What Efinopegdutide is
Beat semaglutide on liver fat in a randomised head to head, cutting it 72.7 percent against 42.3 percent, while the weight difference was not significant. Adding glucagon does something to the liver that GLP-1 alone does not.
Most dual agonists on this site pair GLP-1 with GIP. This one pairs it with glucagon, which sounds wrong to anyone who knows glucagon raises blood sugar, and the logic is worth following.
Mechanism: A co-agonist at the GLP-1 and glucagon receptors, built on a long-acting Fc-based scaffold. GLP-1 receptor agonism reduces food intake and improves glycaemic control in the usual way.
Regulatory history: Investigational. Not approved. Licensed to Merck, originally from Hanmi, and previously carried Johnson and Johnson and Hanmi identifiers.
How TGA treats this kind of product
Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.
The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Efinopegdutide 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.
