## Frequently asked

### How long does Trulicity stay in your system?

The Peppy catalog lists a half-life of about 4.5 days for Trulicity. After roughly five half-lives, about 3.2 weeks, most of a single dose has cleared. That is an estimate from the half-life, not a measurement, and individual clearance varies.

### Can I track Trulicity in Peppy?

Yes. Trulicity is one of 123 compounds built into Peppy, with its form, unit and typical frequency prefilled. Add it as a protocol, set your schedule, and Peppy handles the countdown, the log and the reminders (Pro).

### Where should I inject Trulicity?

Follow your prescriber's instructions. For subcutaneous shots the GLP-1 labels list the abdomen, thigh and upper arm and say to rotate. Peppy's body map has 13 sites, suggests the next one, and shows when each was last used. Read the [site rotation guide](https://peppytracker.com/guides/injection-site-rotation/).
