Peptide Tracker is used by over 100,000 people. Track peptides and GLP-1s in one free app. Build your stack, log every dose, manage vials and supplies, monitor injection sites, visualize estimated plasma levels, follow your progress, and connect with people using the same compounds. Whether you’re managing one compound or a complex stack, keep your schedules, dose history, and inventory organized in one place. TRACK YOUR PROTOCOL Build Your Stack Create protocols with custom doses, schedules, frequencies, and durations. Add common peptides in seconds or create your own custom compounds. Log Every Dose Record scheduled or past doses, add notes, track injection sites, and edit entries anytime. When you correct a dose or change the vial it came from, your inventory updates automatically. Manage Vials and Supplies Keep track of mixed and unmixed vials, concentrations, remaining volume, blend components, bacteriostatic water, and other supplies. Reconstitute a vial right in the app and always know what you have on hand. See Your Estimated Levels Visualize how each compound builds and fades over time with an estimated plasma level curve based on your logged doses and the compound's half-life. Stay on Schedule Optional reminders help you stay consistent. See taken, skipped, and missed doses at a glance, follow your week with a simple checklist, and watch your consistency build a night sky you can share. FOLLOW YOUR PROGRESS Track Your Weight Log your weight over time, follow the trend, and see your progress alongside the protocols you're running. Compare Progress Photos Take consistent progress photos with alignment tools that help you match your framing each time. Browse your photos by month, compare any two side by side, and share the result.

Peptide Injection Tracker is a focused, private way to organize your own injection records—without creating an account, seeing ads, or sharing a health profile. SEE WHAT'S NEXT Open Today for your next reminder, recent activity, weekly count, and a fast way to add an entry. A short setup checklist helps you add only the tools you want. LOG YOUR OWN RECORDS Record the peptide name, amount, unit, route, time, injection site, notes, and optional symptoms. Backdate entries when needed, then edit or delete them from your history. REVIEW ONE CALENDAR Build the schedule you already follow using selected weekdays or an every-N-days interval, a start date, optional end date, and pause/resume controls. Browse across months to see planned, completed, and missed occurrences. A same-day log completes the matching occurrence. The app does not supply a preset regimen. TRACK ACTIVE VIALS Enter a starting amount and your own low-supply threshold. Remaining supply is derived from matching injection logs, so editing, deleting, backdating, or changing a logged amount automatically reconciles the estimate. Optional expiry dates stay visible on the device. REVIEW SITE HISTORY Use the visual Sites screen to see when each location was last recorded. Color bands represent elapsed time only and do not provide medical guidance. KEEP YOUR RECORDS PORTABLE Review your full history for free. Pro adds PDF and CSV export, active-vial inventory, flexible schedules, and support for multiple peptides. REFERENCE TOOLS, WHEN YOU WANT THEM Open Settings to find the peptide library, amino acid reference, quiz, and general concentration tool. The concentration tool performs amount-per-volume unit math and does not calculate an amount to administer. PRIVATE BY DESIGN - Stored on your iPhone - No account - No ads - No analytics or tracking - Optional Face ID app lock Peptide Injection Tracker is for personal recordkeeping and educational reference only. It is not medical advice or a medical device, and it does not diagnose, prescribe, recommend, source, or verify any substance, amount, treatment, or protocol.
