Protocol tracking

Track what you're
running. See what
it's actually doing.

Dose logs, injection site rotation, and biomarker trends in one place — private by default, built for people who take this seriously.

Spreadsheets forget. So do you.

Most people tracking a protocol end up in a notes app or a spreadsheet that gets abandoned by week three. Site rotation gets forgotten. Doses get logged inconsistently, if at all.

Notes app / spreadsheet
  • No structured history — just scrolling back through old entries
  • Site rotation tracked by memory, until the same spot gets hit twice
  • No link between what you're running and what's changing in your body
  • Abandoned by week three, most of the time
Peptrace
  • Every dose timestamped, searchable, and never lost
  • Interactive body map — always know which site is next
  • Weight and biomarker trends charted against your log
  • Built to be the one habit that actually sticks

Everything the tracking actually needs.

Built around the parts that matter and nothing that doesn't.

Dose logging

Log every dose in seconds, timestamped and searchable. No app-switching, no re-entering the same details twice.

Site rotation

An interactive body map tracks where you've injected and when, so you're never guessing which side is next.

Cycle management

Plan cycles and stacks ahead of time, and track how closely reality matched the plan.

Trends & graphs

Weight and biomarker trends charted over time, so changes are visible instead of anecdotal.

AI protocol summary

A plain-language read on what your logged data actually shows — patterns you'd otherwise have to dig for.

Peptide library

A reference library on hand while you log, so the details are never more than a tap away.

Built to be looked at, not just filled in.

Body map view

Interactive site rotation — every injection logged to a location, at a glance.

Trends view

Weight and biomarkers charted side by side with your logged doses.

What people say once it's the only thing they use.

★★★★★

"I've tried three different spreadsheets over two years. This is the first thing that's actually stuck past week one."

"The body map alone was worth it. I genuinely didn't realise how much I was guessing on rotation until I saw the history."

"No hype, no wellness-app nonsense — just clean logging that actually works. Exactly what I wanted."
