The complete
protocol tracker.
Most apps track your peptides. Protocol tracks your entire protocol — peptides, supplements, and habits together, with three AI tools, Apple Health integration, and on-device privacy.

The Protocol Difference
A protocol isn't just your peptides.
Real optimization is a system — injections, supplements, and daily habits working together toward one goal. Protocol is the only app that tracks all three as one.
Full peptide stack with reconstitution math, dosing schedules, cycling, and injection site tracking built in.
Track oral supplements, vitamins, and nootropics alongside your injectable stack. Same adherence tracking, same today screen.
Non-compound behaviors that are part of your protocol. Sleep, hydration, training, rehab. Log them the same way you log doses.
Artificial Intelligence
Three AI tools. One app.
No other peptide tracking app has three distinct AI tools. Research, coaching, and stack building — all connected to your actual data.
Research Assistant
Ask anything about any compound anywhere in the app. Dosing, stacking, mechanisms, side effects, cycling recommendations. Pulls from research literature and formats responses with tables and structured sections. Available in inventory, catalog, protocol builder, and progress screens. Renameable — make it yours.
Check-in Coach
After you complete your daily check-in — energy, mood, sleep, pain, libido, appetite, side effects — the coach reads your actual logged numbers and gives you a personalized analysis. It noticed HRV spikes. It flags when mood holds strong despite poor sleep. It recommends specific adjustments based on what you actually logged. Not generic. Your data, analyzed.
AI Stack Builder
Inside Create Protocol. Describe your goal — 'I want to optimize recovery from a shoulder injury while maintaining muscle during a caloric deficit' — and the AI asks clarifying questions before proposing a full protocol. Reviews, edits, and approves in one workflow. The fastest path from goal to tracked protocol.
Active Levels Chart
Every compound in your stack plotted on one timeline simultaneously. See when each peptide peaks, how long it stays active, and when it clears — all compounds at once.
No other peptide app shows you this.
Everything in one place.
Every feature Protocol has — documented. Built for serious health optimizers who run complex stacks and demand precision.
Complete Protocol Tracking
The only app that combines peptides, supplements, and habits into one unified protocol. Run an Injury Protocol with TB-500 injections, BPC-157 twice daily, a collagen supplement, and your daily rehab routine — all under one color-coded protocol with one adherence score.
Active Levels Chart
See every compound in your stack plotted on one timeline simultaneously. Cmax, peaks, clearance, and trough — all compounds, all at once. No other peptide app shows you this. Tap to expand full screen.
AI Research Assistant
Ask anything about any compound — dosing, mechanisms, stacking, side effects. Available throughout the app in your inventory, catalog, and protocol screens. Renameable. Pro subscribers get 50 queries/month. Credits never expire.
AI Check-in Coach
After every daily check-in, the coach analyzes your actual logged data and gives you a personalized read. Not generic advice — it reads your numbers, flags patterns, and suggests adjustments based on what you specifically logged.
AI Stack Builder
Describe your goal and the AI asks clarifying questions before proposing a full protocol tailored to your situation. The fastest way for newer users to get started — the AI designs the stack, you decide what to track.
Apple Health Integration
Bidirectional. Protocol reads steps, active calories, heart rate, HRV, and sleep data automatically. It writes your weight, body measurements, and mindfulness sessions back to Apple Health. Protocol becomes the central hub for all your health data.
3D Body Map with Custom Zones
Full 3D rendered front and back body views simultaneously. Tap anywhere to log your injection site. Color-coded history: green = rested, orange = recent, red = today, blue = never used. Pinch to zoom for precision. Create custom labeled zones like 'left knee repair zone' — Protocol tracks it like any other site. No other app shows front and back together.
Reconstitution Calculator
Add a peptide to your inventory and Protocol guides you through reconstitution step by step. Choose from Precise (10 units), Easy Draw (20 units), or Large Draw (50 units). Every future dose log references your exact reconstitution numbers automatically.
PK Curve Modeler
View the pharmacokinetic profile for any compound in your inventory. Model 1, 4, 8, or 12 doses to see how blood concentration accumulates. Peak, trough, time to peak, and average all displayed. Available for every compound in the catalog.
Protocol Templates
15 ready-made protocol templates covering common goals — BPC-157 + TB-500 healing stack, Semaglutide FDA titration schedule, CJC-1295 + Ipamorelin growth hormone stack, and more. Load any template, then customize to your situation.
Titration Protocols
Toggle on titration mode when creating a protocol and Protocol auto-advances your dose at each step. No manual adjustments — the app manages the ramp for you. Essential for GLP-1 titration schedules and new compound onboarding.
Flexible Scheduling
Daily, twice daily, every X days, specific days of the week, weekly, and custom cycles. Set on-weeks and off-weeks for cycling protocols. Every schedule type the peptide community actually uses.
Progress Photos
Front, side, and back pose photos organized by date. Pull any two dates side by side in the Compare view to see the change. The more consistently you shoot, the more powerful this becomes. Shareable achievement badges for milestones.
Body Measurements & Body Fat
Track neck, chest, waist, hip, biceps, and thighs. Protocol uses neck, waist, and hip to calculate body fat percentage using the Navy method automatically. The more consistently you log, the more accurate your body fat tracking becomes.
Export for Healthcare Providers
Export your full activity log — timestamped doses, check-in scores, side effects, metrics — and send it directly to your healthcare provider or health coach. Protocol creates a record worth reviewing.
On-Device Privacy
No accounts required. No cloud storage. Your data never leaves your device. Add Face ID lock and Stealth Mode (changes the app icon) for complete privacy. Nobody else in this space leads with this.
49-Compound Catalog
Every compound in the catalog has dosing ranges, cycling recommendations, half-life, administration route, common uses, research notes, and a PK curve. Covers the full range — peptides, GLP-1s, GHRPs, cognitive compounds, immune peptides, and metabolic molecules.
Streak & Achievement System
Protocol tracks your consistency and rewards it. First dose, 10 doses, 50 doses, 100 doses, monthly streaks — each achievement is dated. Share badges to your community. 97% 7-day adherence means something when the app is holding you accountable.
Bloodwork & Lab Tracking
Log lab results and correlate biomarker trends with your protocol timeline. Track testosterone, IGF-1, estradiol, thyroid panels, and 80+ biomarkers. See exactly what your stack is doing to your bloodwork over time. Import via photo, PDF, or manual entry.
Protocol Cost Tracking
Know exactly what your protocol costs. Add purchase price to any inventory item and Protocol calculates cost per dose, cost per vial, and projected monthly spend for your entire stack — so you can budget your protocol like a professional.
Compound Interaction Checker
Instantly check how compounds in your stack interact with each other. 30 most common peptide pairs covered — synergy, redundancy, timing recommendations, and caution flags. No guessing whether BPC-157 and TB-500 work well together. They do. We'll tell you why and when to take them.
Stack Score & Radar Chart
AI scores your entire protocol across 6 dimensions — synergy, redundancy, side effect risk, practicality, goal alignment, and evidence quality — then visualizes it as a radar chart. See exactly where your stack excels and where to optimize. Flags obvious issues like running two GHRPs simultaneously.
