A one-page dose card for the fridge door

Most of what you need at the moment of injection fits on one small card, and having it physically next to the vial removes the step where you unlock a phone with cold hands and go looking for a number.

The card holds four things. The concentration of the current vial in milligrams per millilitre. The current dose in milligrams. The resulting volume in millilitres and, if you use an insulin syringe, the same figure in units. That is it.

The reason to precompute the volume rather than the dose alone is that arithmetic done in a hurry is arithmetic done badly. The calculation should happen once, calmly, when you mix the vial, and be read off thereafter.

Add the mixing date and the discard date to the same card and it doubles as the vial's own record. Add the lot number and it covers everything you would want if there were ever a question about that specific vial.

The card is not the log. It describes the present state only, gets thrown away with the vial, and is replaced with a new one at the next mix. The history lives in a Peptide Tracker & Calculator where it can accumulate. Trying to make one artefact do both jobs produces something that does neither well.

Write it by hand. Handwriting the numbers is a final check on them, and a card you copied without reading has skipped the only real safety step in the process.
