Printable GLP-1 tracker: a 12-week injection log

What each column is for

Six columns, and each one earns its place. Week is just the row label, so the sheet stays readable when a date slips. Date is the column worth filling first: writing down the day the injection actually happened, not the day it was planned for, is what turns a stack of shots into a schedule you can see. If a step-up plan is already set, the titration date planner gives the earliest date each step can begin, and those dates can go into the sheet in pencil ahead of time.

Dose (mg) holds what was actually injected, in milligrams rather than pen clicks or units, so the number still means something a year from now. Injection site is the column people skip and then regret, because rotation only works if you can see where the last few shots went — the injection sites guide covers the standard areas and how far to move each week. Weight shares the row with the dose so the two can be read side by side — worth stepping on the scale the same way each week, ideally on the same morning.

Notes is deliberately narrow: one line, because a column you dread filling is a column you stop filling. Those five data columns are not arbitrary — they are the short list that a prescriber actually asks about at a follow-up, and what to track on GLP-1 explains why the list stays short and what quietly falls off it.

Paper, app, or spreadsheet

Paper wins on the things nobody thinks about until they break. It survives a new phone, a dead battery, and a cancelled subscription. It needs no account, no permissions, and no network, and it can be handed across a desk at an appointment without unlocking anything. What it cannot do is equally plain: paper never reminds you, never counts a date, never adds anything up, and it stays home in the drawer on the day you inject at a friend's place.

A spreadsheet sits in between. It does arithmetic, sorts, and charts, and it syncs across devices — but typing into one on a phone with a pen in your other hand is a chore, and a spreadsheet has never once nudged anybody on shot day. Reminders are the whole gap between a record and a routine, which is what the GLP-1 shot tracker app is built around: a notification on injection day, the next rotation site suggested rather than remembered, and weight arriving from Apple Health instead of being retyped.

There is no correct answer here, only an honest one: the log you will actually fill in beats the one with better features. Plenty of people run both — paper on the fridge for the household, the app for the reminder. If the calendar math is the part that keeps slipping, the free tools on this site handle dates and dose arithmetic in the browser, with nothing to install.
