How to track it in Peptimes
Add mazdutide in My Protocols and set the schedule you already follow: days of the week, times of day and a start date. Peptimes never suggests an amount when you log or schedule a dose. Its Library entry shows the status label “Approved outside the US”. In the US it is not FDA-approved. Innovent Biologics reports that China’s National Medical Products Administration (NMPA) approved its mazdutide injection in June 2025, with a second approval in September 2025. That approval doesn’t apply in the US, and other mazdutide products don’t share it.
- Logging: the amount you took and how you feel.
- Injection sites: each dose records the site, and Insights shows where you’ve injected and how recently. It never suggests where to inject next.
- Reminders and history: reminders at your times, Dose History, the Calendar and CSV or JSON export work as described on the peptide tracker app page.
Peptimes is a tracking app, not medical advice. Talk to a licensed clinician about your treatment. Peptimes doesn’t sell mazdutide or any other compound.
