A quiet, private logbook for the peptides, protocols, and progress you'd rather keep to yourself.
Organize compounds, rotate injection sites, and watch consistency build — all on-device and synced privately through your own iCloud.
Coming to the App Store See featuresBuilt around three ideas: nothing leaves your devices, the interface stays out of the way, and your protocol stays yours.
Every compound, dose, and note lives in your private iCloud. We never see your data — not the names, not the amounts, not the notes.
The coldest injection site is auto-suggested. Last quantities reappear as taps. Your most-used compound is pre-selected. Logging takes seconds.
Visual body map, half-life estimates, streak counters, and 18 preset compounds out of the box. Customize anything; add anything.
Pep is built on a simple promise: we don't see what you log. Here's what that means in practice.
No sign-up, no email required. The app works the moment you open it.
Everything you log is stored in your personal iCloud database. We have zero access to that data.
We track mechanical events ("app opened", "log saved") with no compound names, no dosages, and no notes attached.
We don't sell, rent, or share your data with advertisers. Ever.
Pep is a manual organization logbook. It does not calculate dilutions, recommend dosages, or provide medical advice. For any health decision, talk to a qualified healthcare professional.
