A one-page sheet for recording what is in a vial and every entry you make from it. Print it, or save it as a PDF. It is free, there is nothing to sign up for, and it works whether or not you use the app.
For research, informational and record-keeping reference only. The sheet is blank: it records what you have already decided with your healthcare provider.
A vial's concentration is the one number that everything else follows from, and the one nothing on the label tells you once the liquid is in.
One page, black and white, no colour ink needed. Use the print button, or save it as a PDF from the print dialog.
The top block is the vial: what the label said, the liquid you added, and the concentration that results. Every later number depends on those three.
Date, time, the amount, the syringe mark and the site. Twenty-four lines to a page, so one sheet covers a vial for most people.
One vial per sheet. Fill in the top block when you mix it, then add a line for each entry.

Printing tip: choose A4 or Letter, portrait, and turn off headers and footers for the cleanest result. In the print dialog you can pick “Save as PDF” instead of a printer.
We publish plain-English guides on reconstitution math, syringe units and keeping records, plus new calculators as they go up. Leave your email and we will send them over.
Paper works, and it never runs out of battery. But a sheet cannot count down what is left in a vial or remind you when the next entry is due. Peptrack keeps the same record, works out the concentration for you, and is free with no paid tier.
All four run in your browser, with no signup, and none of them suggests an amount.
