Check the clinical provider, diagnosis, full costs, monitoring and transfer arrangements before choosing a UK TRT clinic.
Medically reviewed by Peter Grice, Clinical Lead. Review confirmed 9 October 2026.
About this guide: Written by the Heracles editorial team. Sources and service prices checked on 9 October 2026. General information, not an individual diagnosis or prescribing recommendation.
Choose a clinic that can explain its diagnosis, give you the full cost, discuss alternatives and continue monitoring after the first prescription. The best choice depends on your medical history, preferred appointment format, practical access and budget. Fast approval, a low headline fee or a star rating does not answer those questions.
Heracles is a private provider and publishes this checklist. Apply it to Heracles and to any other service you are considering. Use our dated pricing comparison for fees and our NHS and private access guide for the routes into care.
Ask for the legal name of the clinical provider, the prescriber’s name and registration, and the dispensing pharmacy. These may be separate organisations. Check the relevant healthcare regulator for the service and location; CQC covers England, while the devolved nations have different regulators. Registration is a useful check, not proof that one treatment protocol is appropriate for you.
For a doctor, use the GMC register to check registration and licence status. If another professional prescribes, ask which professional register applies. Heracles is operated by THP Health Ltd; its CQC entry and team page provide places to begin checking.
| Area | Question to ask | What a clear answer should explain |
|---|---|---|
| Diagnosis | How will you confirm low testosterone? | Sample timing, repeat confirmation and how symptoms and history affect interpretation. |
| Underlying cause | What happens after an abnormal result? | How further testing or referral is decided and what happens if TRT is unsuitable. |
| Fertility | How do plans for children change the options? | A discussion before prescribing, including the effects of testosterone replacement on sperm production. |
| Treatment choice | Why is this formulation being proposed? | Alternatives, practical use, risks and any off-label or unlicensed use. |
| Monitoring | Which tests and doctor reviews are included? | A written schedule, collection arrangements and extra charges. |
| Safety | Who reviews abnormal results and side effects? | A responsible clinician and an escalation route. |
| Cost | What will my first year and next year cost? | Diagnosis, recurring treatment, testing, reviews, supplies, delivery and additional care. |
| Contract | What is the minimum commitment? | Billing, cancellation, refunds and the distinction between ending payment and changing treatment. |
| Continuity | What happens if I transfer or supply is interrupted? | Access to records, prescription information and a planned handover. |
Clinical guidance combines symptoms with consistently low testosterone and evaluation of the cause. A provider should be prepared to explain why TRT is unsuitable or why more investigation is needed. A promise of treatment based on a quiz, one screening result or a particular age is a reason to ask further questions. Endocrine Society guidance.
Also ask what happens if symptoms persist despite treatment. Care should include review of benefit and adverse effects, rather than automatic prescription renewal because a laboratory value changed. The TRT treatment guide explains monitoring and treatment limitations in more detail.
An online service can make consultations and routine follow-up easier to arrange. An in-person service can provide examination and face-to-face training where needed. Neither format is sufficient by itself: choose a provider that can arrange additional examination or referral when your assessment requires it. Ask where blood samples are collected and who can answer clinical questions between appointments.
Ask every clinic for a quote covering the same prescribed formulation and follow-up needs. An itemised membership may exclude medication and testing. A subscription may include scheduled tests but exclude extra investigations, nurse home visits or additional medicines. Compare those terms before deciding which package suits your budget.
Keep the written quote. Note its date, what is included, what can change and when you can cancel. Do not budget on receiving NHS monitoring or shared care unless your NHS GP has agreed to the arrangement.
Customer reviews can help you investigate communication, delivery and appointment experience. They cannot establish whether you personally meet diagnostic criteria or whether a protocol is safe for you. Ask the clinic how it handles abnormal results, missed tests, supply problems and patients who do not benefit.
Contact the receiving clinician before changing or stopping treatment. Ask what records are required, whether it can support your formulation, how recent your monitoring must be and what the transfer costs. Have your original diagnostic results, current prescription, treatment schedule and recent reports ready. A receiving prescriber may require further assessment or recommend a change; continuation is not guaranteed.
Heracles accepts transfer enquiries subject to clinical review and asks for the current prescription, schedule and recent blood results. Agree a handover that addresses the next prescription and monitoring responsibility with both services. Cancelling a subscription is not a medical plan for stopping TRT.
Heracles provides a private assessment pathway, with Testogel plans starting at £90/month and injectable plans at £130/month if appropriate. The initial £29.99 test and £129.99 fuller panel are separate from the treatment subscription. hCG is additional and a three-month minimum applies. Confirm any further diagnostic testing and your full quote before deciding.
The published plan includes medication, applicable supplies and scheduled monitoring and reviews at six weeks, three, six and 12 months, then six-monthly monitoring. See the service information and cost guide and apply the same questions to every clinic.
There is no universal winner. Compare assessment, clinical responsibility, access, monitoring, continuity and the cost of your actual plan.
No. It identifies a regulated service within CQC’s scope. Your clinician still needs to assess whether the proposed treatment is appropriate.
A threshold is not a complete diagnosis. Ask how symptoms, repeat testing, the underlying cause and safety are assessed.
Ask for your diagnostic results, current prescription, treatment schedule and recent monitoring reports. Confirm acceptance and prescription responsibility with the receiving clinician.
No treatment package should be interpreted as a guarantee. Discuss your plans and any specialist assessment before starting or changing treatment.
