What a mass spectrometer does to a peptide before it measures anything
The ionisation method determines the charge states you see, the adducts you must account for, and the modifications you might destroy in the process.
Target dose, effective dose, and the distance between them

Two analysts, one chromatogram, two answers
We work through a single chromatogram twice, under two integration conventions, and show where the difference comes from.
The lowest effective dose is a real concept with almost no data behind it
Every withdrawal trial compared full dose against nothing. The clinically interesting comparison — full dose against a reduced one — has not been randomised.
How a claim degrades between the bench and the listing
Every step between the laboratory report and the product page removes information, and the badge is the last step.

Real-world persistence figures, with their definitions stated, because the definitions are doing most of the work.
The incidence tables, read line by line
Trial adverse-event tables count episodes reported to a study nurse. They are the best data we have and they systematically under-record the mundane.
