Is this medical advice?

No. Trace Peptide is a tracking and education tool. It is not a substitute for professional medical advice. Always work with a qualified clinician.

No. We can't — your data never leaves your device. There's no account, no server, no analytics.

Does it work with GLP-1 pens like Wegovy or Mounjaro?

Yes. Pen visualization shows the cartridge depletion exactly as the pen behaves. Weekly schedules are first-class.

Can I export my data?

Yes. CSV, JSON full backup, and PDF clinician report — all available in Settings → Data.

Know what's in your system.

The calm peptide tracker for protocols, GLP-1, and everything in between.
