Why Protocol

Different by design.

Not a generic health tracker with peptides bolted on. Every decision was made for the serious self-experimenter.

Privacy by Architecture

vs. cloud-first apps

Most health apps sync your data to servers they control. Protocol makes that impossible — there are no servers to send your data to. SQLite on-device, full stop.

No server. No leak.

Peptides + Supplements + Habits

vs. single-purpose trackers

Most 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.

Your whole stack, one app.

PK Curve Visualization

vs. dose logs that stop at the log

Logging a dose is table stakes. Protocol shows estimated blood concentration over time using pharmacokinetic curves — so you understand when peptides peak, overlap, and clear.

See what is actually happening.

Intelligent Site Rotation

vs. no rotation tracking at all

No 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.

Smart rotation, not guesswork.

Export Everything, Always

vs. data locked in proprietary formats

Your 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.

Your data is portable. Period.

Icon Stealth

vs. apps that out you on your home screen

Switch 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.

Private by default.

Everything you need

AI-powered. Built for biohackers.

Every feature designed around precision, privacy, and the reality of running a peptide protocol.

AI · Pro

AI Research Assistant

Ask anything about your compounds — half-lives, interactions, dosing windows, side effects. Knows your active stack. 50 queries/month with Pro.

AI · 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, activate.

Dose Logging

Track Every Dose

Multi-peptide protocols with flexible scheduling — daily, twice daily, every X days, or specific days. Peptides, supplements, and habits together. Titration and on/off cycles included.

Body Map

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 over time.

Analytics

See Your Progress

Blood concentration via PK curves. Streaks, adherence rates, weight milestones, and achievements for consistency and dose milestones.

Privacy First

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.

Calculator

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.

Inventory

Inventory Management

Track vials, remaining amounts, batch numbers, expiration dates, and vendor details. Low-stock alerts keep you from running out mid-cycle.

iPad

iPad Compatible

Full iPad support built for the larger screen. Every feature — dose logging, body map, PK curves, AI research — runs natively on any iOS device.

Pro

Apple Health Integration

Protocol writes your weight, body measurements, and mindfulness sessions to Apple Health automatically. Reads sleep and heart rate to pre-fill your daily check-in.
