Frequently asked questions

Yes. Every tool on this page is free, no sign-up. The Pepio iOS app is also a free download with an optional Pepio Plus upgrade for advanced tracking.

No. Pepio's tools are for self-tracking and educational organisation only. Always follow instructions from your licensed clinician, pharmacist, or medication label.

The calculators and trackers run entirely in your browser. We do not store your inputs on any Pepio server. The AI assistants temporarily send your input to a language model so it can structure the response — Pepio does not retain it.

The tools cover semaglutide (Wegovy, Ozempic), tirzepatide (Mounjaro, Zepbound), compounded versions of both, and common research peptides (BPC-157 included). The Pepio iOS app supports custom user-defined medications too.

Pepio for iOS handles the long-term tracking: durable history of every dose, push reminders, injection-site rotation memory, weight + symptom trends, and exportable logs for clinician visits. The web tools are great for one-off math; Pepio is built for the multi-month journey.

Stop tracking on Notes & spreadsheets.

Pepio remembers what you took, when, where you injected, and what changed.
