The peptide tracker
built for precision.
Dose logging, reconstitution math, PK curves, and injection site rotation — for peptide, hormone, supplement, and habit protocols.
All on-device. No accounts, no cloud, no tracking. Apple Health integrated.
Precision, in your pocket.

Different by design.
Protocol isn't a generic health tracker with peptides bolted on. Every decision was made for the serious self-experimenter.
Privacy by Architecture
vs. cloud-first appsMost health apps sync your data to servers they control. Protocol's architecture makes that impossible — there are no servers to send your data to. SQLite on-device, full stop.
Peptides + Supplements + Habits
vs. single-purpose trackersMost trackers handle one thing. Protocol handles your entire stack — peptides with titration, supplements with unit tracking, and daily habits — all in one protocol with one schedule.
PK Curve Visualization
vs. dose logs that stop at the logLogging a dose is table stakes. Protocol shows you estimated blood concentration over time using pharmacokinetic curves — so you understand when peptides peak, overlap, and clear.
Intelligent Site Rotation
vs. no rotation tracking at allNo other app tracks injection site rotation with a tap-anywhere 3D body map. Protocol learns your history and tells you the next best site — reducing scar tissue over time.
Export Everything, Always
vs. data locked in proprietary formatsYour dose logs, protocols, weight, metrics, and side effects export as standard CSV or a formatted PDF report — sharable with a provider, importable anywhere, owned by you forever.
Icon Stealth
vs. apps that out you on your home screenSwitch between the Protocol icon and a discreet shield icon. Your home screen stays private without losing quick access. A small detail that matters when it matters.
AI-powered. Built for biohackers.
Every feature designed around precision, privacy, and the reality of running a peptide protocol — with AI that actually knows your stack.
AI Research Assistant
Ask anything about your compounds — half-lives, interactions, dosing windows, side effects. Grounded in research, context-aware of your active stack. 50 queries/month included with Pro.
AI Stack Builder
Describe your goal — fat loss, recovery, longevity — and the AI builds a complete protocol with compounds, doses, and schedules. Review, edit, and activate it in one tap.
Track Every Dose
Build multi-peptide protocols with flexible scheduling — daily, twice daily, every X days, or specific days. Log peptides, supplements, and habits together. Track titration schedules and on/off cycles.
Own Your Rotation
Tap anywhere on the 3D body map to mark injection sites. Protocol learns your rotation history and suggests the next best site — reducing scar tissue and keeping your protocol optimal.
See Your Progress
Visualize blood concentration with PK curves. Track your 89-day streak, adherence rates, weight milestones, and earn achievements for dose milestones and consistency.
Your Data Stays Yours
No accounts. No cloud sync. No third parties. Everything lives on your device. Export everything as CSV or PDF — dose logs, protocols, weight, metrics, and more. Your data, forever.
Reconstitution Calculator
Built-in syringe draw guide calculates exact units for any dose. Enter peptide mass, water volume, and desired dose — Protocol shows you precisely where to draw on a 100 or 50-unit syringe.
Inventory Management
Track vials, remaining amounts, batch numbers, expiration dates, and vendor details. Low-stock alerts keep you from running out mid-cycle. Never lose track of what you have.
iPad Compatible
Full iPad support with a layout optimized for the larger screen. Every feature — dose logging, body map, PK curves, AI research — beautifully presented on any iOS device.
Apple Health Integration
Protocol writes your weight, body measurements, and mindfulness sessions to Apple Health automatically. Reads your sleep and heart rate to pre-fill your daily check-in.
