Testosterone Cypionate — TRT Injectable Ester
Regimen is the testosterone cypionate tracker app built for the most commonly prescribed TRT ester in the United States. Whether you're injecting weekly, twice weekly, or daily microdosing with insulin syringes, Regimen logs every dose, models your estimated testosterone levels with PK curves based on cypionate's ~8-day half-life sourced from published pharmacokinetic data and FDA prescribing information, and correlates your protocol to blood pressure, energy, mood, and body composition. Use the TRT dose calculator to calculate your injection volume, then log it in Regimen. Free — every feature unlocked for your first compound. No paywall, no trial, no credit card. 4.8 stars.
Why Track Testosterone Cypionate with Regimen?
Cypionate-specific PK curves
Regimen models testosterone cypionate's ~8-day half-life accurately. See estimated peak levels (typically 24-48 hours post-injection) and trough levels (pre-injection) based on your actual dose and frequency.
Injection frequency optimization
Compare how weekly, twice-weekly, and daily microdosing affect your blood level stability. Regimen's PK curves show the difference visually — and health metric correlation shows which frequency makes you feel best.
Daily microdosing calculator
The TRT dose calculator converts your weekly prescribed dose into daily microdose volumes for insulin syringes — the calculation that brings most TRT users to Regimen.
Blood pressure monitoring
Track blood pressure alongside your testosterone cypionate protocol. Essential for TRT monitoring.
Share and export your data
Share your protocol and blood pressure data with your TRT provider, export your full dose history, or compare progress photos side-by-side.
