Both work on the same basic idea, but they differ in how many targets they act on.
Semaglutide acts on one receptor — GLP-1. That is the hormone your gut releases after you eat.
Tirzepatide acts on two — GLP-1 and GIP. GIP is a second gut hormone involved in blood sugar and in how your body handles fat.
What that means in practice
• Both lower appetite and slow digestion.
• Both help steady blood sugar.
• Tirzepatide works on one extra pathway, which is part of why people respond differently to each one.
We would love to tell you which one is right for you. Honestly, nobody can predict that from the outside. Response varies a lot from person to person, and so do side effects which is why ongoing support is essential to your success.
If you start one and it is not working for you, switching is often an option.
