PeptideBros is the #1 research peptide tracker for managing injection protocols, logging doses, and monitoring your progress over time. Built by researchers, for researchers.
Whether you're tracking BPC-157, TB-500, GLP-1, or any other research peptide, PeptideBros gives you a simple, focused tool to stay consistent, organized, and informed.
PEPTIDE PROTOCOL MANAGEMENT
Create custom peptide protocols with your preferred dose, frequency, and schedule. Support for daily dosing, custom patterns (e.g. Mon/Wed/Fri), and interval-based schedules. Set your start date and let the app handle the rest.
INJECTION LOGGING
Log every injection in seconds — dose, injection site, feeling score, and notes. The app automatically rotates through your injection sites and tracks which site is next. Never lose track of where you injected last.
STREAK TRACKING
Stay motivated with automatic streak counting. Complete your scheduled doses and watch your streak grow. Miss a day and it resets — keeping you accountable to your protocol.
ADHERENCE & ANALYTICS
See your adherence rate across any time period. Understand your patterns with clear stats — daily, weekly, and monthly views. Track how consistently you're following your peptide protocol.
INJECTION SITE MANAGEMENT
Manage all your injection sites — abdomen, flanks, thighs, and more. The app tracks rotation automatically and shows your site history. No more guessing where to inject next.
PEPTIDE ENCYCLOPEDIA
Reference common research peptides directly in the app. Learn about mechanisms of action, typical dosing ranges, and half-lives. All reference material, no medical advice — just the facts.
JOURNAL & NOTES
Keep a daily journal alongside your tracking. Log how you're feeling, note any side effects, and build a personal record of your research experience over time.

Estimated Levels — new on the Stats tab
See how much of each peptide is still active in your system, based on its half-life. Each shows a live decay chart, a current estimated amount, and either an "Active" status (while you're dosing) or a "clears in" estimate once you've stopped. Half-life values are research-verified.
