Dose Track vs PepTracker

A side-by-side peptide tracker comparison — features, platforms, privacy, and price.

PepTracker and Dose Track are both peptide tracker apps for iOS and Android, and both cover the basics well — dose logging, a reconstitution calculator, and reminders. The difference shows up once your protocol gets serious: whether the app just logs your doses or actually models your levels over time.

Transparency note: Dose Track publishes this comparison. We describe PepTracker fairly from its public listing and website — confirm current features and pricing on its own page before deciding.

Where PepTracker is strong

PepTracker is a clean, approachable dose-log and protocol tracker for peptides, GLP-1 medications, and testosterone. Its built-in dose calculator converts vial amount, diluent volume, and target dose into the exact mL or insulin-syringe units to draw. If you mainly want straightforward logging plus a reliable calculator on both platforms, it does that job well.

Where Dose Track pulls ahead

Dose Track is the only one of the two that models true pharmacokinetics — every dose is charted as a decaying exponential against the compound's calibrated half-life and Tmax, so you see your actual plasma level between injections instead of just a log of dates. It ships with 600+ compounds, parses bloodwork PDFs on demand, rotates injection sites automatically, and keeps all health data on-device — nothing is sold or stored on a server. It runs on both iOS and Android.

The verdict

If you want simple logging and a dose calculator, PepTracker is a fine choice. If you want to actually see your plasma levels between shots, run many compounds, analyze bloodwork, and keep your data fully on-device, Dose Track is the more capable peptide tracker.

Frequently asked questions

Is Dose Track or PepTracker better for tracking peptides?+

Both are solid peptide trackers on iOS and Android. PepTracker is great for straightforward dose logging plus a calculator. Dose Track adds pharmacokinetic level charts based on half-life, 600+ compounds, bloodwork analysis, and fully on-device privacy — so it's the better fit for serious or multi-compound protocols.

Do both PepTracker and Dose Track have a reconstitution calculator?+

Yes. Both apps include a reconstitution calculator that turns your vial size and bacteriostatic water volume into the exact insulin-syringe units to draw for a target dose. Dose Track additionally charts the resulting plasma level over time using each compound's calibrated half-life.

Are PepTracker and Dose Track free?+

Both follow a freemium model: free core tracking with paid tiers for advanced features. Dose Track is free to download on iOS and Android, with an optional Pro tier that unlocks unlimited compounds, pharmacokinetic charts, and bloodwork analysis.
