Peptide AI is a peptide and GLP-1 tracker with an AI coach that reads your own logs. Log every dose in two taps, get reminded when it's due, and rotate injection sites on a 20-site body map, front and back. Track what's left in each vial, pen or pill bottle and get a nudge before you run low. Built for real protocols: BPC-157, TB-500, GHK-Cu, CJC-1295, Ipamorelin, GLP-1s like semaglutide, tirzepatide and retatrutide, and 55+ more compounds and blends. REMI, YOUR COACH — Ask about your own data and get answers backed by cited research. Remi reads your meals next to your doses, suggests short experiments and tells you whether they worked. TRACK — Daily check-ins, side effects after each dose, weight in lb or kg, goals and trends. Connect Apple Health, Oura, WHOOP, Garmin or Fitbit for sleep, HRV and recovery. COMMUNITY — Rooms for the compounds people run, and a weekly leaderboard with friends. EXPORT — A PDF of your dose history and health metrics to bring to your clinician. WIDGETS & WATCH — Log your next dose from a Home Screen or Lock Screen widget, or from Apple Watch. Logging doses and tracking your protocol are free. Remi, wearable sync, PDF export and some Track insights need a subscription. Peptide AI is for tracking and education only. It doesn't give medical advice or tell you how much to take: your dose comes from your clinician. Consult a licensed clinician before starting or changing any protocol.
