Dose Track saves how you mixed each retatrutide vial, shows the syringe units for the dose you log, and counts what is left. It reminds you on your weekly day and keeps side effects and weight next to every shot.
Retatrutide is investigational and not FDA approved, so there is no label schedule. In the published trials it was given once a week, with the dose stepped up every 4 weeks; the trial arms are described as research on our retatrutide guide, not as advice.
In Dose Track, set it as a weekly medication and log the dose your protocol uses. Each change is recorded from its start date, so you can see how long you were on each one.
Retatrutide comes as powder in a vial that is mixed with bacteriostatic water. The table shows the strength after mixing for common vial sizes and water volumes, and how much each unit on a U-100 syringe holds. Enter your own vial and water in Dose Track and it shows the units for whatever dose you log.

Each row is something worth writing down for Retatrutide, why it matters for this medicine, and what Dose Track does with it.
| What to track | Why it matters | In Dose Track |
|---|---|---|
| Mixing math per vial | A powder vial's strength depends on how much water you add, and vial sizes vary. | Enter the vial mg and water once; each logged dose shows mL and units. |
| Weekly shot | Trials gave retatrutide once a week. | A weekly reminder on your day. |
| Dose changes | Log the dose your protocol uses; there is no approved schedule. | Record each change from its start date. |
| Vial left and date mixed | A mixed vial has a limited life in the fridge. | Each vial keeps its mix date, expiry and amount left; run-out alerts warn before it is empty. |
| Weight | Weight is the main outcome the trials measured. | Log weight or sync from Apple Health or Health Connect. |
| Side effects | There is no label listing side effects for retatrutide. | Quick picks for GLP-1 side effects, plus anything you type in. |
Retatrutide has no FDA label, so there is no official side-effect list. Dose Track has quick picks for the side effects people on GLP-1 medicines log most: nausea, constipation, diarrhea, reflux or heartburn, tiredness, low appetite, injection-site reaction and headache. You can type in anything else, set how bad it was, and see it next to the dose and the dose step you were on.
With no label, there is no official missed-dose rule for retatrutide. Missed weeks show clearly in your Dose Track history.
In Dose Track a missed dose stands out in your history, so you can see the gap and count from the right day.
Dose Track is a tracking app, not medical advice. It records what you and your prescriber decide; it does not recommend doses. Check any dose change with your prescriber.
