Today's lifestyle is working against men. Testosterone deficiency is becoming more common, affecting energy, motivation, and overall vitality.

Analysing these biomarkers collectively allows our doctors to accurately measure your testosterone levels and their availability for use in the body.

Look forward to more good days. In a study of over 3,000 men aged 40 to 79, low energy and reduced physical vigour tracked closely with lower testosterone levels.¹
Testosterone can help you get your mojo back. Of 32 symptoms studied in those same men, the three most closely linked to testosterone were all sexual ones, including sex drive.1,2
Testosterone has a bit of a reputation for building muscle and strength. When levels drop, so do lean mass, muscle size and strength.2
It's not just about muscle. Body fat starts creeping up when testosterone dips even slightly below the normal range.2




Testosterone deficiency is when your testosterone level is persistently low and you have symptoms that go with it. Some men are born with it, others develop it through age, stress, illness, physical trauma, lifestyle or environmental factors.
Men with low testosterone often report low mood, irritability, fatigue, anxiety, reduced libido or difficulty achieving an erection. Other common symptoms include brain fog, lack of motivation, low confidence, difficulty losing weight and difficulty gaining muscle. These can also be caused by stress, diet, sleep apnoea or other conditions, which is why a blood test helps: it rules hormones in or out so you know where to look next.
A blood test is the only way to know. Our initial test is a finger-prick test you take at home. If it shows low testosterone and you'd like to go further, medical guidelines require a second, more comprehensive test to confirm your level is persistently low and to give your doctor a baseline of your wider health before you start a TRT service. That one is a venous test, taken by a nurse or phlebotomist.
Yes, gradually. For most men levels drop by around 1 to 2% a year from the mid-thirties. Low testosterone is also more common in men living with obesity or certain long-term conditions.
Yes. You'll have a consultation with one of our doctors to go through your results, and they'll talk through whether treatment is suitable for you. Our doctors specialise in testosterone and are all registered with the General Medical Council.
Our blood test kits usually arrive within three working days. It may take longer over public holidays.
For the quickest turnaround, post your sample for morning collection on a working day. We'll come back to you with your results within one to three business days.
