"Just to make it clear, I don’t get paid for you to have a blood test. I’m here because whether your testosterone is low or not there’s a positive outcome on the horizon, let me explain. It’s important to find out where you’re at, whether low or not, this isn’t discussed enough.

Let’s say your levels come back fine, that’s great, perhaps the lifestyle still needs a bit of work, diet tidied up, more sleep etc. But with a reading of where you are now, you can check in periodically to see how you fluctuate in coming years. Even if you feel OK and fine now, for the sake of a finger prick, you can have valuable data for the following years to compare to."

What is Testosterone Deficiency (TD)?

Low testosterone is a common condition that men can be born with or develop due to age, stress, disease, physical trauma, an unhealthy lifestyle or environmental factors.

What are the key symptoms of TD?

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 symptoms may also be caused by stress, diet, sleep apnoea or other medical conditions. Our blood test helps rule out hormones so you can find the root cause.

How do you test for TD?

Blood testing is the only way to know for sure if you have a testosterone deficiency. Our Initial Testosterone Blood Test (a simple finger-prick test) can be taken at home. If the results show that you have low testosterone and you’d like to start testosterone replacement therapy, medical guidelines require you to take a second, more comprehensive blood test first to confirm your testosterone level is persistently low and to get a baseline measure of your core health before you start TRT. This one is a venous test which has to be administered by a nurse or phlebotomist.

How common is TD?

Research has confirmed that testosterone counts in men are significantly lower than they were just a few decades ago. One in four men over the age of 30 may have abnormally low testosterone levels according to scientific studies.¹

Around the age of 30 testosterone levels naturally begin to decline, but it’s usually a very gradual process. For most men, testosterone levels drop between one to two percent each year from the age of 35. Free testosterone levels also drop considerably as men age, making TD even more common. An increase in obesity, hormone-disrupting environmental chemicals, and anabolic steroid use is also making testosterone deficiency in younger men more prevalent than ever.

Will I be able to talk to a licensed doctor?

Yes, you’ll have a consultation with one of our doctors to discuss your test results and they can provide a personalised treatment plan tailored to your needs. Our doctors specialise in TRT for men and are all registered with the General Medical Council.

How do these blood tests lead to treatment?

Our initial blood test will establish whether you have a testosterone deficiency. If the first test shows that you have low testosterone you’ll need to take our second, more comprehensive blood test if you’d like to start TRT - this is to confirm you do indeed have persistently low testosterone and to get a baseline measure of your core health before you start TRT.

How soon will the test arrive?

Our blood test kits usually arrive within three working days. It may take longer over public holidays.

When will I get my results?

We’ll get in touch to give you your results within two to three business days.
