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.
