How to Log Your First GLP-1 Dose
To log your first GLP-1 dose, write down four things at the moment you take it: the date, the dose exactly as your prescriber wrote it, the site you used, and one line about how you felt. Do that once and every later entry has something to compare against. It takes under five minutes.

The short answer
To log your first GLP-1 dose, write down four things at the moment you take it: the date, the dose copied exactly from the pharmacy label rather than from memory, the injection site, and one line about how you felt. Pick one place for the log and keep everything there. It takes under five minutes and becomes the baseline every later entry is read against.
Key takeaways
- Your first entry is the baseline every later entry is read against, so it is worth five careful minutes rather than a quick note you will not be able to interpret in eight weeks.
- Record four things: the date, the dose exactly as written on your prescription, the injection site, and a single line about how you felt that day.
- Copy the dose from the label rather than from memory. A dose written down slightly wrong on day one quietly corrupts every comparison you make later.
- Choose one place for the log and never keep a second one. Two half-complete records are worse than one imperfect record.
- GLP-1 Tracker keeps all four fields in a single entry on iPhone, but a paper notebook with the same four columns works, and this guide is written so either will do.
Four fields, not forty
Date, dose, site, and one line on how you felt. A log you can complete in a minute is a log you will still be keeping in month four; an elaborate one usually is not.
Copy, do not remember
Read the dose off the pharmacy label or your prescriber's written instructions and copy it exactly, including the units. Memory is the single most common source of a wrong record.
One home for the record
App, notebook, or spreadsheet — pick one and put everything there. Split records are the reason people arrive at an appointment unable to answer simple questions.
Set the next reminder now
The best moment to schedule the next dose reminder is the moment you finish logging this one, while the app or the notebook is already open in front of you.
Why the first entry is the one that matters most
Almost nothing you record on day one is interesting on day one. The date is obvious, the dose is fresh in your mind, and you have no trend to look at yet. That is exactly why people skip it.
The value arrives later. In week nine, when you are trying to work out whether a rough Tuesday is normal for you or new, the only thing that can answer the question is a record that goes back far enough and is consistent enough to compare against. A log that starts in week six has no week one to compare to.
So treat the first entry as the setup step it really is. You are not recording data; you are deciding what shape your record will have for the next year, and doing that carefully once is much easier than reconstructing it later.
GLP-1 Tracker visualizes your estimated medication level over time.
Write down what your prescriber actually prescribed
Before you record anything about the dose you took, write down the instruction itself: the medication name, the strength, and the schedule your prescriber gave you, copied word for word from the pharmacy label or the written instructions you were sent home with.
This is a separate line from your dose log, and it is worth keeping visible. It is the reference you will check against every week, and it is the thing you will want in front of you when a pharmacist or a nurse asks what you are on. Copy it; do not paraphrase it, and do not write it from memory the following morning.
Pick the one place your log will live
Decide now whether your record lives in an app, a notebook, or a spreadsheet, and then put everything there. This sounds trivial and it is the step people most often get wrong: they start in the phone's notes app, add a habit tracker a fortnight later, and end up with two partial histories that cannot be merged.
The right choice is whichever one you will actually open on a bad week. If that is paper, use paper. GLP-1 Tracker exists because a phone is usually the thing already in your hand when you take a dose, and because it keeps the dose, the site, the weight and the meal log in one timeline rather than four — but the discipline matters more than the tool.
Record the date and time you took it
Write the calendar date and the rough time of day. Not "this morning" — the actual date, because in six weeks "this morning" means nothing.
Time of day matters more than people expect. If you later want to describe a pattern to your care team, being able to say "I take it on Sunday evenings" is far more useful than "weekly". It also makes the gap between doses countable, which is the number most tracking views are built on.
If you are logging a dose you took earlier — yesterday, or last week — record the date it actually happened rather than the date you are writing it down. In GLP-1 Tracker the field is labelled "Taken at", and it will not accept a date in the future: you can backdate freely, but you cannot log a dose you have not taken yet. An accurate late entry is worth much more than a tidy wrong one.
Record the dose exactly as it is written on the label
Copy the strength and the units precisely as they appear on your prescription. Do not round it, do not convert it into a different unit, and do not write down what you think it should be.
This is the one field where a small error does real damage. A dose recorded slightly wrong on day one becomes the thing every later entry is compared against, and neither you nor your prescriber will spot the mistake — you will just quietly draw the wrong conclusion from your own history.
If your medication is prescribed in a form where the label and the device describe the dose differently, write down what the label says and raise the discrepancy with your pharmacist rather than deciding which one is right.
Note the injection site you used
If your medication is injected, record which site you used, using whatever names you are going to keep using. "Left abdomen" is fine. "The usual spot" is not, because in a month there will be three usual spots.
The reason to log the site from the very first dose is that site rotation is only visible in hindsight. You cannot look at a single entry and tell whether you are favouring one area; you can look at eight entries and see it immediately. Starting the record on dose one means that pattern is available when you first go looking for it.
Which sites are appropriate for your medication, and how to use the device, come from your medication's own instructions and from your prescriber or pharmacist — not from a tracking app.
Add a one-line note about how the day felt
One sentence, written the same day. Not a diary entry — a line you can scan later. "Tired by mid-afternoon, appetite low, no nausea" is exactly the right level of detail.
Write it even when the answer is "fine". A run of ordinary days is what makes an unusual one visible, and if you only write notes when something is wrong, your record will look far worse than your experience actually was.
This note is for your own reference and for the conversations you choose to have about it. It is not a symptom assessment, and no log can tell you whether what you are feeling needs attention. If something worries you at any point, contact your provider rather than waiting to see whether it shows up as a pattern.
Set the next dose reminder before you close the app
The last thirty seconds of logging are the cheapest time to schedule the next reminder, because everything is already open and the date is already in front of you.
Set it for the day and time your prescriber's instructions specify — the reminder's job is to make you remember the schedule you were given, never to suggest one. If you use a phone, set it there rather than relying on remembering to set it later; if you use paper, write the next date at the top of the following page.
Then close it and get on with your day. The whole point of a good log is that it takes a few minutes and then leaves you alone.
What this record can and cannot do for you
A dose log can tell you what you took and when, show you your own patterns over time, and give you something concrete to bring to an appointment instead of a vague recollection. Those are real benefits and they compound.
It cannot tell you whether your dose is right, whether a symptom is expected, whether your medication is working, or what to do next. GLP-1 Tracker organizes what you enter and nothing more — it does not interpret your data, it is not a medical device, and it will never suggest a change to your medication. Every one of those questions belongs to your prescriber, and a good record simply makes that conversation better informed.
Frequently asked questions
What should I write down for my first GLP-1 dose?
Four things: the calendar date and rough time, the dose exactly as written on your prescription label, the injection site if it is injected, and one line about how you felt that day. Separately, copy down the full instruction your prescriber gave you, so you have a reference to check future entries against.
Do I need an app to log my doses?
No. A notebook with four columns does the same job, and so does a spreadsheet. An app helps mainly with the parts that are tedious on paper — reminders, injection-site history, and seeing a weight trend without drawing it yourself. Consistency matters far more than which tool you choose.
I already took a few doses without logging them. Can I still start?
Yes, and it is worth doing. Add the doses you can remember with the dates you are confident about, and mark anything you are unsure of as approximate rather than guessing precisely. Then log the next one properly. An honest partial history is much more useful than starting again from zero.
Should I log the dose before or after I take it?
After, and preferably within a few minutes. Logging beforehand risks recording a dose you then get interrupted and do not take, which is the one error that makes a record actively misleading. If you cannot log it immediately, most tools let you backdate the entry later.
What if my dose is different from what my prescription says?
Do not resolve that in your log. Write down what you actually took, and contact your prescriber or pharmacist about the discrepancy the same day. A tracking app records what you tell it; it cannot judge whether a difference matters, and this is exactly the kind of question that needs a person.
How long does it take before the log is useful?
You will get something out of it within about four weeks, when there are enough entries to see a rhythm rather than isolated points. It becomes genuinely valuable somewhere around eight to twelve weeks, which is usually the first time you look back and find a pattern you had not noticed while living through it.
