Peptide AI is a peptide tracker built for GLP-1s and broader peptide use. Track injections, doses, weight, side effects, notes, and progress in one place. Supports popular GLP-1 medications like Zepbound, Wegovy, Ozempic, and Mounjaro. A paid Peptide AI Pro subscription is required to access the app. Inside the app, members use the Home tab to log injections, nutrition, hydration, side effects, and daily notes; the Results tab to review weight and progress trends; and the Profile tab to manage reminders, Apple Health settings, and account preferences.

About

The Compound

Features
Read full description

You're already on a peptide protocol. What you need now is a tracker built for it — not another calorie counter. The Compound is built for people on semaglutide, tirzepatide, or retatrutide, whether you're getting pre-filled pens from a telehealth provider or working with compounded peptides. It handles everything generic health apps don't: titration schedules, injection timing, and side effect logging — all offline, all on your device. PROTOCOL ENGINE Set your compound and start date. The app calculates your titration schedule automatically — standard or slow pace — based on published clinical schedules. Every week you'll see your current dose, your next titration date, and what dose comes next. When life happens, you stay in control. Hold your dose for a week if side effects are rough. Titrate early if you're tolerating the current step well. Step back a dose if you need to. Switch between standard and slow titration at any point. When you reach your goal, enter maintenance mode — keep your dose weekly or stretch to bi-weekly injections. INJECTION LOG Tap once to log an injection. The app tracks every dose, timestamps each one, and tells you exactly how many days until your next shot — or flags it if you're overdue. Your full log is chronological, editable, and stays on your device. SIDE EFFECT LOG Log nausea, fatigue, constipation, vomiting, headache, and more — with severity and optional notes. Side effect history is charted alongside your dose progression so you can spot patterns. PROGRESS Weight, body fat, dose progression, and symptom history — charted over time against your protocol timeline. The data lives on your device. WHO IT'S FOR — Telehealth patients on Ozempic, Wegovy, Mounjaro, or Zepbound who want more than a paper schedule. — Self-administering users on compounded peptides who need a precise protocol tracker. — Anyone who wants a clinical-grade tool instead of a wellness app with motivational quotes. Note: retatrutide is Phase 3 and not FDA-approved. The app supports tracking it for research purposes only. The Compound does not provide medical advice. It is a tracking tool for people who already know what they're doing. $7.99/month or $54.99/year. No free tier. Your data stays on your device. Terms of Use: https://compoundprotocol.com/terms
