Quick answer

MounjaSlim: what to know first

MounjaSlim is Hori Clinic's physician-supervised tirzepatide weight-management programme. It is not a quick slimming injection: eligibility, the exact medicine, contraindications, dose escalation, nutrition and follow-up must be confirmed for each person.

Suitable for: Adults with obesity, or overweight with a related health condition, after medical eligibility assessment
Discuss first: Discuss pregnancy plans, personal or family thyroid-cancer history, MEN2, severe gastrointestinal disease, pancreatitis or gallbladder history, kidney risk and all medicines
Discomfort: A brief injection prick; nausea, fullness, constipation or diarrhoea may be more relevant than injection pain
Downtime: No procedural downtime, but gastrointestinal symptoms and dehydration can affect daily activity
When change may be noticed: Appetite effects may begin after starting treatment; weight change is gradual and assessed over months
Alternatives: Nutrition, physical activity, behavioural care, another approved medicine or bariatric referral

What is Mounjaslim?

Mounjaslim is a doctor-supervised weight-management programme built around tirzepatide, a once-weekly injectable. Tirzepatide is a dual agonist — it activates both the GLP-1 and GIP receptors, the gut-hormone pathways that signal fullness and help regulate blood sugar and how the body handles food.

In practice this reduces appetite and cravings and slows stomach emptying, so it is easier to eat less without constant hunger. It is started at a low dose and titrated up under medical supervision, alongside nutrition and lifestyle guidance — never a substitute for them. A doctor screens suitability and monitors for side effects.

How it works

Tirzepatide mimics the GLP-1 and GIP hormones that signal fullness.

Appetite and cravings reduce, and the stomach empties more slowly.

Used alongside diet and lifestyle guidance under medical supervision.

On the day and afterwards

After a medical assessment to confirm suitability, tirzepatide is given as a once-weekly injection, usually started at a low dose and titrated up under supervision. The clinic guides you on technique, diet and managing any side effects.

Mild nausea or digestive changes can occur early and usually ease as the body adjusts and the dose is titrated. Ongoing medical follow-up monitors progress and safety.

When changes may appear

Weight loss is gradual over weeks to months and works best combined with dietary and lifestyle guidance. It is a medical programme — results and suitability are determined by your doctor.

Everyone responds differently. Before treatment, your doctor will examine the area and talk through a plan that makes sense for you.
