Testosterone is an androgen (male sex) hormone produced in men. It has an important role in male health.
Testosterone levels change throughout a person’s life and usually starts to decline steadily after the age of 40. Testosterone levels will also go up and down during the day, usually being higher in the morning and decreasing during the day.
If you want to check your levels, you can order a test kit from Superdrug Online Doctor. Complete a short questionnaire and place your order which can then be sent to your preferred address, or you can collect it from a Superdrug store. If your testosterone level is borderline or low a repeat test is recommended after 4 weeks and you would need to see your GP or a specialist if you wanted to start testosterone replacement therapy.
Please note: this test kit is for men only.

Ordering is quick and simple:
A testosterone test kit is a way of testing your testosterone levels without needing to visit a GP surgery. You take a pin-prick blood sample at home and then post it to a lab for testing.
The test kit comes with detailed instructions and Superdrug doctors are available to provide support and advice on your test and results.
You might want to test your testosterone levels if you’re a man above 40 or you’re getting any of the following symptoms:
Testosterone deficiency is rare and testosterone levels normally only drop 1-2% each year after the age of 40. There are other reasons why your testosterone levels might drop, including:
If you often can’t get or keep erections then you might have a condition called erectile dysfunction. A low testosterone level is one possible cause of erectile dysfunction, but it only applies to 4-9% of men who have erectile dysfunction. Many men think about boosting their testosterone to improve their sexual performance but it’s not the right choice for most people.
If you want to check your testosterone levels, you can order a testosterone test kit online, by following a few simple steps:
A testosterone test kit will check the levels of the male hormone ‘testosterone’ in your blood. This means that you’ll need to take some of your blood using a finger prick device called a lancet. You’ll then need to send your sample to our partner lab for testing.
You can take your sample easily at home in a few simple steps:
Don’t worry if you have trouble getting the blood sample on your first try, or if you need more blood to fill up the collection tube. In the box you’ll find three lancets, so you can try again with another finger.
Your results should be available in your account within 2 or 3 days of the lab receiving your sample. In the results you’ll see the level of total testosterone found in your blood, along with advice from a Superdrug doctor on what to do next.
Your results can be checked against the normal range of testosterone levels in men. If you’re a man aged between 19 and 39 years, your testosterone level should be over 12 nmol/L (nanomoles per litre). If your testosterone level is lower than 8 nmol/L it’s counted as being testosterone deficient. Between 8 and 12 nmol/L your level is described as “borderline”. Sometimes these ranges can vary slightly depending on the laboratory that processes your sample. If your result is low or borderline it is recommended you repeat the test after at least 4 weeks and see your GP for further tests to find out the cause of your borderline or low testosterone level. Depending on whether you’re having symptoms and whether you wish to have children in the future, your doctor may refer you to a specialist for a trial of treatment.
If your levels of testosterone are too low (lower than 12nmol/L), a repeat test is recommended after 4 weeks. If the second test confirms that your testosterone levels are still low, you may need to be referred to a specialist by your GP to start treatment with testosterone replacement therapy. If you have seen a specialist and are already taking testosterone replacement therapy, and have been receiving treatment for a year, then you can place an order for a repeat prescription through our service.
If a test shows that your testosterone levels are in the normal range for your age, testosterone replacement therapy isn’t recommended and you will need to look into other possible causes of your symptoms.
Other possible causes of erectile dysfunction, low sex drive, fatigue, or weight gain can include mood disorders like anxiety and depression, or stress caused by a certain situation at home or work. In some cases your doctor may advise you to modify your lifestyle to improve your symptoms, including:
No. Even though testosterone is linked to fertility, checking your testosterone levels is not a reliable way to test your fertility. A male fertility test usually includes checking other things related to the quality of your sperm like:
Sperm cells are responsible for fertilising an egg. If your sperm count drops in number, mobility, or they have the wrong shape, they’ll be less able to fertilise an egg. Male infertility can be related to a lot of different things and lifestyle changes can help improve many of them. If you think you could be infertile, you should talk to your GP. They will be able to arrange a semen analysis for you and tell you the best ways to improve your fertility.
