Testosterone Replacement Therapy (TRT) for Men

Low testosterone can affect how you feel, think, and perform, often more than men realise. From low energy and reduced sex drive to changes in mood, strength, and body composition, declining testosterone levels can quietly impact daily life.

Testosterone Replacement Therapy (TRT) is a clinically approved treatment designed to restore testosterone levels in men with medically confirmed low testosterone. When prescribed appropriately, TRT can help relieve symptoms and support long-term physical and mental well-being.

At Online Men’s Clinic, testosterone replacement therapy for men is available following a medical consultation, with testing, clinician review, and discreet UK delivery.

What Is Testosterone Replacement Therapy What Is Testosterone Replacement Therapy

Testosterone Replacement Therapy is a medical treatment used to restore testosterone levels in men with clinically low testosterone, also known as male hypogonadism.

Testosterone is a key hormone responsible for male sexual function, muscle mass, bone density, energy levels, mood, and overall vitality. While testosterone levels naturally decline with age, some men experience a more significant drop that leads to persistent symptoms.

TRT works by supplementing the body with testosterone to bring levels back into a healthy range, helping to relieve symptoms and improve quality of life when low testosterone has been confirmed through blood tests.

Low Testosterone in Men

Low testosterone is more common than many men expect, particularly from mid-life onwards. UK data suggests testosterone levels decline gradually from around age 30, at an average rate of around 1% per year. While many men maintain healthy levels into older age, a significant minority develop symptoms linked to testosterone deficiency.

Low testosterone is also more common in men with:

  • Obesity or metabolic syndrome
  • Type 2 diabetes
  • Chronic illness
  • High stress or poor sleep
  • Certain medications

Despite this, many men delay seeking help, often attributing symptoms to stress or ageing rather than an underlying hormonal issue.

 

Common Symptoms of Low Testosterone

Symptoms can vary, but often include a combination of physical, sexual, and psychological changes.

Common signs of low testosterone in men include:

  • Persistent fatigue or low energy
  • Reduced sex drive (low libido)
  • Erectile dysfunction
  • Loss of muscle mass and strength
  • Increased body fat, particularly around the abdomen
  • Low mood, irritability, or reduced motivation
  • Difficulty concentrating or “brain fog”
  • Reduced beard or body hair growth

Symptoms often develop gradually, which is why low testosterone frequently goes undiagnosed.

Testosterone Replacement Therapy Options

There is no single TRT treatment that suits every man. The most appropriate option depends on your testosterone levels, symptoms, medical history, and lifestyle.

 Common TRT treatments prescribed in the UK include:

Testosterone Gel

Applied daily to the skin, testosterone gel is a popular option that provides steady hormone absorption without injections. 

Testosterone Injections

Injections may be short-acting or long-acting and are administered at set intervals. Some men prefer injections for convenience or dosing control.

Other TRT Options

Less commonly, testosterone may be prescribed in patch or capsule form, depending on suitability and clinical advice.

A UK-registered prescriber will recommend the most appropriate TRT treatment for you following assessment.

Is TRT Safe?

Testosterone replacement therapy is considered safe and effective for men with clinically confirmed low testosterone when prescribed and monitored correctly.

  • As with any prescription treatment, TRT is not suitable for everyone. This is why:
  • Blood tests are required before starting treatment
  • Ongoing monitoring is part of responsible TRT care
  • Treatment is only prescribed following a clinical review

Your safety is assessed throughout treatment, including regular monitoring of hormone levels and overall health.

How it Works

Getting started with testosterone replacement therapy online is straightforward:

  • Complete a confidential online medical consultation
  • Provide a testosterone blood test result to assess your hormone levels
  • A UK-registered prescriber reviews your information and test results
  • If suitable, a personalised TRT treatment plan is prescribed
  • Your TRT medication is delivered discreetly to your door

This process ensures that testosterone is only prescribed where clinically appropriate, in line with UK medical guidance.
