Setup, so nobody has to ask: dulaglutide · phosphate-buffered diluent.

This is a procedural question rather than a theoretical one, and I would like the procedure rather than the theory.

What I have done so far is read the label documentation where it exists and the two pharmacopoeial monographs that are publicly available, which cover the licensed presentation and say nothing about a research one.

What is the correct sequence, and where is the step that people usually skip?
