Testosterone. AI. HCG. 80+ lab markers. Protocol is the only app built for the complexity of a real TRT protocol — not just a dose logger with a reminder.
Most TRT trackers only handle the testosterone injection. Protocol tracks the full protocol — Test, AI, HCG on the same timeline, with the Active Levels chart showing where each compound sits in its half-life curve simultaneously. No spreadsheet does this automatically.

Total T, Free T, E2, SHBG, hematocrit, PSA — every panel logged with trend charts over time. Protocol tracks 80+ biomarkers. You can see your E2 trending before symptoms arrive and correlate it directly with your dosing timeline. This is the feature no other tracker on either platform offers.
Protocol handles the full stack. Testosterone, Anastrozole, HCG, BPC-157, and whatever else you're running — tracked together in one protocol with one adherence score. No other app does this. See TRT + Peptide Stack Tracking →
