Truncated IGF-1 missing the first three N-terminal amino acids (DES (1-3) IGF-1) with reduced IGFBP binding and selective local IGF-1R activation; researched for muscle hypertrophy. In the Peppy catalog, IGF-1 DES is reconstituted from a vial and drawn up in units on an insulin syringe, dosed in mcg, typically as needed.

## Frequently asked

### How many units is 20 mcg of IGF-1 DES?

It depends on how the vial was mixed. Example: a 2 mg vial plus 2 mL of bacteriostatic water is 1 mg/mL, so 20 mcg is 0.02 mL, or **2 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 IGF-1 DES in Peppy?

Yes. IGF-1 DES 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 IGF-1 DES?

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/).
