Getting started
Online questionnaire
Answer a few questions about your health. A blood test is always an option, but based on your answers, we can already assess whether you might be eligible for testosterone replacement therapy.
Testosterone test
Start with a simple lab test that measures your total and free testosterone levels. The results will give you a clear picture of your testosterone levels and provide specific guidance and advice on how you might increase them if necessary.
Further investigation if levels are low
If your testosterone levels are too low (total below 12 nmol/L or free below 70 pg/mL), further tests will be carried out. We will also measure your PSA and haematocrit levels to ensure you can start treatment safely.
Start your treatment
Our doctors will draw up a personalised plan including medication and lifestyle advice. The subscription covers medication, blood tests, consultations, doctor’s letters and discreet delivery. Please note: medication costs may be (partly) subject to your excess.
Monitoring
As everyone reacts differently to testosterone, we schedule an initial review after 6 weeks. Blood tests will be carried out after 6 and 12 months (included), so that your doctor can monitor your progress and optimise your treatment. You can track your own levels over time via your Fellos portal.
