Regimen tracks TRT protocols across testosterone cypionate, enanthate, propionate, and Sustanon. Built-in TRT dose calculator converts weekly mg to per-injection mL. Track Total T, Free T, SHBG, Estradiol, Hematocrit, and PSA over time with lab integration. Pharmacokinetic modeling shows peak and trough levels for any injection frequency (weekly, twice-weekly, EOD, daily microdosing). Multi-compound friendly. Free for one compound; Pro is $4.99/month.
Daily, weekly, EOD, custom, as-needed. Stay consistent with smart reminders for every cadence.
Set your cycle duration and get alerts when it's time to cycle off, take a break, or restart.
Reconstitution, reverse BAC, TRT oil, and intranasal. Regimen handles the complex math, so you don't have to.
Track your vials, pens, and pills. We'll let you know when you're running low.
Regimen connects your doses, levels, check-ins, and blood work to what actually changes in your protocol. Measured against your own baseline, not population averages.
What's helping, what's not, and what's worth keeping an eye on.
Whether you inject every 3.5 days, every other day, or daily - Regimen schedules your exact protocol and reminds you at the right time.
Testosterone + HCG + AI + supplements. See your complete protocol on one screen instead of scattered across calendars and notes.
Correlate your injection history with weight, sleep, heart rate, and energy from Apple Health. Stop guessing if your protocol is dialed in.
Log each injection with date, ester, dose in mg or mL, and site. The app keeps a continuous protocol history regardless of how your dose, ester, or frequency changes over time.
Yes. The TRT calculator handles weekly mg to per-injection mL conversion based on your ester concentration (typically 200 mg/mL for cypionate, 250 mg/mL for Sustanon). It also outputs insulin syringe units if you use a sub-Q protocol.
Yes. Full lab panel tracking includes Total T, Free T, SHBG, Estradiol (sensitive assay), Hematocrit, PSA, and any other markers you add. Each lab pull plots on the dose timeline.
Yes. PK modeling shows the steady-state testosterone curve for your specific protocol (ester, frequency, dose). Useful for seeing why daily microdosing produces different lab numbers than weekly injections at the same weekly total.
See the comparison table above and /blog/best-trt-tracker-apps-2026 for deeper coverage. Short version: those apps focus on TRT only. Regimen handles TRT plus any other compound (peptides, GLP-1, supplements) on one timeline, with PK modeling and built-in dose calculator.
Yes. HCG logs as a separate compound on the same timeline as testosterone. Many TRT users run both; the app keeps them on one screen.
Yes. Any injection frequency works (weekly, twice-weekly, every other day, daily). PK modeling shows the steady-state curve so you can compare protocols.
Yes. The free tier covers one compound, including TRT, with full dose logging, lab tracking, side-effect tracking, and Apple Health sync. Pro ($4.99/month) unlocks multi-compound tracking and Signals.
