GLP-1 and GIP and considered to be incretin hormones. These are hormones that get released when you eat. Mounjaro tirzepatide mimics their effects. This signals the pancreas to relax insulin after eating and signals the liver to decrease the output of glucose. These help you feel satiated, slow down digestion, and lowers blood sugar levels.   Tirzepatide helps you lose weight in a few ways. It signals your brain and tells it you are full, so you eat less. It also slows how fast the food moves through your stomach, so you feel full longer.   It is often compared to similar types of drugs that only mimic GLP-1. Since tirzepatide impacts GLP-1 and GIP it produces better results for weight loss.   Mounjaro tirzepatide is injected under the skin like similar drugs of its kind. It can be done with a syringe or pen injector. You can easily do this at home without the need for a healthcare provider to be present. It is injected once a week into the fatty tissue beneath the surface of the skin. Your doctor will instruct you on the best way to do this and the best locations for injections.
