THE BASICS
Semaglutide
Semaglutide is a GLP-1 (glucagon-like peptide-1) receptor agonist. It mimics a natural hormone that regulates appetite and blood sugar. Originally developed for type 2 diabetes, it's now widely used for weight loss. Works by reducing hunger and slowing stomach emptying.
Tirzepatide
Tirzepatide is a dual GIP/GLP-1 receptor agonist. It activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors. The dual mechanism produces stronger weight loss than semaglutide alone. Works systemically for appetite, metabolism, and insulin sensitivity.

FAQ
Which one is better for weight loss?
Tirzepatide produces 20-30% more weight loss than semaglutide on average. If maximum weight loss is your goal and you can tolerate slightly more side effects, tirzepatide is superior. Semaglutide is better if you want proven long-term safety and slightly gentler side effects.
