Is a 27G needle the right choice for drawing cagrilintide at 2.5 mg/mL?

Asked 29 Oct 2025Modified 9 months agoViewed 13k times

What I am working with: a 27G needle · cagrilintide · 2.5 mg/mL.

I suspect the honest answer is that it depends, in which case I would like to know on what.

Assume I can obtain either option without difficulty, so availability is not the deciding factor.

Is there a defensible reason to prefer one, or is this a coin flip?
