Does retatrutide adsorb measurably to the vial wall at 5 mg/mL?

Stated plainly: retatrutide · 5 mg/mL.

I have worked this out and I would like someone to find the error, because I suspect there is one.

My working so far, for the record, is below, and I am fairly sure the error is in the unit conversion rather than the algebra.

How many significant figures are actually justified here?

I would gently push back on the second point — the evidence there is thinner than stated. – otto_brenner 35 days ago
