DoseRoutine for TRT

DoseRoutine is an app for people on testosterone replacement therapy who want their injection schedule, ancillaries, injection sites and blood work in one place.

What does DoseRoutine do for TRT users?

DoseRoutine gives TRT users a weekly or twice-weekly injection schedule, mg-to-syringe-unit math, an injection site rotation map, ancillary tracking, and blood work trends for total and free testosterone, estradiol, hematocrit and PSA.

What you get

Protocol scheduling

Weekly, twice-weekly, every 3.5 days or daily subcutaneous — with reminders per injection.

Dose math

Convert weekly mg into per-shot volume and insulin-syringe units at any ester concentration.

Site rotation

Log delt, quad, ventroglute and SubQ sites and see what you have overused.

Lab trends

Chart the full male panel against dose changes instead of comparing PDFs.

Interaction checks

Every supplement you add is checked against your testosterone protocol and ancillaries.
