Is there any published stability data for dulaglutide at 2–8 °C?

Asked 22 Jun 2026Modified 38 days agoViewed 1.9k times

What I am working with: dulaglutide · 2–8 °C.

This is asserted often enough that I assumed it was established, and then I went looking for the source.

I have searched the primary literature and found one paper that is adjacent but not on point.

Has anyone verified this independently?
