Is a 25G drawing needle the right choice for drawing a GLP-1 receptor agonist at 10 mg/mL?

Asked 6 Oct 2024Modified 22 months agoViewed 13k times

What I am working with: a 25G drawing needle · a GLP-1 receptor agonist · 10 mg/mL.

Both of these get recommended confidently by different people, which suggests neither is obviously right.

My constraints are cost, measurement resolution and how much handling I am prepared to do — in roughly that order.

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