Which TRT Tracker App
Should You Use?

Most peptide and TRT tracking apps are iOS only and were designed for general peptide logging, not TRT specifically. One app is different. Here's the honest comparison.

The Detail

What TRT Users Need That General Apps Miss

Most peptide tracking apps were built for research peptides first — BPC-157, TB-500, Ipamorelin. TRT adds specific requirements: multiple injection sites per week on a rotation schedule (gluteal, vastus lateralis, deltoid), bloodwork every 90 days with a specific panel (Total T, Free T, Estradiol sensitive, Hematocrit), and ester-specific timing considerations. Logging "200mg testosterone" is not the same as logging the ester type, which determines the half-life and the timing of your next draw.

Protocol is the only free tracker that handles all of these: the TRT ester calculator shows free testosterone content per ester, the bloodwork tracker logs the full TRT panel alongside your protocol history, and the injection body map tracks site rotation automatically. For TRT users also running peptides (a common combination), Protocol logs both in the same app with the same interface.

The TRT-specific reference pages are at trttracker.health — bloodwork guide, testosterone ester calculator, and TRT + peptide stacking.

FAQ

TRT App Questions

Is there a TRT tracking app for Android?
Protocol is the only full-featured TRT tracker on Android as of June 2026. It logs testosterone dose, ester type, injection site, frequency, and bloodwork results on Android with full feature parity to iOS. PepTracker, Dose, and PeptideCalc are iOS only.
Can I track both TRT and peptides in one app?
Yes. Protocol handles multi-compound protocols including testosterone alongside research peptides. Each compound gets its own logging entry with independent dose, frequency, reconstitution data (for peptides), and injection site tracking. The PK plotter shows active blood concentration curves for multiple compounds simultaneously — useful for timing peptide doses around testosterone peaks and troughs.
