MyPeps is the home for your peptides. Log all your doses in one tap, view real-time active dose curves, track your vial stock and reconstitution, and stay on schedule with smart reminders. Requires a MyPeps paid subscription. Eligible new subscribers can start with a free 3-day trial. DOSE TRACKING IN ONE TAP Log every injection with a single tap. Track dose amount, timestamp, and notes. View your full dosing history, edit past entries, and export everything to CSV when you need it. REAL-TIME ACTIVE DOSE CURVES See estimated active levels for every peptide you're running. MyPeps uses pharmacokinetic modeling (absorption and elimination rates) to plot 7-day decay curves, so you always know where you stand between doses. SMART SCHEDULING & REMINDERS Set your frequency: daily, every other day, 2x or 3x per week, weekly, or as-needed. Choose your dose time and MyPeps handles the rest with local notifications that keep you consistent. VIAL & RECONSTITUTION TRACKING Track your full vial inventory from lyophilized powder through reconstitution to depletion. Monitor remaining capacity, bacteriostatic water volumes, concentration per mL, and expiry dates. Get notified before a vial expires. YOUR TRACKING DATA STAYS ON YOUR DEVICE Your peptide configurations, dose history, notes, and Apple Health values stay on your device, with no account required and no cloud sync. Apple handles payments, and RevenueCat processes subscription information and paywall analytics. We do not attach your tracking or Apple Health data to those analytics. Export your complete dose history as a CSV file with custom date ranges and peptide filters.
