Is a 30G needle the right choice for drawing tirzepatide at 2.5 mg/mL?

Asked 5 May 2024Modified 2.2 years agoViewed 9k times

Concretely: a 30G needle · tirzepatide · 2.5 mg/mL.

These are treated as interchangeable and I do not think they are.

If both are acceptable I would like to know that, so I can stop thinking about it.
