Redose
The best retatrutide tracker helps you stay consistent with a demanding weekly titration schedule, and Redose is purpose-built for that job. Available on iPhone and Android, Redose handles dose logging, injection-site rotation, side-effect notes, and weight progress so you can focus on your goals instead of managing spreadsheets. Redose also logs your calories, food, macros, and water intake alongside your doses, so you do not need a separate calorie app.
Retatrutide is an investigational triple agonist (GLP-1, GIP, and glucagon receptors) that has shown strong results in phase 2 clinical trials but has not yet received FDA approval. People accessing it through research programs or compounding pharmacies have an especially strong need for careful self-tracking, because titration schedules are precise and side-effect patterns matter.
Why track retatrutide (investigational) with Redose
Staying on a multi-month titration without missing a dose or losing track of how your body is responding is hard without the right tool. Redose covers every piece of that picture:
- One-tap dose logging. Record each weekly injection in seconds. No forms, no friction.
- Body-map injection-site rotation. Tap your exact injection site on an interactive body map after each dose. The app shows recent sites so you can rotate intelligently and avoid tissue buildup.
- Full titration schedule support. Enter your starting dose and escalation steps, and Redose tracks where you are in the schedule at all times. Weekly reminders mean you never miss a dose.
- Side-effect and symptom journal. Log nausea, appetite changes, fatigue, GI symptoms, or any other notes right after logging a dose, while the details are fresh. Patterns become visible over weeks.
- Weight, food, and metabolic tracking. Log your weight and meals alongside your doses. Redose syncs with Apple Health (iPhone) and Health Connect (Android) so your full health picture is in one place.
- Adherence dashboard and trend charts. See your dose streak, weight trend, and symptom timeline at a glance. Real data makes follow-up conversations with your prescriber far more productive.
Track your food and water too
On a GLP-1 like retatrutide, appetite drops significantly, which makes it easy to under-eat protein and forget to drink enough water. Both matter for preserving muscle and avoiding fatigue during a long cycle. Redose lets you log meals, calories, and macros alongside your injections, so your nutrition data and dose history trend together in one dashboard. You can also log daily water intake to keep hydration consistent. See the calorie tracker feature at /features/calorie-tracker and the water tracker feature at /features/water-tracker for details on how those tools work inside Redose.
How it works
- Set your medication and dose. Add retatrutide as your medication, enter your starting dose and titration steps, and choose your injection day and reminder time. Takes about two minutes.
- Log each dose in one tap. When your reminder fires, open Redose, confirm the dose, pick your injection site on the body map, and add any quick notes. Done in under ten seconds.
- Watch your progress build. Your adherence rate, weight trend, symptom log, and injection-site history all update automatically. Review them any time or export a PDF for your next prescriber visit.
What to track on retatrutide (investigational)
Dosing varies and is always set by a clinician. For context, the phase 2 trial (New England Journal of Medicine, 2023) used the following weekly subcutaneous schedule as a reference. Your prescriber sets your personal schedule.
| Week range | Typical trial dose | Notes |
|---|---|---|
| Weeks 1-4 | 0.5 mg weekly | Starting / tolerance phase |
| Weeks 5-8 | 1 mg weekly | First escalation |
| Weeks 9-12 | 2 mg weekly | Second escalation |
| Weeks 13-16 | 4 mg weekly | Third escalation |
| Weeks 17-20 | 8 mg weekly | Fourth escalation |
| Weeks 21-24 | 12 mg weekly | Fifth escalation |
| Week 24+ | Up to 24 mg weekly | Maximum studied dose |
Compounded retatrutide protocols often differ from the above. Concentration, reconstitution volume, and escalation pace all depend on your specific preparation. Use the free reconstitution and dose calculators at /calculators to double-check your math before every injection.
Built for the whole journey
Retatrutide cycles typically run six months or longer, and managing that span involves more than just logging shots.
Vial and pen inventory. Redose tracks how many doses remain in each vial and sends reorder reminders before you run out. When you are sourcing a compounded peptide, running dry mid-cycle is a real risk. Staying ahead of it is easy with live inventory.
Apple Health and Health Connect sync. Weight, steps, heart rate, and other body metrics flow automatically into Redose from your wearable or health app. Seeing your metabolic data alongside your dose history gives context that individual data points cannot.
Doctor-ready PDF export. Generate a clean summary of your full dose history, weight trend, and symptom notes with one tap. Bring it to your next appointment or send it directly to your prescriber. Clinicians who work with investigational compounds need good records, and Redose makes producing them effortless.
For context on how retatrutide compares to other GLP-1 and dual-agonist options, see the retatrutide science profile at /peptides/retatrutide and the best GLP-1 for weight loss comparison at /best/best-glp-1-for-weight-loss.
If you are also tracking injection-site rotation or other GLP-1 medications, the same Redose workflow applies across your entire protocol stack. And if side effects are your main concern, the dedicated side-effect tracker feature gives you structured logging for every symptom you want to monitor.
