## FAQ

### What is ecnoglutide (XW003) and how does it work?

Ecnoglutide (XW003) is a long-acting, lipidated GLP-1 receptor agonist from Sciwind Biosciences, built from natural amino acids. Fatty-acid conjugation extends its half-life; it activates the GLP-1 receptor with a cAMP-biased signaling profile.

### Is ecnoglutide FDA-approved in the United States?

No. Ecnoglutide is investigational and not FDA-approved in the U.S. It has received NMPA marketing approval in China for weight management, but that foreign-market status does not apply to or predict any FDA regulatory action.

### Is ecnoglutide prohibited in sport under WADA rules?

Ecnoglutide is not specifically named on the WADA Prohibited List. GLP-1 receptor agonists as a class appear on WADA's Monitoring Program—tracked in testing but not currently sanctioned—while the class remains under ongoing review.
