Mounjaro Kwikepin (Tirezaptide) is the newest injectable prescription medication which can be used for weight loss and diabetes management. It works by reducing appetite, making one feel full longer and also regulating blood sugar levels.
You can now order weight loss injections Mounjaro online from Meds For Less easily, conveniently and reliably to your home address for next day delivery.
Mounjaro KwikPen (tirzepatide) is an injectable prescriptiom medication used for weight loss and diabetes control. It works by mimicking two hormones in the body, GLP-1 and GIP and has the mechanisms of better blood sugar control and better appetite control (by making you feel full for longer).
Mounjaro injection can be taken once a week in the abdomen, thigh or upper arm.
The dosage will be tailored to your individual sugar control/weight loss need and can be decided between yourself and your healthcare provider. Usually Mounjaro doses are started low and then increased gradually to help the body tolerate the effects.
The Mounjaro medication contains the active ingredient Tirzepatide and belongs to a new class of drugs which mimic both GLP-1 and GIP hormones in the body.
Mimicking these hormones blood sugar regulation and weight loss occurs in the following ways:
Mounjaro is unique in it’s dual action, containing both GIP and GLP-1 mimetic. In contrast to previous GLP-1 only mimetics, Mounjaro has an enhanced action profile when it comes to weight loss and blood sugar control.
Mounjaro is recommended for patients with obesity (Having a BMI > 30) or for Overweight patients (BMI > 27) who have weight related health concerns such as type 2 diabetes, hypertension or high cholesterol.
Mounjaro has shown a high level of effectiveness with blood sugar control in the management of type 2 diabetes and weight loss potential in obesity.
Clinical trials have shown that Mounjaro can reduce HbA1c levels (a marker for diabetes) from 2.1% to 2.4% over the period of 9 months to a year. Over 90% of people who used Mounjaro achieved a reduction of Hba1c down to 7%, (the typical target for diabetes management). This was shown to be more than that achieved by other treatments such as Ozempic or Insulin.
Clinical trials have also shown that Mounjaro is very effective for weight loss. Mounjaro weight loss has shown to be more effective than previous weight loss medications such as Wegovy, achieving up to 22.5% weight loss over 72 weeks when combined with diet restrictions and exercise.
This high degree of effectiveness of the Mounjaro injection for weight loss can be attributed to it’s dual action as both a GLP-1 and a GIP mimetic and has been described as a “game changer “ for obesity and diabetes management.
Mounjaro can be administered via a subcutaneous injection once a week. Dosages are started low and increased gradually over time to help the body get used to the effects of the medicine.
Mounjaro is initially started at a dose 2.5 mg once weekly for the first 4 weeks and then gradually to a maintenance dose of 5mg once weekly. If additional dosage is required, the dose may be increased further to:

Using Mounjaro medication effectively means monitoring weight, blood sugar levels, and overall well-being. Patients can track changes weekly to see how the Mounjaro injection for weight loss or diabetes medication Mounjaro impacts their goals. Regular check-ins with healthcare providers also ensure that the right dose is maintained and that potential side effects are addressed early.

Yes. Mounjaro can be prescribed to people without diabetes if they are clinically obese (BMI ≥30) or overweight (BMI ≥27) with weight-related health issues like high blood pressure or sleep apnoea. You cannot use it just for “cosmetic weight loss” — a doctor must assess if it is medically necessary.
No, Mounjaro is not available over the counter. It is a prescription-only medication, meaning a pharmacist or online clinic must review your medical history before supplying it. Buying it without a prescription is unsafe and illegal in the UK.
The price of Mounjaro typically starts from £159.99 per pen, depending on the dose. Each pen contains four doses and lasts one month. Higher strength pens cost more, and insurance or NHS coverage is currently limited.
Each Mounjaro KwikPen contains four pre-set doses that are used once a week. This means one pen lasts for 28 days. After this, you will need a new pen if treatment continues.
Yes — but only from licensed UK online pharmacies that provide a prescription after a medical assessment. Make sure the website displays a GPhC (General Pharmaceutical Council) or MHRA registration. Avoid websites selling it without a prescription, as those may supply counterfeit or unsafe products.
No. Mounjaro should not be used during pregnancy, as there is not enough evidence to confirm it is safe for the baby. Women should stop Mounjaro at least 1–2 months before trying to conceive and speak to their doctor if they become pregnant while using it.
It is not recommended. It is unknown whether tirzepatide, the active ingredient in Mounjaro, passes into breast milk. To avoid any risk to the baby, your doctor will usually suggest stopping Mounjaro or delaying treatment until after breastfeeding.
Most side effects are mild and temporary, such as nausea, diarrhoea or reduced appetite, especially when beginning treatment. However, in rare cases, users may experience pancreatitis, gallbladder problems or changes in vision. Long-term safety data is still being collected, so regular check-ups with a healthcare provider are recommended during extended use.
Mounjaro is only licensed for adults aged 18 and over. It is not currently approved for use in children or teenagers. Anyone under 18 should not use Mounjaro unless specifically advised by a specialist doctor.
Yes. Each pen has an expiry date printed on the label and packaging, and should not be used after this date. Using expired Mounjaro may reduce its effectiveness or cause irritation. Always check the date before injecting.
Before first use, Mounjaro should be stored in the refrigerator (between 2°C and 8°C). After opening, the pen can be kept at room temperature (up to 30°C) for a maximum of 30 days. Do not freeze it or expose it to direct sunlight or heat.
Moderate alcohol consumption is generally safe, but both alcohol and Mounjaro can affect blood sugar levels, especially in people with diabetes. Alcohol may also worsen nausea or digestive side effects caused by Mounjaro. It’s best to limit alcohol and speak to your doctor if you are unsure.
