Could low testosterone be holding you back?

Testosterone levels naturally decline by around 1–2 % per year after the age of 30, and studies suggest up to one in four men may be affected. Yet most remain undiagnosed and unsupported. 

Common signs include:

  • Persistent fatigue or “afternoon crashes”

  • Low mood, irritability or anxiety

  • Reduced sex drive or sexual performance

  • Difficulty building or maintaining muscle

  • Unexplained weight gain, especially around the waist

  • Brain-fog, loss of focus or motivation

  • Poor sleep quality

If several of these ring true, a simple blood test can give you answers.

A straightforward path to clarity

  1. Quick, at-home blood test – a finger-prick kit delivered to your door measures both total and free testosterone.

  2. Expert review & personalised plan – your Keltoi clinician analyses your results alongside your symptoms, lifestyle and goals to decide whether TRT—or another approach—is right for you.

  3. Ongoing care – follow-up blood tests every 3–6 months, secure messaging and video consultations ensure your treatment stays safe and effective.

Potential benefits our patients report

Every individual responds differently, but men who restore their testosterone to a healthy range often notice:

  • Higher, steadier energy throughout the day

  • Renewed sex drive and improved erectile function

  • Easier muscle gain and faster recovery from exercise

  • Sharper focus, clearer thinking and improved mood

  • Better-quality sleep and a sense of overall wellbeing

Clinical data show that structured TRT programmes can improve many of these areas within three to six months for the majority of suitable patients.

  • When prescribed appropriately and monitored, TRT is considered safe for most men with clinically low levels. We track haematology, prostate health and cardiovascular risk at every checkpoint.

  • Many men stay on therapy long-term, but treatment length depends on your underlying cause, goals and how you feel on therapy. We review this together at each appointment.

  • Testosterone therapy can suppress sperm production. If fertility is a priority we’ll discuss alternative strategies or concurrent medication to protect it.

  • Yes. Testing kits, prescriptions and follow-ups are managed remotely, with medication delivered to your door in discreet packaging.
