TRACKING • Dose & cycle log — two taps: compound, amount, unit, time, injection site, note. • Cycle management — start/end dates, totals, active vs. completed cycles, streaks. • Injection-site body map — tap where you injected; rotation becomes visible. • Smart reminders — per compound and schedule; never miss or double a dose. • “What’s Active Now” — doses decay on their half-life curve, showing what is in your system now. • Half-life decay charts per compound. • Live home-screen widget — active compounds and next dose.

KNOWLEDGE • Compound library — 463 compounds with typical dose ranges, half-lives, categories and notes. • AI Assistant — protocol questions with cited research sources. • Fact Check — paste a claim, get a research-based verdict with sources. • Research tab — organized reference next to your log.

PROGRESS • Bloodwork logging beside the protocol. • Progress photos and measurements. • Apple Health sync and data export.

TRUST • On-device data; no selling compounds. • Free reconstitution calculator: https://www.pepledgerapp.com/reconstitution-calculator
