REAL PATIENTS. REAL IMPACT.
Key symptoms: I was experiencing certain symptoms for around 12 months such as loss of concentration, tiredness all the time, and low libido.
Motivation to treat: So my wife said to me one day, are we ever going to have sex again?
Testosterone improvement: My most recent blood test with Numan was 13. I think my first ever one back in October was 8. So massive, massive transformation.
Symptom improvement: I began to feel the benefits of the treatment after about 4 or 5 months. It was just like a light switch. I had more energy, I was more focused, and just had a general sense of wellbeing.
TRT: Clinically proven to raise testosterone levels
Millions of men experience low testosterone, but there's an effective solution: TRT. Numan offers treatments to help you feel and perform at your best.
How common is Low-T?
Low testosterone affects 1 in 4 men over 30, and up to 40% of men over 45.¹ It’s more common than you might think, yet 90% of men in the UK go untreated.¹
What is TRT?
Testosterone replacement therapy (TRT) is a treatment that works by supplementing your body with testosterone to restore healthy testosterone levels, enhancing energy, mood, and strength, while boosting sex drive and overall wellbeing.²
Am I eligible for TRT?
Starting TRT begins with a blood test to check your hormone levels. If you have low testosterone, our experts will create you a personalised treatment plan, typically using pills, gels or injections.³

Even before birth, your testes start producing small amounts of testosterone. Levels increase throughout childhood and peak significantly during adolescence. By your early 20s, testosterone levels reach their highest point.
For adult men, a normal testosterone level ranges from 12 to 29 nmol/L.
These values do not account for age-related decline or individual symptoms, which your doctor will consider when interpreting your levels.
If your testosterone levels are less than 12 nmol/L and you have symptoms, you may benefit from testosterone replacement therapy (TRT) or alternative testosterone-boosting medications.
A 2022 study examined testosterone levels in 1,486 men aged 20 to 44. They determined normal testosterone levels for each age bracket by using the middle third of the data.
