How much of the gross mass of a 30 mg orforglipron vial is actually peptide?

What I have: 30 mg · orforglipron.

I can do the algebra. I am not confident about the conversion factors.

If there is a standard way to lay this out, I would rather learn that than invent one.

Can someone show the working rather than just the answer?

Good answer, but the confidence interval in the cited trial is wider than implied. – b_delacroix 42 days ago
