Its listing describes a protocol builder with cycles, 5-on/2-off and custom frequencies, a dose calendar with streaks, vial inventory with run-out projection, reconstitution math with a syringe diagram, a body-map heat map of injection sites, an estimated on-board level curve, weight and body-composition charts, progress photos with compare and time-lapse, an AI advisor and a moderated peer forum. Its site says protocol data stays on the device with optional iCloud sync.
The download is free; the listing says protocol tracking, the full library, advanced analytics and AI chat require a subscription.

Who each one suits
For the protocol itself the two are comparable. The choice comes down to what else you want in the same place.
When is PeptidePal the better choice?
If you want a protocol-only tool with a community built in, or you prefer your protocol data kept on the device. PeptidePal's peer forum, streaks and time-lapse progress photos are features Pep AI does not center on.
When is Pep AI the better choice?
If your protocol sits alongside a GLP-1 and weight goals, and you want food and symptoms on the same timeline. Pep AI logs meals by photo, barcode, menu scan or search with protein, fiber and water goals, rates side effects symptom by symptom, pulls weight, steps and sleep from Apple Health or Health Connect, and can produce a PDF report for your provider.
Moving a protocol into Pep AI
There is no import between the apps, but a protocol is quick to re-enter because the vial is what carries the math.
- Add each compound with its schedule, including cycle length and off-weeks if you run them.
- Add the vial you are currently using with its amount, the water you added and the date you mixed it, so every dose converts to syringe units correctly.
- Log your last dose and site for each compound so reminders and rotation start in the right place.
- Keep screenshots of your older history if you want the full record.
Key takeaways
- Both apps handle protocols, vials, reconstitution, injection sites and estimated levels.
- PeptidePal adds a peer community and keeps protocol data on the device.
- Pep AI adds food and nutrient logging, a grouped side-effect tracker, health sync and PDF reports.
- Both need a subscription for their main tracking features.
Your protocol, and everything around it.
