## What is Vialora?
Vialora is a journal for people following clinician-prescribed testosterone replacement therapy who want an accurate, organized record without being told what to take or when to take it. Each entry captures the dose administered, medication label, route, date, time, and site, so your history stays clear over time.
Lab results sit alongside your injection log, with room for total and free testosterone, estradiol, hematocrit, and PSA next to the reference range from your own laboratory. With Vialora Pro, you can follow charts that compare your recorded dose, labs, and well-being, and generate clinician-ready reports.
