PepLedger

PepLedger is an iOS app for anyone running an injectable or supplement protocol who is tired of spreadsheets and notes-app chaos. Log a dose in two taps, keep cycles organized, and see — live — how much of each compound is still active in your system based on half-life. A body map tracks injection sites so rotation actually happens; smart reminders make sure no dose is missed. What makes it different: a 463-compound library (peptides, GLP-1s, hormones, SARMs, nootropics, supplements) with typical dose ranges and half-lives already filled in; an AI Assistant that answers protocol questions with cited research sources instead of forum hearsay; and Fact Check — paste any claim you read online and get a research-based verdict with sources. A live home-screen widget shows what's active at a glance, bloodwork and progress photos live alongside the log, and Apple Health sync is built in. Data stays private on your device. The reconstitution calculator (mg → units) is free on the website with no account required. The app offers a 7-day free trial. PepLedger is a tracking and organization tool, not medical advice, and does not sell or supply any compound.
