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.

Protocol duration — pick 4, 8 or 12 weeks at setup. Doses stop prompting when the cycle ends, with a reminder 3 days before. Missed doses — forgotten doses now surface on the home screen, and you can log them for the day you actually took them. Vial tracking — track the vial you're drawing from in mg. Logged doses deduct automatically, with expiry and post-mix use-by dates. Multiple protocols of the same peptide — run an AM/PM split, or track for someone else, sharing one vial. Adjusting a dose mid-cycle is now a visible button on the protocol card, including "increase early" for ramping protocols. Fixes: side effects and interaction warnings are readable in full — tap to expand. Sub-milligram doses no longer round incorrectly. Large vials such as 1000mg NAD+ are far easier to set up. ### 1.6.6 — 2026-06-15 Light Mode Choose Light, Dark, or Auto in Settings > Display. Auto follows your device's appearance. 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. Faster & more reliable - Loads instantly from cache on a cold start — even offline (no more blank screen). - Apple Health data refreshes when you reopen the app and on pull-to-refresh. - More dependable push-notification startup. Privacy Offline-logged data is now encrypted at rest on your device. ### 1.6.1 — 2026-05-27 Bug fixes and improvements: • Push notification reminders now deliver reliably on iPhone • Log Entry: dose input no longer overflows the screen and stays readable while editing • In-app subscription purchases now complete correctly ### 1.60 — 2026-05-26 Bug fixes and stability improvements. Lab Notebook subscription unlocks unlimited protocols, encyclopedia, statistics, and data export. ### 1.5.0 — 2026-05-05 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
