Long-acting amylin analog from Novo Nordisk that slows gastric emptying and reduces food intake; researched for weight loss alone and combined with GLP-1 agonists. In the Peppy catalog, Cagrilintide is reconstituted from a vial and drawn up in units on an insulin syringe, dosed in mg, typically weekly, with a listed half-life of about 7 days.

## Frequently asked

### How many units is 0.3 mg of Cagrilintide?

It depends on how the vial was mixed. Example: a 5 mg vial plus 2 mL of bacteriostatic water is 2.5 mg/mL, so 0.3 mg is 0.12 mL, or **12 units** on a U-100 insulin syringe. Change the water and the units change. Use the calculator above with your own vial, and verify with your prescriber.

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

The Peppy catalog lists a half-life of about 7 days for Cagrilintide. 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 Cagrilintide in Peppy?

Yes. Cagrilintide 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 Cagrilintide?

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/).
