Peptide Overviews
Tirzepatide
AFDA ApprovedTirzepatide is the first dual GIP and GLP-1 receptor agonist, approved by the FDA for type 2 diabetes (Mounjaro) and chronic weight management (Zepbound). Achieves unprecedented weight loss in clinical trials.
Survodutide
BHuman StudiesSurvodutide is a dual GLP-1 and glucagon receptor agonist developed by Boehringer Ingelheim. In Phase 3 trials, it demonstrates significant weight loss and is also being investigated for metabolic dysfunction-associated steatohepatitis (MASH/NAFLD).
