Why supplements don't work

Most men trying to fix low testosterone start with supplements. Here's why they end up here instead.

75% of testosterone supplements have no evidence they work¹
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.

TRT doesn't "boost" testosterone. It restores it.

That's why 90% of Voy patients see results within 3 months, where supplements couldn't deliver.

A 360° view of your testosterone

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

Total TRT
Total testosterone
This is the total amount of testosterone found in the blood. Some of it is attached to proteins, such as Sex-Hormone Binding Globulin.
Free TRT
Free testosterone
This is the testosterone which is not attached to any proteins so it’s free to be used by the body’s cells. The more you have of it, the better.
SHBG
SHBG
This protein regulates hormone levels by binding to sex hormones, including testosterone. When your SHBG levels are high, your body has less free testosterone available.
Protein
Albumin
Another protein produced in the liver which binds to testosterone, inhibiting its ability to be used by the body’s cells.

Testosterone Replacement Therapy

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.
