Regimen is a TRT tracker app built to track TRT injections and bloodwork together: every testosterone injection logs in one tap, and your labs, scanned or typed in, plot against your dose history.
It handles weekly, every-three-day and daily microdosing schedules, converts your dose from mg to syringe units, suggests the next injection site, and plots your bloodwork against your dose history so a change in a marker sits next to whatever you changed. It tracks HCG, anastrozole and peptides alongside testosterone. On iPhone and Android, rated 4.8 across the App Store and Google Play.
You log the shot. Regimen connects it to how you feel and what your labs say.
Weekly, twice weekly, every three days, or daily microdosing. Set it once and the reminders follow your actual protocol instead of a generic daily nag. HCG, anastrozole and any peptides sit on the same schedule, because almost nobody is on testosterone alone.
Testosterone esters peak and fall on their own schedule, and the trough is usually where people feel it. A chart of your estimated levels makes a rough day before your next shot make sense, and shows what changing frequency would actually do.
The things you actually notice, logged in seconds and plotted on the same timeline as your injections. After a few weeks Regimen tells you in plain words what repeats, so a good month is something you can point at rather than something you think you remember.
Intramuscular or subcutaneous, the standard spots or your own, a separate rotation for each compound. Regimen remembers where the last shot went, shows where the next one goes, and rests a spot when you tell it to. Years of TRT is a lot of injections, and rotation is the difference between comfortable and scarred.
Total testosterone, free testosterone, estradiol and hematocrit, plotted against your injections. When a marker moves you can see what you changed and when, instead of guessing between six-month panels.
Regimen connects the dots. Every injection, symptom, lab result and dose change lands on one timeline, and built-in pattern detection tells you in plain words what it finds across them, so you can see what changed when you moved to every three days, or whether that rough week lines up with anything real. It handles HCG, anastrozole and peptides in the same view, because almost nobody is on testosterone alone.

The reason was switching from cypionate… to propionate… a connection I hadn’t made before.”
★★★★★“Started TRT a little while ago and was just writing stuff down in notes. This app actually keeps me organized… reminders hit at the right time, and I can track my testosterone levels and how I’m feeling alongside my injection log.”
★★★★★“I’ve tried multiple apps for tracking TRT, peptide, and bioregulator protocols but this is the first one that actually fits how a real regimen works… Dosing and scheduling: multiple compound status (daily, EOD, weekly) with reminders that hit at the right times, not one generic daily alert.”

Testosterone replacement therapy is usually an injected ester - cypionate, enanthate or propionate - on a schedule that ranges from once a week to a small dose every day. The ester determines how fast it releases, which is why the same weekly milligrams can feel very different split across three injections instead of one.
The part people underestimate is the week itself. Levels peak a day or two after an injection and fall until the next one, and for many people the trough is where the symptoms live. A six-month lab panel captures one moment in that cycle. What happened in the weeks around it is the part nobody writes down.
| Schedule | What it does to the curve | Who tends to use it |
|---|---|---|
| Once weekly | Highest peak, deepest trough. | Simplest to keep up with; common starting point. |
| Twice weekly | Smaller swing between peak and trough. | The most common protocol adjustment. |
| Every three days | Flatter still. | People chasing stable energy and mood. |
| Daily microdose | Closest to flat. | Insulin syringes, smallest swing, most injections. |
Frequency is the lever people reach for when the weekly dose is right but the week still feels uneven. Changing it changes the shape of the curve, not the total. Dosing decisions belong with your prescriber.
These are the markers people on TRT most often watch between panels. What your prescriber orders and how often is their call; this is about keeping the results somewhere they can be compared.
| Marker | Why it is tracked | Cadence | Worth knowing |
|---|---|---|---|
| Total testosterone | The headline number. | Every panel | Timing vs your injection matters |
| Free testosterone | The fraction actually available. | Every panel | Moves with SHBG |
| Estradiol | Converts from testosterone. | Every panel | Drives a lot of how you feel |
| Hematocrit | Red blood cell concentration. | Every panel | The most-watched safety marker |
The value is not any single panel. It is the same marker measured the same way over time, next to the dose and schedule you were actually on when it was drawn.
This page is for tracking and education. It’s not medical advice, and dosing, frequency and lab decisions belong with your prescriber.
A TRT tracker app records every testosterone injection - the ester, the dose, the date and the site - and keeps it alongside your bloodwork and how you have actually been feeling, so the weeks between lab panels are not a blank. Regimen logs the injection on any schedule from weekly to daily microdosing, converts your dose to syringe units, rotates your sites, and plots total testosterone, free testosterone, estradiol and hematocrit on the same timeline as your doses.
Regimen. Each testosterone injection logs in one tap on any schedule, from weekly to daily, with the next injection site suggested. Your labs go in by scanning the report or typing them in, and total T, free T, estradiol, SHBG and hematocrit plot on the same timeline as your doses, next to an estimate of where your levels sit between shots. HCG and anastrozole sit alongside your testosterone. Free for one compound, no time limit; Premium if you track more than one. On iPhone and Android.
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.
Those apps track TRT and stop there. Regimen puts testosterone, HCG, anastrozole and any peptides on one timeline, estimates where your levels sit between injections, and plots your bloodwork against the doses you were actually on. If you only ever inject testosterone and never look at a lab result, a simpler app will do; if your protocol has more than one moving part, that is what this is built for.
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. More than half of Regimen users on TRT also track a GLP-1, and about half of GLP-1 users track something else alongside it.
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. Free for one compound, no time limit; Premium if you track more than one. The free tier includes dose logging, lab tracking, side-effect tracking and pattern detection.
