Male health
Testosterone is a system, not a single number.
We measure your testosterone, the fractions actually available to your body, and the brain signals that regulate them — read together by a clinician.
Why it matters
Why one reading can mislead
Fatigue, low drive and shifting body composition are easy to pin on testosterone alone, but they are usually multifactorial. And a single total testosterone reading can mislead — much of it is bound to proteins and unavailable to your tissues.
What matters isn't just how much testosterone you have — it's how much your body can actually use.
Free testosterone, SHBG and the Free Androgen Index show the fraction your tissues can access.
Who it is for
For men who want a clear read on their hormonal health — an accurate baseline, not a guess.

From booking to plan
How it works
A straightforward journey from question to clear, clinician-reviewed answers.
- 1
Book a morning slot
Testosterone peaks between 7am and 10am — we recommend a fasting sample in that window.
- 2
One blood sample
With a blood pressure reading and a short set of context questions at the same visit.
- 3
Clinician review
Your androgens, testosterone–oestrogen balance and brain signals read together.
- 4
A baseline you can use
A plain-English explanation of what it means for you, and a reference point to measure against.

Tell me what you'd like to get out of testing, or what you've been noticing, and I'll point you to the right pathway and level. I can also explain any marker.
