Men researching testosterone treatment want to know which tests they need, who decides, what it costs and how they will be monitored. We reviewed the home page, the main TRT page and, where linked, the price page of eight UK providers that offer it.
Key findings
On the clinical pathway, these pages were detailed. The area to check is claims.
The providers we reviewed
We do not name the providers: some observations relate to advertising rules, and a page review is not a fair basis for public judgements about individual businesses. Page addresses, capture times and SHA-256 hashes are held on file; a provider in the sample can ask for its own coding.
“Not found” means not found in reviewed pages: we did not find that information on the two or three pages reviewed for that provider; it may appear elsewhere on its website.

What else we recorded on these eight providers’ pages
All eight described blood tests before treatment and named a clinician; seven set out prices for more than one stage and seven described ongoing monitoring. Five gave a figure for how many men have low testosterone, four of them with a linked or cited source for at least one figure, and five compared their approach with GP or NHS care. Seven said treatment is prescribed only if clinically appropriate. Six stated registration with a UK health-care regulator, and four showed a treating clinician’s register number or a link to a register entry. Five mentioned a repeat or morning test before diagnosis. Three home pages named a testosterone product or form, one only in its menu, and one home page showed a monthly treatment price. Four had purchase buttons; all were for blood test kits or test-and-consultation bundles, not medicine.
The comparisons with GP or NHS care mostly concerned waiting times and the testosterone level at which treatment is considered. Some also covered the range of medicines, cost, access to a specialist or the breadth of testing and monitoring. On 26 August 2026 the ASA ruled against Facebook ads from two other providers: one for prevalence statistics that went beyond its evidence, the other for unsupported claims to test more thoroughly than GPs. Neither provider is in this sample. We did not assess whether any figure or comparison in our sample is accurate; we recorded that it is there, and whether a source sits next to it.

A practical review of your own pages
Six questions, several with what we saw on the eight providers’ pages. Open your home page, your main treatment page and your price page and record the evidence, the person responsible and the next change in the 10-question worksheet that accompanies this review.
- Explain the blood tests, their timing and the rule for confirming a result. One provider’s treatment page explains which blood markers it tests and why, the morning timing of samples, the two-test rule before diagnosis and what happens if results are not low; another explains in plain terms why a second test confirms a low first result before treatment is considered.
- Name the clinician, link their register entry and say treatment may not be offered.
- Price tests, consultations, treatment and monitoring separately, and say what is excluded. The clearest price pages did this: one lists a fee for each stage and the monitoring tests for the first year, and another says plainly that medication is not included in the listed consultation and test fees.
- Link it, and check the wording claims no more than the source found. One provider footnoted a prevalence figure to a published diabetes study; three others linked figures to a PubMed record, a news report and a professional society guidance document. The ASA also looks at whether a claim matches what the source actually found, so a link is where checking starts, not where it ends.
- Avoid them unless you hold robust evidence.
- Keep product names and medicine prices to factual inner pages.
Observed page structure, not an endorsement of any provider or a judgement of clinical quality. A content-review aid, not a regulatory checklist or legal advice. Your clinic’s responsible clinician and compliance adviser should approve clinical information and claims before publication.
How this relates to AI visibility: an AI assistant may repeat what it finds on a provider’s website, including a figure or a comparison. These checks identify information a reader can verify; they do not show whether a page is cited in AI answers. Our page on AI visibility for TRT clinics explains how we test the answers and work within the advertising rules. Download all fourteen recorded features for each provider (CSV).
Method, boundaries and corrections
Read the full method, boundaries and corrections
On 23 September 2026 we ran two public web searches for private testosterone treatment in the UK. In result order, we took the first eight distinct providers offering testosterone treatment to UK patients, excluding comparison sites. One candidate returned HTTP 429 to our capture tool and was replaced by the next. One provider has no separate TRT page, so its home page served as both. Provider letters were assigned at random and do not follow search order. The sample is not random, and the search order favours providers that are already easy to find.
We captured the returned HTML with UTC timestamps and SHA-256 hashes and extracted the text and link list. We did not run JavaScript, so content that loads only in the browser, and anything shown only in images, was not reviewed. We did not contact providers, buy tests, check professional registers or visit other pages.
Each provider was coded on fourteen features using a written codebook. The counts and examples were checked against the retained captures, and the sources were re-read before publication. Four codes were corrected before publication: three figures first coded as unsourced were found to be hyperlinked to sources, and the register-number feature was limited to treating clinicians, so a pharmacist’s number alone does not count. Presence of a feature does not establish its accuracy or completeness.
The review questions draw on MHRA guidance for providers of medicinal treatment services, the CAP Code and the ASA rulings above. This narrow page review does not determine whether any provider complies with them.
