PepOS: Peptide Tracker

Edit doses on the fly. Browse 281 compounds with smart search. Unified PepOS Intelligence tier with 14-day free trial.

PepOS is the peptide protocol command center for biohackers who take optimization seriously.

PepOS is an educational tracking and journal app. Not medical advice. Always consult a licensed healthcare provider before starting any peptide protocol.

Track every dose, vial, and outcome. Build protocols by hand or let AI design them based on your goals. Close your daily rings — Execution, Progress, Recovery — and watch your 7-day optimization score climb.

APPLE HEALTH + AI INSIGHTS

Connect PepOS to Apple Health to see how your protocols are actually affecting your body. PepOS reads your weight, body composition, resting heart rate, HRV, and sleep data on your device and shows you trends alongside your peptide timeline. Weight entries you log in PepOS sync back to Apple Health automatically.

With your separate permission, Peppy — our AI assistant — can also use a 30-day summary of your Health metrics to give protocol-specific insights ("your HRV has improved 14 ms since starting your current protocol") instead of generic advice. AI data sharing is optional, granular, and can be turned off anytime without disconnecting Apple Health. Your health data is never shared with advertisers and never used to train AI models.
