort or changes in bowel habits
-
Reduced appetite, which is also the intended effect
-
Mild fatigue during the adjustment period
The good news is that most side effects are temporary and manageable. Having clinical support means you are never navigating these alone. A quick conversation with your prescriber can often resolve concerns before they lead to stopping treatment unnecessarily.
How Much Do They Cost In 2026?
Both discounts can be discussed when you contact us or at the point of booking. Pricing may vary depending on dose and duration of treatment.
Is A Cheaper Online Option Just As Good?
This is an important question. There are unregulated online sources advertising weight loss injections at lower prices, but these carry real risks. Medications sourced outside of regulated UK supply chains cannot be guaranteed to be genuine, stored correctly or dispensed at an appropriate dose. Beyond the medication itself, there is no clinical oversight, no side effect management and no one to call if something goes wrong.
When comparing weight loss injections, the cost of proper clinical care is not an optional extra. It is the part that makes the treatment safe and effective.
What Does A Dose Escalation Schedule Look Like?
It is important that dose increases are never rushed. Gradual escalation reduces the intensity of side effects and allows your body to adjust properly.
Who Is Eligible To Use These At Home In The UK?
Eligibility is based on clinical criteria regardless of whether you access treatment privately or through the NHS. You are likely to be considered suitable if:
-
Your BMI is 30 or above
-
Your BMI is 27 or above alongside a weight-related condition such as type 2 diabetes or high blood pressure
-
You are aged 18 or over
-
You are not currently pregnant or breastfeeding
-
The medication does not interact with your current prescriptions

Once we have a clear picture of your health profile, we discuss whether Wegovy or Mounjaro is the more appropriate option for you. This decision is guided by clinical factors, not personal preference alone.
Your prescription is issued through a regulated UK supply chain. We walk you through how to self-administer safely at home, including injection site rotation, storage guidance and what to do if you miss a dose.
We monitor your progress through each dose stage, providing support with any side effects and adjusting your plan where necessary. You are never left to manage this alone between appointments.
Medication works best alongside changes to eating habits and daily activity. We provide practical guidance on nutrition and lifestyle to help you build sustainable habits rather than relying on the medication alone indefinitely.

So Which Is Actually The Best For Home Use?
The honest answer is that both are excellent options when accessed properly. The best injection for weight loss at home in the UK is the one that is clinically appropriate for your individual health profile, prescribed responsibly and supported with ongoing clinical care. For some patients that will be Wegovy; for others, Mounjaro will be the better fit.
What matters most is not which medication you choose, but how you access it and the level of support surrounding your treatment.
