Protocol: Peptide Tracker

You're managing real protocols with real compounds. You need an app that's a peptide calculator, tracker, inventory manager, while tracking injection sites and dose frequency.

Protocol is the last app you'll ever need to track peptides, supplements and habits.

Find out why thousands of iOS users choose Protocol.

Protocol is the only peptide tracker built for serious self-experimenters —
with pharmacokinetic curves, three built-in AI tools, reconstitution math,
injection site rotation, and the only app that tracks peptides, supplements,
and habits together in one protocol.

Everything stays on your device. No account. No cloud. No one has your data but you.

Try Pro free for 14 days. No commitment required.

COMPLETE PROTOCOL TRACKING
The only peptide app that combines peptides, supplements, and habits in one
protocol. Run an injury stack with injectables, daily collagen, and your
rehab routine — tracked together with one adherence score. No other app does this.

THREE AI TOOLS BUILT IN
Research Assistant: Ask anything about your stack in real time. Half-lives,
dosing windows, interactions, side effects. Answers from research — not generic
internet responses.

Check-in Coach: After every daily check-in, the AI analyzes your actual logged
data and gives you a personalized read on what's working.

AI Stack Builder: Describe your goal and the AI generates a full protocol with
compounds, doses, and schedules. Review, edit, and activate in one tap.

RECONSTITUTION MATH, SOLVED
Enter your peptide amount, vial volume, and target dose. Get exact BAC water
volumes and syringe draw units instantly. The concentration slider lets you dial
in your preferred draw size. No more guessing.

PHARMACOKINETIC CURVES
See exactly where any compound is in your system right now. Peak concentration,
half-life decay, and optimal dosing windows — visualized in real time as you
log doses. All compounds on one chart simultaneously.

TRACK EVERY DOSE
Find over 81 compounds and schedule daily, every X days, titration schedules, on/off cycles. Smart notifications so you never miss a dose.

INJECTION SITE ROTATION
Interactive 3D body map. Front and back views. Tap to log, pinch to zoom. Protocol learns your rotation history and
suggests the next optimal site — reducing overuse and keeping your protocol precise.

INVENTORY MANAGEMENT
Track vials, remaining amounts, batch numbers, expiration dates, and vendor
details. Low-stock alerts before you run out mid-cycle.

PROGRESS TRACKING
Daily wellness check-ins, weight tracking, body measurements, progress photos,
and adherence streaks. Navy method body fat calculation. See how your protocol
is actually performing.

EXPORT EVERYTHING
Full data export as CSV or PDF — dose logs, protocols, weight history, body
metrics — shareable with your healthcare provider.

APPLE HEALTH INTEGRATION
Reads steps, sleep, and heart rate. Writes weight, body measurements, and
mindfulness sessions back to Apple Health.

PRIVATE BY DESIGN
No account required. No cloud sync. No data collection. Everything lives locally
on your device. Data Not Collected — verified by Apple. Face ID lock and Stealth
Mode available.
