How to track it in Peptimes
Add serelaxin 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 “Not FDA-Approved”.
- Logging: the amount you took and how you feel. It’s logged with the route Other, so there’s no injection site to record.
- 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 serelaxin or any other compound.
