Can I reconstitute dulaglutide at 20 mg/mL and still measure a small dose accurately?

What I am working with: dulaglutide · 20 mg/mL.

I would like to set this up properly once, rather than adjust it repeatedly.

My budget is real but not tight, and my tolerance for uncertainty is low.

What would you do, and what would make you change course?
