TRT in the UK: NHS vs Private Clinics — Costs, Wait Times, and What to Expect (2026)

The NHS Pathway

The NHS route to TRT follows NICE guidelines and involves several steps. It is free at the point of care but requires patience and persistence.

Step 1: GP appointment and initial blood tests

Your GP will order a morning blood test for total testosterone. Key details:

• Must be a fasting morning sample, taken before 10am. Testosterone peaks in the morning and can drop 20-40% by afternoon.
• The threshold is total testosterone below 8 nmol/L on two separate morning samples. One low reading is not enough — NICE guidelines require confirmation.
• Your GP will likely only test total testosterone. They will not routinely check free testosterone, SHBG, oestradiol, or prolactin unless you specifically ask.

What to push for: ask for total testosterone, free testosterone, SHBG, LH, FSH, prolactin, and thyroid function on the same blood draw. This saves months of back-and-forth if the specialist wants these later.

Step 2: Endocrinologist referral

If both blood tests confirm low testosterone, your GP refers you to an NHS endocrinologist. Typical wait time is 3-6 months for the initial appointment, depending on your NHS trust. Some areas have dedicated men's health clinics that can be faster. The endocrinologist will repeat blood work, assess symptoms, and rule out secondary causes.

Step 3: Starting treatment

If the endocrinologist confirms hypogonadism, they will initiate TRT. On NHS, your options are typically limited:

• Sustanon 250 is the most commonly prescribed injectable on NHS. A blend of four testosterone esters in a 1 mL ampoule.
• Nebido (testosterone undecanoate 1000mg/4mL) is available but less commonly prescribed on NHS due to cost. Injection every 10-14 weeks, administered by a nurse.
• Testogel (testosterone gel) is sometimes prescribed, applied daily to the upper arms or shoulders.

NHS monitoring

• Blood tests every 3-6 months initially, then annually once stable
• PSA monitoring (prostate)
• Haematocrit/FBC checks
• Limited flexibility to adjust protocol — the endocrinologist sets the dose and frequency

The Private Clinic Route

Ready to track your protocol?

• Smart reminders so you never miss a dose
• Progress tracking with photos and weight
• Medication level curves for every compound

Get Regimen Free

Private TRT clinics have grown significantly in the UK over the past few years. They offer faster access, more protocol flexibility, and more comprehensive blood work — but at a cost.

• Initial consultation: £150-300 (includes comprehensive blood panel)
• Ongoing cost: £100-250/month depending on the clinic and protocol
• Time to start: 1-4 weeks from initial blood test to first injection
• Blood work frequency: Every 6-12 weeks initially, more frequent than NHS

Popular UK private TRT clinics

• Optimale — telehealth-first, ships medication to your door. Known for supporting daily microdosing protocols.
• Leger Clinic — based in Doncaster, offers in-person and telehealth. Long-established.
• The Men's Health Clinic — multiple locations, emphasis on optimisation.
• Balance My Hormones — telehealth, works with partner pharmacies nationwide.

What private clinics offer that NHS does not

• Testosterone cypionate and enanthate — not on the standard NHS formulary but available through private clinics
• Daily or every-other-day microdosing protocols — most NHS endocrinologists prescribe fortnightly Sustanon or 10-weekly Nebido
• Comprehensive blood panels including free testosterone, sensitive oestradiol, SHBG, haematocrit, PSA, and metabolic markers
• HCG alongside TRT for fertility preservation — rarely offered on NHS
• Faster dose adjustments based on symptoms and blood work, not just lab numbers

NHS vs Private: Cost Comparison

Sustanon 250 vs Nebido: The UK Reality

Sustanon 250

• Blend of 4 testosterone esters in 1 mL (30mg propionate, 60mg phenylpropionate, 60mg isocaproate, 100mg decanoate)
• Standard protocol: 1 mL every 2-3 weeks (NHS) or split into smaller, more frequent doses (private)
• The multi-ester blend creates a unique PK profile — levels spike quickly then have a stepped decline
• Microdosing Sustanon: A growing number of UK men split their Sustanon into daily subQ injections using insulin syringes. At 250 mg/mL, a typical daily dose of 17-25 mg requires only 7-10 units (0.07-0.10 mL).

Nebido (Testosterone Undecanoate 1000mg/4mL)

• Long-acting testosterone undecanoate. Single 4 mL injection every 10-14 weeks.
• Administered by a healthcare professional (the 4 mL volume makes self-injection impractical for most).
• Least frequent injection schedule. Relatively stable levels once at steady state.
• Less dose flexibility. If you have side effects, you are waiting weeks for the dose to clear.

Blood Work: What to Actually Test

NHS GPs will typically only check total testosterone, which misses the full picture. Whether you are on NHS or private, here is what you should be monitoring:

Where to Get Private Blood Tests

• Medichecks — finger-prick or venous draw. Male Hormone Check from £39. TRT Monitoring panel from £89.
• Thriva — home finger-prick kits with app-based results.
• Forth — similar to Thriva, with optional GP consultations.
• NHS GP — free but limited panel. Worth asking for everything in a single request.

When to test: Fasting morning sample before 10am, at trough (the morning of your injection day, before pinning). This shows your lowest level and is the most clinically useful measurement.

Tracking Your TRT Protocol

Whether you are on fortnightly Sustanon, 10-weekly Nebido, or daily microdosing, keeping track of injections, doses, and blood work matters. Regimen works with any ester, any frequency, and any injection schedule — including the unique multi-ester pharmacokinetics of Sustanon 250. It also reports in nmol/L for UK users.
