Thymic peptide complex extracted from calf thymus; researched clinically in Russia for immune restoration and longevity effects in elderly populations. In the Peppy catalog, Thymalin is reconstituted from a vial and drawn up in units on an insulin syringe, dosed in mg, typically in cycles.

## Frequently asked

### How many units is 5 mg of Thymalin?

It depends on how the vial was mixed. Example: a 10 mg vial plus 2 mL of bacteriostatic water is 5 mg/mL, so 5 mg is 1 mL, or **100 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.

### Can I track Thymalin in Peppy?

Yes. Thymalin 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 Thymalin?

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/).
