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.
AOD-9604
CPreclinicalAOD-9604 is a modified fragment of human growth hormone (amino acids 176-191) originally developed for obesity treatment. It has been explored as a lipolytic agent in research but has not received FDA approval or GRAS status for any use.
