TRT Log: Testosterone Tracker

A testosterone tracker for your whole TRT protocol: log every injection, see an estimated level curve between doses, and keep your labs in your own units, private on your iPhone.

NEW IN 1.1: home and lock screen widgets, lab report scanning, and weight and blood pressure in your daily check-in.

TRT Log is a record-keeping app for testosterone therapy, and for anything you inject alongside it, such as HCG. Log a dose in seconds, rotate sites properly, watch your bloodwork trend, and walk into an appointment with a summary instead of a notes app.

TRACK A WHOLE STACK
- Run several protocols at once, each with its own schedule and reminder
- Daily, every other day, twice weekly, specific weekdays, every X days, or on/off cycles
- Smart site rotation suggests the spot you have rested longest, and alternates sides
- One reminder per dose: log it or snooze it right from the notification
- No marketing, no streaks, no re-engagement pings

BUILT-IN CALCULATORS, FREE
- Reconstitution: enter vial amount, bacteriostatic water and your dose, get the exact syringe units — and the nearest readable mark, so you know what you are really drawing
- Free testosterone from total T, SHBG and albumin, using the Vermeulen equation

BLOODWORK THAT MAKES SENSE
- 25 markers including Total T, Free T, Estradiol, SHBG, Hematocrit, PSA, lipids, thyroid and IGF-1
- Switch between ng/dL and nmol/L, pg/mL and pmol/L — enter results exactly as your lab reported them
- Every draw is tagged trough, peak or mid-cycle from your own dose history, because a number means something different at each

SEE WHAT HAPPENS BETWEEN DOSES
An estimated level curve, modelled from published half-lives and scaled to your own lab results. Shown as a percentage of your protocol's steady state, never as a clinical figure — because only a blood test shows your actual level.

VIALS AND SUPPLIES
Remaining amount, low-stock warnings, discard dates after reconstitution, and cost per dose.

DOCTOR-READY PDF
One tap to a summary of your protocols, laboratory results, administration history and check-ins.

PRIVATE BY DESIGN
Your doses, labs and notes stay on your device. No account, no cloud, no ads, no tracking.
