APX-3

APX-3 is Apex’s catalog name for a single-peptide research compound that engages GLP-1, GIP, and glucagon signaling—an approach sometimes informally described as “GLP-3.”

Search terminology: APX-3 is Apex’s catalog name for a triple-receptor research compound. It may also appear in searches as “GLP-3,” “RETA,” or “retatrutide.” “GLP-3” is an informal nickname, not an official scientific classification.

What researchers study

APX-3 in context

All three targets are class B G-protein-coupled receptors. APX-3 binding activates Gs-protein signaling, raises intracellular cyclic AMP, and produces different downstream effects depending on the receptor and tissue involved.
