Could it be low testosterone?
Low testosterone can affect many areas of your life. You may notice
Low energy and motivation
Reduced libido
Reduced morning erections
Loss of muscle mass and strength
You may be suitable for a TRT assessment if you
- are experiencing symptoms of low testosterone
- have had a low testosterone result (or want to check)
- are aged 18 or over
- are in generally good health
- want a full clinical assessment and personalised advice
These symptoms don’t necessarily mean you have low testosterone. Sleep problems, obesity, stress, medication, diabetes, thyroid disease and other conditions can cause similar symptoms. That’s why diagnosis starts with proper assessment rather than treatment alone.
- Treatment is subject to a clinical assessment to ensure it is safe and appropriate for you.

What is TRT?
Testosterone replacement therapy (TRT) is used to treat men with confirmed low testosterone and related symptoms. It works by replacing testosterone to help restore hormone levels and improve symptoms such as low energy, reduced libido, low mood and loss of strength.

Start with a simple testosterone check
Initial Testosterone Check — £89
Not sure whether your testosterone levels may be contributing to your symptoms?
Our finger-prick testosterone test provides a convenient first check and can help determine whether further investigation may be appropriate.
Initial finger-prick testosterone check
- Quick and convenient
- Small finger-prick blood sample
- Testosterone screening
- Suitable as an initial check
- Results reviewed by our clinical team
Best for: men who are curious about their testosterone level or want an initial screening test before deciding whether to investigate further.
Prescription treatment is only supplied where clinically appropriate, following assessment by a qualified prescriber.
A screening result alone does not diagnose testosterone deficiency. If your results or symptoms suggest further assessment is appropriate, we may recommend comprehensive venous blood testing and a clinical consultation.
Comprehensive testosterone assessment
If you are experiencing symptoms of testosterone deficiency, have had a low or borderline testosterone result, or are considering testosterone treatment, a more detailed assessment is required.
Our comprehensive venous blood test looks beyond testosterone alone and helps your clinician understand your wider hormonal and metabolic health.
Full venous blood draw
Your assessment may include:
Hormonal markers
- Total testosterone
- SHBG
- Calculated free testosterone
- LH
- FSH
- Prolactin
Health and safety markers
- Full blood count and haematocrit
- Liver function
- Kidney function
- PSA where clinically appropriate
Metabolic health
- HbA1c
- Cholesterol and lipid profile
Your clinician will determine the appropriate investigations based on your age, symptoms, medical history and treatment goals.
Best for: men with symptoms, abnormal screening results, patients considering TRT, and people transferring their care from another provider.
Ongoing support
Personalised care throughout your journey
More than a one-off consultation. We stay involved as your needs change.
- Regular clinical reviews
- Progress and symptom monitoring
- Digital check-ins
Depending on your individual treatment plan, monitoring may include:
- testosterone levels
- symptom response
- haematocrit/full blood count
- PSA where clinically appropriate
- blood pressure
- weight/body composition
- treatment side effects
- cardiovascular risk factors
Diagnosis and treatment should be based on symptoms, appropriate blood testing and clinical assessment, in line with British Society for Sexual Medicine guidance on testosterone deficiency

Testosterone Replacement Therapy (TRT): What It Is, Benefits, Risks and How It Works
Testosterone replacement therapy, commonly known as TRT, is a medical treatment used in men who have symptoms of testosterone deficiency alongside appropriately
Frequently asked questions
Here are detailed answers to the frequently asked questions about Testosterone Replacement Therapy (TRT)
What is TRT?
Testosterone Replacement Therapy (TRT) is a medical treatment for men who have clinically confirmed low testosterone (hypogonadism). It aims to restore testosterone levels to a normal range, which may help improve symptoms such as low energy, reduced libido, low mood, and loss of muscle mass.
What are the symptoms of low testosterone?
Symptoms can include constant tiredness even after sleep, a noticeable decrease in sex drive, weaker or fewer erections, low mood or irritability, loss of muscle mass, increased body fat, and poor concentration or brain fog.
How is low testosterone diagnosed?
We base diagnosis on your symptoms, medical history, and blood results, not symptoms alone. We may start with a simple testosterone screening test, but men progressing towards treatment usually require comprehensive venous blood testing and clinical review.
What does the comprehensive blood test check?
A comprehensive assessment may include total testosterone, SHBG, calculated free testosterone, LH, FSH, prolactin, and broader health markers such as a full blood count, liver function, kidney function, lipids, HbA1c, and PSA, where clinically appropriate. The exact tests will depend on your age, symptoms and medical history.
Why might I need more than one blood test?
Testosterone levels naturally fluctuate and can be affected by factors such as sleep, illness and the time of day. A low or borderline result may therefore need confirmation with a follow-up morning blood test before treatment is considered.
What treatments are available for low testosterone?
Where TRT is clinically appropriate, testosterone can be prescribed in different formulations, including injections and topical preparations. The most appropriate treatment depends on your clinical assessment, preferences, response and monitoring requirements.
Will TRT affect my fertility?
It can. Testosterone therapy can suppress the body’s own testosterone production and reduce sperm production. If you are trying for a baby now or may want children in the future, this should be discussed before treatment begins.
Can TRT help with erectile dysfunction?
If erectile dysfunction is partly related to confirmed testosterone deficiency, restoring testosterone to an appropriate range may help some men. However, ED has many possible causes, so testosterone treatment will not necessarily resolve it and other assessment or treatment may still be required.
Who is suitable for TRT?
TRT is suitable for adult men (18+) who have both symptoms of low testosterone and biochemically confirmed low levels on two separate blood tests. It is not suitable for men with certain conditions, such as severe heart failure, prostate or male breast cancer, or those with excessively thick blood (high haematocrit).
What are the benefits of TRT?
For men with confirmed hypogonadism, TRT is associated with significant improvements in libido, erectile function, lean body mass, bone mineral density, and overall quality of life. It can also improve mood, energy levels, and metabolic risk factors.
Are there any risks or side effects?
Common side effects include acne, mood swings, fluid retention, and gynecomastia (breast tissue growth), though these are generally manageable. More serious risks require monitoring, including potential effects on prostate health and an increase in red blood cell production (which can thicken the blood).
Do I need to attend in person?
Your clinician will explain whether a remote or in-person appointment is appropriate. Further blood tests or an in-person review may be needed before treatment is considered.
How do I know if I might have low testosterone?
Symptoms can include reduced libido, fewer morning erections, erectile dysfunction, low energy, reduced strength, changes in body composition and low mood. These symptoms are not specific to testosterone deficiency, so diagnosis requires appropriate blood testing alongside a clinical assessment.
How long does TRT take to work?
Response varies between individuals. Some men notice changes in symptoms such as libido, energy or wellbeing within the first few weeks, while other effects may take several months. Assess treatment over time rather than judging it after only a few days.
What monitoring will I need while taking TRT?
TRT requires ongoing clinical review and blood monitoring. Depending on your circumstances, this may include testosterone levels, full blood count and haematocrit, PSA where appropriate, blood pressure and other relevant health markers. Treatment may be adjusted according to your results, symptoms and any side effects.
I am already receiving TRT elsewhere. Can I transfer to Puri Pharmacy?
Yes. If you are already receiving TRT, we can review your current treatment, previous blood results and clinical history to determine whether ongoing care through Puri Pharmacy is appropriate. We may need additional blood testing or an assessment before prescribing.
