Both blood tests must be completed before your consultation
You need the Initial finger-prick test and the Enhanced venous test. Your clinician needs both sets of results to diagnose and prescribe. You can still book ahead — just make sure both tests are done before your appointment date.

A full in-depth review — Unhurried time with a doctor experienced in men's hormone health — not a 10-minute slot.
A plain-English plan — What your results mean, what your options are, and what happens next — in writing.
A prescription if appropriate — If TRT is suitable, treatment and ongoing monitoring can start straight away.
Recent blood tests — Ideally taken in the morning, before 10am, when testosterone levels are highest.
Medical history — Current medications, supplements and any relevant health conditions.
TRT is an effective treatment, but it is a medicine with real trade-offs. Here is what you should weigh up before starting.
Acne, oily skin, mood changes, mild fluid retention and a raised red blood cell count (haematocrit) are the most commonly reported effects. These are monitored through regular blood tests and managed by adjusting your dose.
Testosterone replacement therapy (TRT) suppresses your body's own testosterone production and can reduce sperm count while you are on treatment. If you are planning a family, tell your clinician — fertility-preserving alternatives such as clomiphene or hCG may be more appropriate.
For most men TRT is ongoing. Stopping abruptly can cause levels to fall quickly and symptoms to return, so any change should be planned with your clinician.
TRT is only prescribed where low testosterone is clinically confirmed. It is not prescribed for muscle building or athletic performance, and some medical histories make it unsuitable.
Ongoing blood tests and reviews are part of safe treatment. If you are unable to commit to monitoring, TRT is not appropriate for you.
More detail is set out in our frequently asked questions. Your clinician will go through all of this with you before prescribing.
