You’ve had the blood tests. Your testosterone is low. Your GP has confirmed it, or perhaps you’ve had private testing done. Now comes the question that thousands of men across the UK face every year: should you pursue TRT through the NHS, or go private?
It’s a question loaded with practical considerations, frustrations, and trade-offs. And the answer depends on where you live, how long you’re willing to wait, what treatment options matter to you, and what you can afford.
This guide compares both routes honestly. Not to sell you on one or the other, but to give you the information you need to make the choice that’s right for your situation.
The NHS Pathway: How It Works
In theory, the NHS pathway for testosterone replacement therapy is straightforward. In practice, many men find it anything but.
Step 1: Getting Your GP to Take It Seriously
This is where many men’s journeys stall before they’ve even begun. While awareness of male hypogonadism has improved, some GPs remain unfamiliar with the condition, dismissive of the symptoms, or reluctant to investigate. Men frequently report being told that their tiredness is “just stress,” their low mood is depression, or that declining testosterone is simply a normal part of ageing that doesn’t warrant treatment.
To be fair to GPs, the symptoms of low testosterone genuinely do overlap with many other conditions, and ruling out other causes is good medical practice. But there’s a difference between thorough investigation and dismissal, and too many men experience the latter.
If you’re struggling to be taken seriously, you can:
- Request blood tests specifically for total testosterone, free testosterone, and SHBG (sex hormone-binding globulin)
- Ensure blood is drawn in the morning (before 10am ideally), when testosterone levels are at their highest
- Ask for LH and FSH to help determine the cause of low levels
- Keep a symptom diary documenting how your symptoms affect your daily life
- Reference the NICE guideline NG161 on testosterone deficiency, which supports investigation and treatment in symptomatic men
Step 2: Referral to an Endocrinologist
If your blood tests confirm low testosterone, your GP will typically refer you to an endocrinologist (a specialist in hormone disorders). This is where things can slow down considerably.
NHS waiting times for endocrinology vary dramatically across the UK. In some areas, you might be seen within 6-8 weeks. In others, particularly in parts of England with high demand, waits of 4-6 months or longer are common. In Northern Ireland, endocrinology wait times have historically been among the longest in the UK, with some patients waiting over a year for their first appointment.
Scotland and Wales have their own NHS structures, and waiting times vary by health board. The general trend across all four nations is that specialist endocrinology appointments are not quick to obtain.
During this waiting period, you’re living with the symptoms of low testosterone: the fatigue, the low mood, the impact on your relationships and work. For many men, this wait is not just inconvenient. It’s genuinely harmful to their quality of life.
Step 3: Specialist Assessment and Treatment Initiation
Once you see the endocrinologist, they’ll typically:
- Review your blood results and may order additional tests
- Take a detailed medical history
- Examine you and potentially order imaging (MRI of the pituitary if secondary hypogonadism is suspected)
- Discuss treatment options
- Initiate TRT if appropriate
This is thorough and evidence-based care. The quality of NHS endocrinologists is generally excellent. The challenge is access, not competence.
Step 4: NHS Treatment Options
Here’s where the NHS pathway has its most notable limitations. The medications available on the NHS for TRT are typically:
Sustanon 250: A blend of four testosterone esters injected intramuscularly every 2-4 weeks. It’s the most commonly prescribed option. The main drawback is pharmacokinetic: testosterone levels peak sharply after injection and then decline, creating a “rollercoaster” effect. Many men feel great for the first week after injection, then progressively worse as levels drop before their next dose.
Nebido (testosterone undecanoate): A longer-acting injection given every 10-14 weeks. It provides more stable levels than Sustanon but involves a large-volume injection and is significantly more expensive for the NHS, meaning some areas are reluctant to prescribe it.
Testogel or Tostran (testosterone gel): Applied daily to the skin. Provides stable levels but requires daily adherence, carries transference risk, and some men find it doesn’t absorb well enough to achieve adequate levels.
What the NHS typically doesn’t offer is testosterone cypionate or enanthate for self-injection at home on a weekly or bi-weekly basis. This is the protocol many private clinicians (and increasingly, international endocrinology guidelines) consider the gold standard for stable testosterone delivery, because frequent smaller doses minimise peaks and troughs. It is available in the UK but is usually only accessible through private prescriptions.
Step 5: Ongoing Management
After initiation, ongoing TRT management may be shared between your endocrinologist and GP. Some GPs are comfortable managing TRT long-term with periodic specialist review. Others are not, and you may find yourself bouncing between services. Monitoring frequency on the NHS can sometimes be less than ideal, with some men reporting that blood tests are performed less often than guidelines recommend.
The Private Pathway: How It Works
Initial Assessment
Private clinics typically offer a faster, more streamlined process. You can usually arrange blood tests within days (either through the clinic or a private laboratory), and consultations are available within 1-2 weeks of receiving your results. The entire process from initial enquiry to starting treatment can often be completed within 2-4 weeks.
Broader Treatment Options
Private clinics have access to the full range of testosterone formulations, including testosterone cypionate and enanthate for self-injection. This allows for more personalised treatment protocols. Many private clinicians also offer adjunct therapies such as hCG (to maintain fertility and testicular function) and more detailed monitoring of markers like oestradiol and free testosterone, which aren’t always routinely measured on the NHS.
More Responsive Monitoring
Private clinics typically offer more frequent blood tests, particularly in the early stages of treatment, and faster turnaround on results. Dose adjustments can be made more quickly in response to blood work and symptom feedback. Many services, including Evernu, provide remote consultations and home blood testing kits, making ongoing management more convenient.
The Cost Question
This is the unavoidable trade-off with private care. Here’s a realistic breakdown of what private TRT might cost:
| Item | Typical Cost Range |
|---|---|
| Initial consultation | 100-250 pounds |
| Comprehensive blood panel | 100-200 pounds |
| Monthly medication (testosterone) | 30-100 pounds |
| Follow-up blood tests (every 3-6 months) | 80-150 pounds per test |
| Follow-up consultations | 50-150 pounds per visit |
| hCG (if prescribed) | 30-80 pounds per month |
Over a year, private TRT might cost between 1,000 and 3,000 pounds depending on the provider, the protocol, and how many blood tests and consultations you need. This is a significant financial commitment, and it’s important to factor it into your decision.
By comparison, NHS TRT costs only the standard prescription charge per item (currently 9.90 pounds in England, free in Scotland, Wales, and Northern Ireland). Blood tests and consultations are free.
Comparing the Two Routes
| Factor | NHS | Private |
|---|---|---|
| Time to first appointment | Weeks to months | Days to 2 weeks |
| Time to starting treatment | Months to over a year | 2-4 weeks |
| Treatment options | Usually Sustanon, Nebido, or gel | Full range including cypionate/enanthate |
| Dosing flexibility | Limited | Highly personalised |
| Monitoring frequency | Variable, sometimes infrequent | Regular, protocol-driven |
| Ongoing cost | Free or prescription charge only | 1,000-3,000 pounds per year |
| Adjunct therapies (hCG, etc.) | Rarely offered | Available if appropriate |
| Convenience | Hospital appointments, travel | Often remote consultations, home testing |
| Clinical expertise | High (NHS endocrinologists) | Variable (check credentials and regulation) |
What NICE Guidelines Say
The NICE guideline NG161 provides the framework for testosterone deficiency management in the UK. Key recommendations include:
- Testosterone deficiency should be confirmed with at least two morning blood tests
- Both symptoms and biochemical confirmation are required for diagnosis
- Reversible causes (such as obesity, medications, or pituitary disease) should be identified and addressed
- Treatment should aim to relieve symptoms and restore testosterone to the mid-normal range
- Regular monitoring of testosterone levels, haematocrit, and PSA is recommended
- Patients should be counselled about the effects on fertility before starting treatment
These guidelines apply regardless of whether you’re treated on the NHS or privately. Any responsible provider, in either sector, should be following these standards.
A Hybrid Approach
Some men find that a hybrid approach works best:
- Start privately to get diagnosed and begin treatment quickly
- Transition to the NHS once stabilised, asking their GP to take over prescribing
- Use private blood tests if NHS monitoring feels insufficient
This isn’t always straightforward. Some GPs are willing to continue a private prescription; others are not. If you’re considering this route, it’s worth having the conversation with your GP early to understand their position.
How Evernu Fits In
Evernu is a RQIA-regulated private healthcare provider offering testosterone replacement therapy to men across the UK, including England, Scotland, Wales, and Northern Ireland. We occupy the space between the NHS pathway (thorough but often slow) and the unregulated “testosterone mills” (fast but often unsafe).
Our approach includes:
- Comprehensive initial blood testing and medical assessment
- Consultation with clinicians experienced in testosterone management
- Access to the full range of treatment options, tailored to your needs
- Regular blood monitoring with clear protocols
- Ongoing clinical support and dose optimisation

We’re not the right choice for everyone. If you’re able to access timely, high-quality TRT through the NHS and you’re happy with the treatment options available, the NHS route may serve you well and save you money. But if you’re facing long waits, limited treatment options, or you want a more proactive and personalised approach, our testosterone treatment service is designed to fill that gap.
Choosing a Private Provider: Red Flags to Watch For
If you do decide to go private, choosing the right provider is critical. Not all private TRT clinics are created equal, and the rapid growth of the market has attracted some operators whose priorities are commercial rather than clinical.
Warning signs include:
- Prescribing without proper blood work: Any provider willing to prescribe testosterone based solely on symptoms, without confirmed blood test results, is cutting dangerous corners
- No regulatory registration: In the UK, healthcare providers should be registered with the appropriate regulator (CQC in England, Healthcare Inspectorate Wales, Healthcare Improvement Scotland, or RQIA in Northern Ireland)
- Minimal monitoring: If follow-up blood tests are infrequent or optional, the provider isn’t prioritising your safety
- Aggressive marketing with unrealistic promises: Claims about “reversing ageing” or “unlocking peak performance” should raise scepticism
- Pressure to purchase supplements or add-ons: Your treatment should be determined by your clinical needs, not upselling
- No qualified prescriber: Ensure you’re being assessed and prescribed by a GMC-registered doctor with relevant experience
Frequently Asked Questions
Can my GP prescribe TRT without a specialist referral?
Technically, GPs can prescribe testosterone, but most prefer to have the initial diagnosis and treatment plan established by an endocrinologist or specialist. Some GPs are comfortable initiating TRT if the diagnosis is straightforward, while others will always refer. If your GP is willing to manage your TRT, they can prescribe Sustanon, Nebido, or testosterone gel on NHS prescription. However, testosterone cypionate and enanthate typically require a private prescription as they’re not commonly stocked by NHS pharmacies.
How long are NHS endocrinology wait times?
This varies enormously depending on where you live. In some parts of England, you might wait 8-12 weeks. In others, particularly in areas with high demand or endocrinologist shortages, waits of 6-12 months are not uncommon. Northern Ireland has historically had some of the longest specialist waiting times in the UK. Scotland and Wales vary by health board. You can ask your GP practice about expected waiting times for your local area, or check NHS waiting time data for your region.
Will the NHS prescribe testosterone cypionate or enanthate?
It’s uncommon. The standard NHS TRT options are Sustanon 250, Nebido, and testosterone gels (Testogel/Tostran). Testosterone cypionate and enanthate are licensed medications in the UK but are primarily available through private prescriptions. Some NHS endocrinologists may consider them on a case-by-case basis, but this is the exception rather than the rule. If stable levels from weekly or bi-weekly self-injection are important to you, you’ll likely need to explore private options.
Can I get a private diagnosis and then transfer to the NHS?
This is possible but depends on your GP’s willingness to accept a private diagnosis and take over prescribing. Some GPs will review the private clinician’s notes and blood results and agree to continue the same prescription. Others may want to repeat tests or refer to an NHS endocrinologist before taking over. If you’re planning this approach, discuss it with your GP early. Having a private diagnosis from a reputable, regulated provider with comprehensive documentation will make the transition easier.
Is private TRT regulated in the UK?
Private healthcare providers in the UK must be registered with the appropriate regulatory body: CQC (Care Quality Commission) in England, Healthcare Inspectorate Wales, Healthcare Improvement Scotland, or RQIA (Regulation and Quality Improvement Authority) in Northern Ireland. All prescribing doctors must be registered with the GMC (General Medical Council). When choosing a private provider, check their regulatory registration and the credentials of their medical team. Regulation doesn’t guarantee perfection, but it provides a framework of accountability and minimum standards.
Your Next Step
Whether you choose the NHS or a private provider, the most important thing is that you pursue proper medical evaluation and treatment if you’re experiencing symptoms of low testosterone. Both routes have their strengths and limitations, and the right choice depends on your individual circumstances, priorities, and budget.
