PepLedger — Peptide & GLP-1 Protocol Tracker

PepLedger is an iOS app built for people who actually run a protocol —

peptides, GLP-1s (semaglutide, tirzepatide), TRT and hormones, SARMs,

nootropics, supplements, medications — and are done tracking it in

spreadsheets, notes apps and memory. It was built to have the most complete

feature set of any tracker in this category. Here is everything it does:

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 instead of guesswork.

• Smart reminders — per compound and per schedule; never miss or double a

dose.

• "What's Active Now" — every dose decays on its half-life curve, so the

dashboard shows what is actually in your system right now, with an average

saturation figure across your protocol.

• Half-life decay charts per compound — see the days-to-clear at a glance.

• Live home-screen widget — active compounds and next dose without opening

the app.• Fact Check — paste any claim you read online ("X melts fat", "Y heals in

a week") and get a research-based verdict with sources.

• Research tab — organized reference material next to your log.

PROGRESS

• Bloodwork logging — labs stored beside the protocol they belong to, so

changes line up with what you were taking.

• Progress photos and measurements — timeline view.

• Apple Health sync and data export.

TRUST & PRIVACY

• Data stays on your device; no account required to start; no selling or

supplying of any compound, ever.

• Free reconstitution calculator (mg → units, bacteriostatic water math) on

the website — no account, no subscription:

WHY IT'S DIFFERENT

Pill-reminder apps don't understand reconstitution, site rotation or weekly

schedules that blur together; glucose apps bury injectables three menus

deep. PepLedger is built around the actual questions injectables raise —

how much, where, when, and is it still active — and adds the research layer

(AI Assistant + Fact Check) that this space badly needs.

medical advice.

KNOWLEDGE

• Compound library — 463 compounds with typical dose ranges, half-lives,

categories and notes already filled in; search and filter by category; save

any compound straight into your protocol.

• AI Assistant — ask protocol questions in plain language and get answers

with cited research sources instead of forum hearsay.
