Stop juggling spreadsheets, notes, reminders, and reconstitution calculators.

Peptide Tracker gives you one place to manage your entire peptide protocol. Build your stack, track 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 peptide or a complex stack, Peptide Tracker keeps everything organized and easy to understand.

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.

Review Your History
Browse your complete dose history in a calendar and quickly see what you took, when you took it, and which protocol it belonged to.

BUILT-IN PEPTIDE TOOLS

Use built-in calculators for reconstitution, syringe-unit conversions, premixed blends, and half-life estimates without leaving the app.

CONNECT WITH PEOPLE ON THE SAME COMPOUNDS

Ask questions and hear from people who have actually used the compounds you're researching or tracking.

Share your own experience through structured answers, reply directly to others, and continue the conversation in open threads with quotes and mentions. Everyone participates under a username rather than a real name, with reporting, blocking, and community notes built in.

LEARN AND EXPLORE

Browse educational content covering peptide basics and use the Peptide Assistant for general peptide information.
