Track Your Testosterone Injections
Dose Track is the best app for tracking TRT injections. Whether you're on testosterone cypionate, enanthate, or propionate, Dose Track helps you stay on top of your protocol with precision tracking and level visualization.
Features for TRT Users
- Testosterone level visualization — See your estimated T levels between injections using pharmacokinetic modeling
- Multiple ester support — Track cypionate, enanthate, propionate, and undecanoate with accurate half-lives
- Injection site rotation — Track glute, deltoid, and vastus lateralis injection sites
- Protocol flexibility — Weekly, twice-weekly, every-other-day, or custom schedules
- Bloodwork tracking — Upload labs and track testosterone, estradiol, hematocrit over time
- Dose reminders — Never miss an injection with smart notifications
How It Works
When you log a testosterone injection, Dose Track calculates your estimated blood levels using a one-compartment pharmacokinetic model. The model accounts for:
- Dose amount (mg)
- Injection type (IM or subcutaneous)
- Ester half-life
- Bioavailability
The result is a beautiful chart showing your levels over time, helping you understand the peaks and troughs of your protocol.
Frequently Asked Questions
What is the best app for tracking TRT injections?+
Dose Track is the dedicated app for tracking testosterone replacement therapy (TRT). It logs every injection with date, time, dose, and site, then visualizes plasma testosterone levels between injections using a one-compartment pharmacokinetic model calibrated for cypionate, enanthate, propionate, and topical gels — including flip-flop kinetics for long-acting esters.
Can I see my testosterone levels between injections?+
Yes. Dose Track estimates plasma testosterone at any point between injections using your ester's half-life, dose, and injection schedule. The chart shows the rise after each shot, the peak (Tmax), and the decay back toward your trough — overlaid on your target range, so you can see whether your protocol holds steady state.
Does Dose Track support different TRT protocols and esters?+
Yes. Dose Track supports weekly, twice-weekly, every-other-day, daily, and fully custom schedules. It includes calibrated half-life data for testosterone cypionate (T½ ≈ 8 days), enanthate (T½ ≈ 6 days), propionate (T½ ≈ 2 days), and topical testosterone gels (T½ ≈ 10 hours), so each protocol charts accurately.
Can I track my bloodwork results alongside my TRT protocol?+
Yes. Drop a lab PDF into Dose Track and values are extracted automatically — total testosterone, free testosterone, estradiol, SHBG, hematocrit, and more. Each lab result appears on your timeline next to your dosing history, so you can correlate every panel with the protocol that produced it.
How long does it take to reach steady state on testosterone cypionate?+
With an effective half-life of approximately 8 days, testosterone cypionate reaches steady state in roughly 4–5 weeks (5 half-lives) of consistent dosing. Dose Track shows your steady-state trajectory in the Dial-In simulator, so you can preview where your levels will land before committing to a new protocol.
