About flexible subscriptions

How does a subscription work?

When you purchase this test subscription plan, we will automatically send you another test kit in a few months. Don't worry - you have full control over when this will be, and you can change/cancel it anytime.

When you first purchase this test, you can choose your subscription options in the checkout. We do this, because we recommend taking multiple tests over time to track how your biomarkers change. You'll be charged per test kit (rather than monthly, for example).

Why subscribe to multiple tests?

One test will show you what areas you need to focus on, continued testing will help you learn how your training, diet and lifestyle is impacting your health.

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what's tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.

Biomarkers are specific compounds we can detect in your blood sample that reflect different things about your health. Your test will tell you your levels for each of the above biomarkers, and whether they are in a normal range.

Question

What is a blood test for testosterone?

Our testosterone blood test checks your Total Testosterone levels. This is the total amount of available testosterone in your blood. The test only requires a small amount of blood and is analysed at an NHS lab and reviewed by our medical experts.

How do testosterone blood tests work?

You can check your testosterone levels accurately at home using our finger-prick blood test kit. We also offer clinic services, where a healthcare professional draws blood from your vein. The kit includes everything you need to quickly and easily collect a small blood sample and send it to our NHS labs for analysis.

Our doctors will review your results and provide a comment to help you better understand your levels and what you can do to improve (you can opt out of this during checkout if you’d prefer).

What is a normal testosterone blood level for men?

Healthy testosterone levels for men are between 8.6 and 29 nmol/L, however, this will vary depending on various factors including age, gender, weight, and even what time you collect your blood sample. We recommend you collect your blood sample between 8-10am (or up to 3 hours after waking up).

We analysed over 4,000 testosterone results and found the average testosterone level for men in the UK is 18nmol/L. Average levels for men by age are:

  • 18-30: 18 nmol/L
  • 31-40: 18.3 nmol/L
  • 41-50: 17.4 nmol/L
  • 51-60: 17.2 nmol/L
  • 61+: 13.6 noml/L

18% of male Forth customers who tested their testosterone levels had levels outside of the healthy range. You can find your testosterone levels and what your healthy range is using this testosterone blood test.

Testosterone is also important for women, but the healthy range is significantly lower than for men, ranging between 0.3 and 1.7nmol/L.

What are low testosterone symptoms?

Symptoms of low testosterone in men include fatigue, decreased libido (sex drive), erectile dysfunction, loss of muscle mass, decreased bone density, increased body fat, mood changes, decreased facial and body hair growth, decreased semen volume and hot flashes.

There are several ways to increase your testosterone naturally. These include: getting plenty of good quality sleep regularly, HIIT workouts and weight training, increasing your vitamin D levels (consider taking a supplement), minimising your cortisol and stress levels, and eating a healthy balance of protein, carbs, and fats.

In the event of unusually low levels of testosterone, you can also consult with your doctor for hormone treatment options.

Frequently asked questions

This is what our customers ask us most about this test. For more information, try our help centre.

What causes low testosterone?

Low testosterone can happen naturally, as levels start to slowly decline in men from their early 30s. But, other factors can cause testosterone levels to drop, such as overtraining, stress, medication and lifestyle choices such as lack of exercise, poor diet, and alcohol consumption.

Low testosterone, also known as hypogonadism, comes with various symptoms, including:

  • Decreased libido
  • Erectile dysfunction
  • Fatigue
  • Depression and irritability
  • Reduced muscle mass:
  • Increased body fat
  • Decreased bone mass
  • Hair loss
  • Hot flashes
  • Sleep disturbances

What causes high testosterone?

In men, high testosterone levels can be caused by testosterone replacement therapy (TRT) or a number of health conditions including: androgen resistance, congenital adrenal hyperplasia, and testicular cancer.

In women, high levels of testosterone can result in irregular or absent periods, frontal balding, acne, more than average body hair, increased muscle mass, and a deeper voice. This can be caused by a number of health conditions including polycystic ovary syndrome (PCOS).

We advise consulting with your GP if your results are high so this can be investigated further.

Does exercise increase testosterone levels?

Exercise can significantly impact testosterone levels in both men and women. In men, regular exercise, especially resistance training, can lead to a temporary increase in testosterone levels. This is due to the release of hormones that stimulate testosterone production, such as growth hormone and insulin-like growth factor 1 (IGF-1).

However, the effects of exercise on testosterone levels are more complex in women. While regular exercise can also lead to a temporary increase in testosterone levels, these increases tend to be smaller and less sustained than in men. This is because women’s bodies produce lower levels of testosterone naturally and are less responsive to the hormonal signals that stimulate testosterone production.

The type of exercise also plays a role in how testosterone levels are affected. Resistance training, which involves lifting weights or using resistance bands, is generally more effective at increasing testosterone levels than cardio exercise. This is because resistance training causes muscle damage that the body repairs, leading to an increase in the production of testosterone and other hormones that promote muscle growth.

Whilst exercise can have a positive effect on your testosterone levels, repeat overtraining and not enough recovery time can cause testosterone levels to drop and cortisol levels (the “stress hormone”) to rise. It’s important to ensure that you schedule adequate recovery into your training plan to give your body a chance to both absorb your training and replenish your biomarkers.

Can I increase my testosterone levels naturally?

If your testosterone levels are low and you want to increase them without TRT, you can.

Here are some natural ways to increase testosterone levels:

Exercise regularly: Strength training and cardio are both beneficial for testosterone production. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.

Get enough sleep: Sleep is essential for testosterone production. Aim for 7-8 hours of quality sleep each night.

Maintain a healthy weight: Excess body fat can lead to lower testosterone levels. Aim for a healthy body weight for your height and age.

Eat a healthy diet: A diet rich in protein, vegetables, and fruits can help to increase testosterone levels. Avoid processed foods, sugary drinks, and excessive amounts of saturated and unhealthy fats.

Reduce stress: Chronic stress can suppress testosterone production. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.

Consider supplements: Some supplements, such as vitamin D and zinc, may help to increase testosterone levels. Talk to your doctor before taking any supplements.

Remember that these are just general guidelines, and what works for one person may not work for another. It is always a good idea to talk to your doctor to get personalized advice on how to maintain healthy testosterone levels.

Can I use this test when on TRT?

Testosterone replacement therapy (TRT) will cause you to have synthetic hormone levels. The Testosterone test will be able to show the levels of this hormone in your body, but it is worth remembering that this will not show you how your body is performing at producing testosterone. High doses of TRT can cause your levels to go above the detectable levels of the analysis technology.

How can I increase my testosterone levels?

There are a number of ways to increase your testosterone naturally. These include: getting plenty of good quality sleep on a regular basis, HIIT workouts and weight training, increasing your vitamin D levels (consider taking a supplement), minimising your cortisol and stress levels, and eating a healthy balance of protein, carbs, and fats.

In the event of unusually low levels of testosterone, you can also consult with your doctor for treatment options.

Is this test suitable for women?

Yes, This test is suitable for both men and women.

Whilst testosterone is usually identified as a “male hormone”, premenopausal women produce both oestrogen and testosterone. You can learn more about the role testosterone plays in the female body in our blog.

How soon will the test arrive?

If you order your test before midday on a Monday to Friday then your kit will be dispatched
the same day.

All our kits are sent out via Royal Mail first class post, so it should be with you within 1-2
working days.

Can I have someone take my blood for me?

Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.

A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.

The nurse will give you the blood sample to return to us using the pre-paid envelope provided.

Does a doctor review my results?
