The truth about testosterone supplements

Most over-the-counter boosters show marginal or inconsistent results. They may support general wellbeing, but they are unlikely to restore testosterone to a healthy physiological range, and none are doctor-monitored or prescribed based on your actual levels.

What is TRT?

TRT is used to treat men with low testosterone levels, which can cause a range of life-debilitating symptoms. It works by supplementing the hormone, helping restore you to optimal body functions and overall well-being.

Could it be you?

The following symptoms could be a sign of low testosterone.

  • Low sex drive
  • Low energy
  • Erectile dysfunction
  • Lack of focus
  • Depression
  • Weight gain
  • Low muscle mass
  • Fatigue
What is testosterone and why does it matter?

Testosterone is the predominantly male sex hormone which is responsible for male development through puberty. It also has important roles throughout the body and affects physical, mental and behavioural factors.

What are the benefits of TRT?

There are a long list of benefits from using TRT including increased energy, mood, muscle mass, strength and cognition, as well as better sleep quality, more assertiveness and improved bone density.

What are considered normal vs low testosterone levels?

Low testosterone is a combination of testosterone levels and symptoms. When men get symptoms it is very individual and related to genetic factors such as androgen receptor type and other biomarkers. Guidelines state that a healthy testosterone level sits somewhere between 15-30 nmol/L.

Is TRT safe?

Undergoing testosterone replacement therapy is completely safe if you’re treated by a specialist doctor who regularly monitors your testosterone levels along with any side effects. At VOY we regularly monitor your blood results and symptoms to identify any rare issues you may be having so that we can manage them early.

Are there any side effects?

As with all medications, some people may experience side effects - however, they’re easily controlled and generally avoided with sensible doses and regular monitoring. Some possible minor side effects include fluid retention, acne, and hair loss. More severe potential side effects include gynaecomastia (the growth of breast tissue), worsening of existing sleep apnea, increased cholesterol levels, decreased sperm count, and an increased number of red blood cells which may increase your risk of blood clots or a worsening of benign prostatic hyperplasia (enlarged prostate). However, these conditions are rare and can be mostly avoided or controlled through regular monitoring and other medications.

In order to keep side effects to a minimum you’ll check in to monitor your testosterone levels and any potential side effects. If you have any concerns or questions, get in touch with our clinicians - it’s free!

Is TRT legal to purchase?

It is legal to purchase TRT online in the UK when buying through a private clinic such as VOY.

Aid
Treatment

How does it work?

TRT can be administered through various methods, including injections, tablets and creams. Our expert, best-in-class TRT clinicians will advise based on your needs and preferences.

How do the treatments work?

Everyone's medical history is different so our doctor will prescribe a medication that works specifically for you. Successful hormone therapy involves getting just the right dose by the right delivery method for your individual needs. Testosterone replacement therapy involves taking prescribed testosterone medication in the form of injections, pills and creams.
‍
Testosterone injections are the most common form of medication as they are convenient and most effective for the majority of men.

How do I start 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.

If both tests show that you have low T levels, you’ll discuss suitable treatment options with one of our doctors and during an in-depth consultation before starting treatment.

How long will it take to see results?

The time taken to see results depends on your individual response and the medication you are taking. Most men start to see benefits within the first 6 weeks to 3 months. We will support you all the way with advice and regular blood testing to ensure any changes that are required to your protocol are made early in your journey.

Do I need to take TRT forever?

We usually recommend a 3-6 month trial of treatment, after which your doctor may recommend stopping treatment if you continue having symptoms despite optimal hormone levels. At VOY, we recommend the best treatments that maintain your testicular function and make stopping your treatment easier, if required for any reason in the future.

FAQ

Testosterone Replacement Therapy

Jeff
Curated by Dr. Jeff Foster, Testosterone Medical Expert
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.
