Read the methods section. It is the only part that says whether the conclusion is allowed to exist.

Take one to a pharmacist. Free, two minutes, correct. Everything else here is a hypothesis.

Cold storage, light protection, date on the vial. Boring, removes half the variables.

Did not know half of this. Thanks.

Baseline first.

Narrow conclusion.

I would stop trying to convey how bad it is and start saying what you want them to do.

Same shape here, different drug. The thing that helped was documenting the refusal rather than re-arguing it. They refer rather than write.
