Education, not medical advice
The guides, calculators and other content on trtracker.com are general information about testosterone and testosterone replacement therapy (TRT). They are not medical advice and do not replace an assessment by a qualified clinician who knows your health history.
Decisions about your treatment
Never start, stop or change a medication, dose or injection schedule based on this website or the TRTracker app. Talk to your prescribing clinician first. If you notice new or worsening symptoms, contact your care team.
Tools and estimates
Calculators and charts on this site and in the app show estimates based on the numbers you enter and published averages. Real levels vary from person to person. An estimate is not a lab result and is not a reason to change your treatment.
The TRTracker app
TRTracker is a personal record-keeping app. It is not a medical device, and it does not diagnose, treat or prevent any condition.
Emergencies
If you think you may have a medical emergency, call 911 or your local emergency number straight away.
