Is a 31G needle the right choice for drawing dulaglutide at 5 mg/mL?

Asked 28 Oct 2025Modified 9 months agoViewed 8.4k times

What I have: a 31G needle · dulaglutide · 5 mg/mL.

I want to know what the trade-off actually is rather than which option is fashionable.

I would rather have a defensible reason than a marginal improvement.

What does each option buy me, and what does it cost me?
