Research Dosing Tracking GLP1
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Try free for 3 days —full access. Track peptides, calculate doses, and ask your personal AI Dr about BPC-157, Retatrutide, semaglutide, tirzepatide, GLP-1, MOTS-C & more.
MyPepDoc is your personal peptide tracking app with an AI doctor who knows your protocol by name.
Choose Dr. Lexi or Dr. Rax as your guide. They know your peptide, your dose, your schedule, and your cycle day. Ask them anything about your protocol — anytime, day or night.
Whether you're running BPC-157 for recovery, Semaglutide for weight management, CJC-1295/Ipamorelin for growth hormone support, or any other peptide, MyPepDoc keeps your entire protocol organized and gives you a knowledgeable companion every step of the way.
AI DOCTOR CHAT
Dr. Lexi is warm, encouraging, and celebrates your wins. Dr. Rax is direct, data-driven, and keeps you accountable. Both know your exact protocol and give personalized answers — not generic FAQs. Ask about dosing, timing, side effects, cycling, stacking, or anything related to your peptides.
SMART DOSE CALCULATOR
Enter your vial size and BAC water amount. MyPepDoc calculates your concentration, injection volume, and syringe units automatically. No more guessing or doing math on paper. See exactly how much to draw — displayed in both mL and units.
BLEND SUPPORT
Running a multi-peptide blend? MyPepDoc handles anchor-based dosing so every component scales correctly. Supports popular blends and custom combinations.
40+ PEPTIDE DATABASE
Browse detailed research on over 40 peptides including what they do, how they work, expected experiences, side effects, recommended timing, and FDA status. Every peptide entry is thoroughly researched and written in plain English.
PROTOCOL TRACKING
Track every dose — taken, skipped, or missed. See your adherence percentage, current streak, and weekly summary. Dr. Lexi or Dr. Rax checks in with personalized accountability messages.
CALENDAR VIEW
Color-coded monthly calendar shows your full protocol at a glance. See which peptides are due each day. Never lose track of where you are in your cycle.
REMINDERS THAT WORK
Customizable push notifications remind you before each dose. If you forget, an accountability check-in follows up. Set your preferred times for morning, afternoon, evening, and before-bed doses.
CYCLE MANAGEMENT
Set on/off cycling for any peptide. MyPepDoc tracks your cycle day automatically and reminds you when to start and stop. Supports continuous protocols too.
FLEXIBLE SCHEDULING
Daily, every other day, 2x per week, 3x per week, 5-on/2-off, weekly — with custom day selection for each. MyPepDoc adapts to however your protocol is structured.
CUSTOM PEPTIDES
Using something not in our database? Add any peptide or medication with custom dosing, scheduling, and tracking. MyPepDoc works with your protocol, not against it.
GUIDED SETUP
Adding a peptide is a conversation, not a form. Dr. Lexi or Dr. Rax walks you through every step — vial size, reconstitution, dose, schedule, cycling — and explains why each setting matters.

What's New in 1.1.2
• Split dosing — take a peptide more than once a day (e.g. morning and before bed) and we'll divide the dose, remind you for each, and track them separately.
• Pick your syringe — see your draw in insulin units or mL/cc, however you actually measure it.
• Clearer blend dosing — fixed the draw amount for stacked peptides like CJC-1295 / Ipamorelin.
• Doses in mcg and mg — recommendations now show both, so what you enter always matches.
• Bug fixes and polish.
