01 / What is it?
What is it?
Tirzepatide is a once-weekly medicine that acts like two natural gut hormones called GIP and GLP-1. These hormones help control blood sugar, hunger and the way the body responds to food.

Tirzepatide
Why do people find it interesting?
Studies show that tirzepatide can reduce hunger and help with substantial weight loss for some people. In the EU it is authorized for people with type 2 diabetes and, under specific conditions, for weight management.
What might you notice?
Many people feel less hungry, become full more quickly and stay full for a longer time. Nausea and stomach or bowel problems can be common, especially when treatment starts or the dose changes. These can include diarrhoea, constipation or stomach pain.
What happens in your body?
Tirzepatide activates GIP and GLP-1 receptors. It helps the body release insulin when blood sugar is high, slows digestion and sends fullness signals to the brain. Retatrutide is different because it also acts on the glucagon receptor. These substances should not be treated as interchangeable.
How long does it work?
Tirzepatide is designed for once-weekly use. If treatment is stopped, its effects on appetite and blood sugar gradually reduce. Weight may increase again if other long-term changes do not support weight management.
Keep the context
Important to know
Tirzepatide and Retatrutide sound similar, but they are not the same substance. You should not treat them as if they are the same, and you should not take extra injections to “catch up” a missed dose. Please leave enough time between injections, do not inject two doses close together, and keep a fixed weekly injection day whenever possible.

Dose information from the guide
Tirzepatide is dosed once weekly. The dose starts low to let the gut adjust, then steps up every 4 weeks. Each step is a 2.5 mg increment. The minimum-effective dose for weight loss or glycemic control is 5 mg. The maximum studied and approved dose is 15 mg. The 2.5 mg, 7.5 mg, and 12.5 mg doses are transitional steps, not long-term targets.
Look beyond the name
