Semaglutide and Tirzepatide injections are very similar except:

Semaglutide injections MIMICK a hormone called glucagon-like peptide-1 (GLP-1) that the body naturally produces while Tirzepatide injections TARGET GLP-1 and the GIP receptor agonist.

GLP-1 is released in the gut after eating and prompts the body to produce more insulin (which lowers blood sugar). Semaglutide connects with GLP-1 receptors in the brain that regulate appetite and how much a person eats. It may also slow down digestion which makes a person feel full for a longer period of time.
