Compound library

The compounds people track in Peptilot, documented: what each one is, its published half-life, and what trackers commonly log alongside it. Educational reference only — never a recommendation.

In the app, this library is searchable and extensible — you can add fully custom compounds with their own units, half-life, and schedules. Try the reconstitution calculator or the half-life charts for any compound above.

Educational information for people who track their protocols — not medical advice, and never a recommendation to use any compound. Always work with a qualified healthcare provider.

Track any of these — or your own custom compounds — with dose logs, level charts, and reminders.
