Dr. Moisey is our resident endocrinology lead at One Day Tests. He oversees the programme from the clinical perspective and works alongside our laboratory and pharmacy to help you feel your best.
Here he explains what the programme involves and how you can get started.
All you need are two tests to confirm low testosterone and your treatment can begin.
Answer 10 quick questions to check if you may have low testosterone
We offer testosterone replacement therapy (TRT) programmes in the UK to help men experiencing the effects of low testosterone.
Symptoms such as tiredness, reduced muscle mass, low libido, and difficulties with focus or mood can impact daily life. Through accurate blood testing, medical guidance and medication, our TRT programmes provide a safe and effective way to restore hormone balance.
With treatment, many men notice improved energy levels, better strength, and greater mental clarity, supporting a healthier and more confident lifestyle.
Starting a TRT programme with One Day Tests also means taking steps to protect long-term health. Low testosterone has been linked to reduced bone density, anaemia, and metabolic changes that can affect heart health. By working with our specialists, you’ll receive a structured treatment plan designed around your results, ensuring ongoing monitoring and personalised care.
Our service is focused on evidence-based treatment, giving you confidence in both your wellbeing today and your future health.
Our approach is led by in-house consultant endocrinologists, GPs and Pharmacists. It is designed to be safe and effective.
We believe in predictable and transparent pricing, so that you can concentrate on getting your hormones sorted and not worry about unexpected costs.
We also believe in keeping those costs down as much as possible for you, and as we have all of the services in-house, including a state-of-the-art laboratory, we can keep them down. The team at One Day Tests is proud to offer the most cost effective TRT programme, supported by world class experts.
You are in safe hands.
TAKE YOUR INITIAL ELIGIBILITY TEST
Start with a simple eligibility testosterone test to check whether your levels may be low (i.e. less than 12 nmol/L ).
You can do this at home or at one of our 35+ nationwide clinics.
CONFIRM YOUR LOW RESULT
The second test needs to be done at one of our clinics, 2-4 weeks after the first test and includes 40+ biomarkers to confirm your low testosterone level and rule out any underlying conditions.
We will send you a special discount code to purchase this test for £69, discounted from £174!

A subcutaneous injection is an injection into the fatty layer just below the surface of the skin.
Some people find it less painful than an intramuscular (IM) injection and is good when the volume of medication that needs to be injected is relatively small.
An SC injection is usually administered under the skin of the abdomen, but it can be given under the skin of the thigh or buttocks too. We generally recommend the abdomen as an easy site to reach.
SC injections are generally also easier to perform and don’t carry the risk of entering a blood vessel which occasionally occurs with IM injections.
You can find the step-by-step guide here for the administration of subcutaneous injections.
An intramuscular injection is an injection into one of the big muscles of the body. Because muscles have a rich blood supply, an IM injection allows testosterone to get into your system quickly and effectively.
IM injections are usually delivered into the thigh, buttocks or upper arm although we generally recommend using the thigh as this is easiest to reach.
You can find the step-by-step guide here on how to administer intramuscular injections.
Yes, when prescribed and monitored properly TRT is a safe treatment.
In fact there is an increasing evidence base showing the health benefits of TRT in men with TD.
To ensure that it is safe you will need regular blood tests and review appointments.
These are included in the price of your subscription.
Yes, but only via a prescription from an appropriately qualified medical professional.
Yes, testosterone levels can often be increased by weight loss, increased exercise, reduced intake of alcohol and recreational drugs such as cannabis, or reduced use of prescription medication such as opioids.
UK guidelines advise that TD should be confirmed by two separate blood tests as hormone levels fluctuate throughout the day and from day to day.
The second blood test also screens for other hormonal issues, helps to assess for cardiovascular risk and ensures that it is safe for you to use TRT should you need it.
This just depends on your personal preference. Both methods are effective at restoring testosterone levels.
Yes, but the symptoms of TD that you experienced before starting treatment may return.
We monitor your total testosterone level and full blood count every three months to ensure your dosage is correct.
As with any medication, there are potential side effects to TRT but these are minimised by safe prescribing practices and regular monitoring.
Mild side effects include fluid retention, acne, excess body hair growth, and increased urination.
Some men may experience gynaecomastia (development of breast tissue) and reduction in testicular size.
Men who wish to have children should not use TRT as it can reduce fertility.
TRT can also cause an increased number of red blood cells which can make the blood more ‘sticky’ which is a risk for blood clots and strokes.
It is for these reasons that TRT should be closely monitored.
The aim of TRT is to restore testosterone levels to the normal physiological range.
For men who have been suffering with TD this will usually improve motivation and will allow them to train more effectively which, in turn, will improve muscle bulk.
The aim of TRT is not the same as the use of ‘anabolic steroids’ when testosterone treatments are abused to achieve ‘supraphysiological’ (very high) levels of blood testosterone. This practice is unsafe.
No, TRT is prohibited for professional athletes.
Testosterone can be given in a number of different ways.
At One Day Tests we offer three options that can all be self-administered.
These include a gel applied to the skin, and two injectable options (Cypionate and Sustanon), one given subcutaneously and the other given intramuscularly.
There are two types of injections available for your TRT programme. These are split per product.
When you sign up for a subscription you can choose. If you would like to change at a later date, or during your consultation - no problem, our pharmacists can move you onto a different option.
Subcutaneous injections go into fatty tissue under the skin for slow absorption. It is a shorter needle.
These are applied to the abdomen (belly fat, avoiding the navel area), or outer middle thigh.
It can also be applied to the outer upper arm.
Intramuscular shots target deep muscle tissue for faster absorption (this is usually good for larger doses), requiring longer needles.
This is a more difficult injection to make, so requires some practice.
For TRT intramuscular injections, the best sites are the glutes (upper outer quadrant of the buttock) or the thigh (vastus lateralis muscle). This provides the easily accessible large muscle mass.

Incorporating regular exercise and physical into your TRT programme significantly enhances overall health as well as treatment results.

Testosterone deficiency (TD) is an increasingly common problem. Estimates vary as to its prevalence but some studies estimate up to 40% of older men are affected, with rates of testosterone deficiency tending to be higher in men who suffer from other medical problems such as obesity or Type 2 Diabetes. TD is often not recognised as men are sometimes reluctant to complain of the symptoms, and clinicians often do not consider it as a diagnosis.
TD can cause symptoms of erectile dysfunction, low libido, fatigue, low mood and loss of muscle bulk. You can check to see if you may have symptoms of low testosterone using a simple questionnaire.
TD can be screened for with a simple finger prick blood test. If the initial test shows low testosterone levels then more detailed follow up blood tests will help to determine whether you might benefit from treatment.
TD can be treated in a number of ways. At One Day Tests we offer topical options in the form of a gel, or injectable options. Your need for treatment, and the option that might suit you best, can be discussed with one of our clinicians who are trained to deliver TRT.
Our service includes all follow up blood tests and review appointments to ensure that your TRT is safe and effective.
