Nine-amino-acid pituitary hormone that mediates uterine contraction, milk ejection, and social bonding; FDA-approved (as Pitocin) for labor induction and postpartum hemorrhage control. In the Peppy catalog, Oxytocin is a pre-mixed injection, dosed in units, typically as needed, with a listed half-life of about 6 minutes.

## Frequently asked

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

The Peppy catalog lists a half-life of about 6 minutes for Oxytocin. After roughly five half-lives, about 30 minutes, 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 Oxytocin in Peppy?

Yes. Oxytocin 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 Oxytocin?

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/).
