Keep every peptide and compound protocol organized in one private place — built for people who want a real system of record for their own tracking, not a generic pill reminder.

No cloud. Just your data, on your phone. WHY PEPX • Purpose-built for peptides and compounds — not a one-size-fits-all habit tracker • Everything in one place: protocols, doses, inventory, bloodwork, body metrics, and photos • Private by design: your records stay on your device, protected by Face ID / Touch ID • Works fully offline — nothing to sign up for TRACK EVERY DOSE • Build multi-compound protocols with schedules, titration steps, and on/off cycling • Log doses fast — mark taken, skipped, late, or missed, and edit anytime • Discreet reminders that never reveal what you're tracking unless you choose to • Injection-site rotation with an interactive body map and next-site rotation reminders based on your own log DO THE MATH, NOT THE GUESSWORK • A general reconstitution & concentration calculator — does the math on the values you enter (no dose recommendations, not medical advice) • Convert between concentration, volume, and syringe units • Save and reuse your own calculations • Visualize estimated compound levels over time from published half-lives • A built-in reference list of compounds for your own record-keeping — for general information only, not medical advice — plus add your own entries SEE YOUR PROGRESS • Weight, body composition, vitals, sleep, hydration, and nutrition • Daily check-ins for mood, energy, sleep quality, and how you feel • Progress photos with side-by-side comparison and charts • Bloodwork and lab tracking with reference ranges over time NATIVE TO YOUR iPHONE • Home Screen and Lock Screen widgets for your next dose • Apple Watch companion to view and log doses from your wrist • Control Center, Action Button, and Siri shortcuts to log in a tap • Optional Apple Health sync across weight, body comp, vitals, activity, nutrition, hydration, sleep, and mindful minutes YOURS TO KEEP — OR DELETE • Export a clean PDF or CSV to share with your healthcare provider • Permanently erase all of your data, anytime, with one action • Available in English, Português, and Español PepX is a personal tracking and logging journal.
