SerenQ Retatrutide is a pre-filled research pen containing retatrutide, an investigational peptide designed to activate three metabolic hormone receptors: GIP, GLP-1 and glucagon receptors.
This triple-receptor activity is what distinguishes retatrutide from earlier compounds in the same research area. GLP-1 and GIP signalling are closely involved in glucose regulation, insulin response and appetite signalling, while glucagon receptor activity adds another pathway linked with energy use and metabolism.
Retatrutide is a long-acting peptide engineered to remain in circulation for longer than naturally occurring metabolic hormones. Current clinical research is investigating its effects across body weight, glucose control, metabolic health and obesity-related complications. Retatrutide remains in Phase 3 clinical development and has not been approved as a medicine.
Every SerenQ pen carries a unique serial number and QR code. The QR system allows the product and batch information to be checked independently before opening the carton.

Retatrutide remains an investigational compound. Although multiple Phase 3 studies have now reported results, it is not currently an FDA-approved medicine, and Lilly states that availability depends on completion of the clinical development and regulatory approval process. SerenQ Retatrutide is not an approved Lilly medicinal product.
