Regimen vs MyTRT: Which TRT Tracker Is Right for You? (2026)
Two apps, both built for guys on testosterone replacement therapy. MyTRT has been around a while and has a loyal following. Regimen is newer but covers more ground. Here's how they actually stack up.
Feature Comparison
| Feature | Regimen | MyTRT |
|---|---|---|
| TRT dose logging | Yes | Yes |
| Injection scheduling / reminders | Yes | Yes |
| Lab / biomarker tracking | Yes (via health metrics + Apple Health) | Yes (25+ biomarkers) |
| Half-life visualizer (blood level curves) | Yes | No |
| Medication-to-health-metrics correlation | Yes | No |
| Injection site rotation with body map | Yes | No |
| Compound library | 600+ compounds | TRT focused |
| Apple Health / Google Health Connect | Yes (weight, body fat %, heart rate, sleep, blood pressure) | Limited |
| Progress photos (side-by-side) | Yes | No |
| iOS + Android | Yes | Yes |
| Free tier | Yes (1 compound, all features) | Yes (core features) |
Regimen
Regimen is a TRT tracker that's completely free for tracking your testosterone with every feature unlocked. You get PK curves that show your estimated blood levels between injections, injection site rotation with a body map, and health metric correlation that connects your blood pressure, weight, body fat %, and resting heart rate to your dosing timeline via Apple Health or Google Health Connect.
The blood pressure correlation is particularly useful for the TRT community. You can see whether splitting your dose stabilized your blood pressure, or how your resting heart rate responded to adjusting your injection frequency. That's data your doctor will actually care about.
If your protocol grows beyond testosterone — HCG, an aromatase inhibitor, peptides — Regimen handles all of it with a 600+ compound library. Premium ($4.99/mo or $39.99/yr) unlocks multiple compound tracking.
MyTRT
MyTRT earned its reputation by being the TRT-specific app that actually worked when there weren't many options. The dedicated biomarker tracking with 25+ lab values is a genuine strength — if you're the kind of person who logs every blood panel in detail, MyTRT's lab section is built for exactly that. Your doctor will appreciate seeing trends across your panels.
The free tier covers core features, and both iOS and Android are supported.
The tradeoffs: MyTRT doesn't offer blood level curves between injections, health metric correlation, or injection site mapping. It's focused on TRT only, so if your protocol includes HCG, an AI, or peptides, you'll need a separate app for those.
