GnRH agonist branded as Zoladex; FDA-approved for advanced prostate cancer, breast cancer, and endometriosis as a subcutaneous depot implant. In the Peppy catalog, Goserelin is a pre-mixed injection, dosed in mg, typically as needed, with a listed half-life of about 7 days.

## Frequently asked

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

The Peppy catalog lists a half-life of about 7 days for Goserelin. After roughly five half-lives, about 5 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 Goserelin in Peppy?

Yes. Goserelin 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 Goserelin?

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/).
