TRT Log: Injection Tracker
Dose calculator, labs & vials
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your whole protocol in one quiet, private place.
TRT Log is a record-keeping app for anyone on an injectable therapy — testosterone, HCG, peptides, GLP-1 or hormone therapy. 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. 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
Everything stays on your device. No account, no cloud, no ads, no analytics.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixed: after three feedback prompts the app stopped asking permanently. The yearly window now resets the way Apple's own limit does. The prompt also arrives on the 2nd, 8th and 20th logged dose rather than every twelfth.
