Built for your routine

Everything your protocol needs. Nothing it doesn’t.

Log a shot in seconds

Amount, time and injection site in a few taps. Skip a dose when you need to, and add a note about how you feel.

Smart site rotation

Dozia highlights the injection site you used least recently, across abdomen, thighs, arms and glutes.

Dose reminders

Right on time, or 15 or 30 minutes early. Log a dose early and its reminder cancels itself.

PRO

Modelled level curves

See where you are between doses, built from your own logs and published half-lives. An estimate, never a lab value.

PRO

Supply forecasts

Know weeks ahead when a vial or pen runs low, so you can reorder before it becomes urgent.

Compound library

Semaglutide, tirzepatide, testosterone, HCG and 20+ peptides, each with its half-life and a note on how solid the data is.

Unit converter

From vial to syringe units, without the mental math.

Enter your vial amount, the bacteriostatic water you added and the dose your provider prescribed. Dozia shows exactly where to draw on a U-100 syringe.
