How They Compare
Wegovy and Compounded Tirzepatide represent two distinct approaches to GLP-1 based weight management. Wegovy contains semaglutide, a GLP-1 receptor agonist, while Compounded Tirzepatide contains tirzepatide, a dual GIP/GLP-1 receptor agonist. The dual mechanism of tirzepatide targets two incretin pathways simultaneously, which clinical trials suggest may produce greater average weight loss. However, both medications have proven effective, and the best choice depends on individual factors including insurance coverage, side effect tolerance, and provider availability.
