How to get TRT in the UK: NHS and private routes

Getting testosterone replacement therapy in the UK runs through one of two doors: the NHS or a private clinic. Both start the same way — symptoms plus two morning blood tests showing low total testosterone.

The NHS route

GP appointment. Describe symptoms (fatigue, low libido, brain fog, low mood). The GP orders morning blood tests — total testosterone plus SHBG, LH and often prolactin.
Threshold. The BSSM-aligned pathway assesses men at total T below 12 nmol/L; many local NHS labs use lower cut-offs (commonly 8–12 nmol/L) before offering treatment (BSSM position statement). Above the threshold, treatment is usually declined even with symptoms.
Endocrinology referral. Most GPs defer to an endocrinologist; waits of months are widely reported by clinics and patient groups.
Treatment and monitoring. If started, the NHS prescribes and monitors — you pay prescription charges (or nothing, depending on age/exemptions).

The private route

Private clinics run the same blood-first logic but set their own (usually higher) thresholds and skip the referral queue. Based on the pages we checked, the process is: online hormoneQuiz or consult booking → blood draw (at a clinic site, or a kit) → doctor review → prescription and ongoing monitoring. Costs run from £59.99/month (Optimale, Manual) to £189+/month all-in — verified prices in our price registry.

What to check whichever door you pick

A GMC-registered doctor must prescribe. Testosterone is a prescription-only medicine (POM) in the UK.
Two morning total-T tests before diagnosis is standard good practice (testosterone varies day to day).
Monitoring cadence: PSA and haematocrit checks are part of safe TRT — see risks and monitoring.

The grey market warning

Testosterone bought without prescription — from online sellers, gyms or "mates rates" suppliers — is illegal in the UK without a prescription, counterfeit-prone, and unmonitored. The Pharmaceutical Journal and BBC coverage of the UK TRT boom both flag the risks of buying outside regulated care.
