App Comparison · TRT · 2026
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
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.
