Science

TRT services, explained

What is a TRT service?

A TRT service is for men diagnosed with low testosterone. Working with a specialist doctor, your plan supports your testosterone towards a healthy range so you can feel your best again.

Why it matters

Low testosterone affects men differently, and without treatment, symptoms linked to low levels often persist. A plan means a considered approach, agreed with your specialist doctor and reviewed as you go.

Why choose Voy

Voy is the UK's largest TRT service provider, with UK-registered clinicians who specialise in hormone health and a clinical team on hand whenever you need them.

The hormone that's holding men back

Dr. Jeff Foster, Director Men's Health

Is this you?

The following symptoms could be a sign of low testosterone. We recommend you get tested to find out for sure.

Low sex drive
Low energy
Erectile dysfunction
Lack of focus
Depression
Weight gain
Low muscle mass
Fatigue

Prevalence

Testosterone levels have more than halved in the last 50 years.^¹

Today's lifestyle is working against men. Testosterone deficiency is becoming more common, affecting energy, motivation, and overall vitality.

DIAGNOSIS

Only 1 in 20 are diagnosed.²

Too many men are suffering from the life-altering symptoms of this under-diagnosed condition.

"Men with normal levels of testosterone have a better quality of life."

Dr. Jeff Foster, Voy Director of Men’s Health

BENEFITS

Get back to peak performance with a TRT service

For many men with low testosterone, life feels harder than it needs to. Regain your vitality and improve your quality of life, starting now.

Benefits for the mind

Better mood

Men with low testosterone are significantly more likely to be diagnosed with depression than men whose levels sit in the normal range.⁴

Increased energy

Loss of energy is one of nine symptoms found to track with lower testosterone levels. 86% of patients saw an improvement in their energy levels after 3 months.^1,5

Enjoyment of life

79% of patients saw an increase in their enjoyment of life after 6 months.⁵

Overall Satisfaction

90% of patients were satisfied with the treatment they received.⁵

Benefits for the body

Healthy testosterone levels

Testosterone is important for a range of physical, sexual and psychological functions, and symptoms tend to appear once levels drop below the normal range.^1,4

Better physical ability

Reduced physical vigour, including difficulty with vigorous activity, is significantly associated with lower testosterone^.1

Increased muscle

Muscle depends directly on testosterone. Lean mass and leg-press strength directly link to testosterone levels in health men.^2,³

Leaner body

Body fat responds too. Fat accumulation begins with only mild reductions in hormone levels.³

Increased libido

Sex drive is among the functions most closely tied to testosterone. Of 32 symptoms studied in over 3,000 men, the three most strongly associated with testosterone were all sexual ones.^1,3

Clinically proven treatment

Dr. Jeff Foster, Director of Men's Health

We’ll help you get your testosterone levels back within a normal, healthy range. Our programmes have research-backed benefits to your health and wellbeing. The results can be life-changing.

Better Mood

Look forward to more good days. In a study of over 3,000 men aged 40 to 79, low energy and reduced physical vigour tracked closely with lower testosterone levels.¹

Higher Sex Drive

Testosterone can help you get your mojo back. Of 32 symptoms studied in those same men, the three most closely linked to testosterone were all sexual ones, including sex drive.^1,2

Increased Muscle

Testosterone has a bit of a reputation for building muscle and strength. When levels drop, so do lean mass, muscle size and strength.²

Leaner Body

It's not just about muscle. Body fat starts creeping up when testosterone dips even slightly below the normal range.²

Testosterone deficiency is when your testosterone level is persistently low and you have symptoms that go with it. Some men are born with it, others develop it through age, stress, illness, physical trauma, lifestyle or environmental factors.

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 can also be caused by stress, diet, sleep apnoea or other conditions, which is why a blood test helps: it rules hormones in or out so you know where to look next.

A blood test is the only way to know. Our initial test is a finger-prick test you take at home. If it shows low testosterone and you'd like to go further, medical guidelines require a second, more comprehensive test to confirm your level is persistently low and to give your doctor a baseline of your wider health before you start a TRT service. That one is a venous test, taken by a nurse or phlebotomist.

Yes, gradually. For most men levels drop by around 1 to 2% a year from the mid-thirties. Low testosterone is also more common in men living with obesity or certain long-term conditions.

Yes. You'll have a consultation with one of our doctors to go through your results, and they'll talk through whether treatment is suitable for you. Our doctors specialise in testosterone and are all registered with the General Medical Council.

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

For the quickest turnaround, post your sample for morning collection on a working day. We'll come back to you with your results within one to three business days.
