What HEC88473 is
The only GLP-1 pairing on this site that is not with another incretin. Combining GLP-1 with FGF21 targets appetite and liver metabolism through genuinely separate pathways.
Almost every dual agonist documented here pairs GLP-1 with GIP, glucagon or amylin, all of which are gut or pancreatic hormones acting on related receptors. This one pairs it with FGF21, which is a different kind of signal entirely.
Mechanism: A single molecule with agonist activity at both the GLP-1 receptor and the FGF21 receptor complex. GLP-1 receptor agonism reduces food intake and improves glycaemic control conventionally.
Regulatory history: Investigational. First-in-human only. Not approved anywhere.
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for HEC88473 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
