How to Get TRT on the NHS: Step-by-Step

The NHS Route to Testosterone Replacement Therapy

Private TRT clinics advertise heavily, but you can get testosterone replacement therapy through the NHS. The process is slower and more restrictive, but it's free at the point of use.

This guide walks you through exactly what to expect - from GP appointment to ongoing treatment. The NHS pathway for prescribed cannabis is even narrower — my piece on medical cannabis access on the NHS covers that separately.

NHS vs Private: Key Differences

| Factor | NHS | Private | |--------|-----|---------| | Cost | Free | £60-120/month | | Wait time | 3-6 months typically | 1-2 weeks | | Blood tests | Basic only | Comprehensive | | Protocol flexibility | Limited | Personalised | | Injection frequency | Every 3-4 weeks | 2-3x per week | | HCG | Rarely prescribed | Usually available |

Bottom line: NHS TRT exists but is basic. Many men who start on NHS eventually switch to private for better protocols — my deep dive on NHS TRT vs private TRT in the UK covers the trade-offs in detail.

Step 1: GP Appointment

Book a routine appointment (not emergency). You need time to discuss symptoms properly.

What to say: Be direct but specific. Don't just say "I think I have low testosterone."

Better approach:

"I've been experiencing persistent fatigue, low libido, and reduced muscle mass for several months. I understand these can be symptoms of low testosterone. Could I get my levels checked?"

Symptoms to mention:

• Low energy despite adequate sleep
• Reduced sex drive
• Loss of muscle mass/strength
• Brain fog or difficulty concentrating
• Low mood or irritability

Don't mention:

• Steroids or bodybuilding
• Wanting "optimal" levels
• Reading about TRT online (triggers dismissive responses)

---

Step 2: Blood Test

If your GP agrees, you'll get a blood test form.

Critical: Request a morning appointment (8-11am). Testosterone peaks in the morning.

What the NHS tests:

• Total testosterone only (usually)
• Sometimes SHBG (if you're lucky)
• Rarely free testosterone

What they DON'T test:

• Free testosterone
• Estradiol
• LH and FSH
• Prolactin
• DHEA-S

This is a major limitation. NHS relies on total testosterone alone.

Pre-test preparation:

• Fast 8-12 hours (water OK)
• No alcohol 48 hours before
• Normal sleep schedule
• Morning appointment essential

---

Step 3: Results Appointment

NHS reference ranges vary by lab, but typically:

• 8-29 nmol/L for total testosterone

The problem:

• 8 nmol/L is technically "normal"
• Most men feel terrible below 12 nmol/L
• NHS often won't treat unless below 10 nmol/L

Possible outcomes:

Result A: Below 8 nmol/L

• Likely referred to endocrinologist
• NHS will probably treat
• Waiting list: 3-6 months

Result B: 8-12 nmol/L

• "Borderline" - may refuse treatment
• GP might retest in 3 months
• You may need to push harder

Result C: Above 12 nmol/L

• Likely dismissed as "normal"
• Even if you have symptoms
• Consider private testing

---

Step 4: Endocrinologist Referral (If Approved)

If your testosterone is low enough, you'll get a referral.

Waiting times:

• Routine: 18 weeks (NHS target)
• Reality: Often 3-6 months

What the endocrinologist does:

• Confirms low testosterone
• Rules out other causes (pituitary issues, etc.)
• Discusses treatment options
• Prescribes if appropriate

They'll test:

• Full hormone panel
• LH and FSH (pituitary function)
• Prolactin
• Thyroid
• Possibly MRI (if concerned about pituitary)

---

Step 5: Starting Treatment

If approved, typical NHS protocol:

Sustanon injections:

• 250mg every 3-4 weeks
• Given at GP surgery or self-inject

Problems with this protocol:

• Levels peak then crash
• Many men feel worse by week 3
• Rollercoaster of symptoms
• Not physiological dosing

Alternative: Testosterone gel

• Daily application
• Steadier levels
• Less effective for many men

What's rarely offered:

• HCG (preserves fertility)
• Anastrozole (manages oestradiol)
• Twice-weekly injections (modern protocol)

---

Step 6: Ongoing Monitoring

NHS monitoring is minimal:

• Blood tests every 6-12 months
• Usually just total testosterone
• PSA check (if over 40)
• Haematocrit (blood thickness)

What's often missed:

• Oestradiol levels
• Free testosterone
• SHBG changes
• Symptom review

Common NHS Problems

Problem 1: "You're Normal"

GP says: "Your testosterone is 10 nmol/L - that's normal."

Reality:

• 10 nmol/L is low-normal
• Reference ranges include sick, elderly men
• Many men feel rubbish at this level

Response:

• Ask for referral anyway
• Get private testing (£79)
• See different GP

Problem 2: Outdated Protocols

NHS gives: Sustanon every 3 weeks

Better protocol: Enanthate/Cypionate twice weekly

Why outdated:

• NHS slow to update
• Cheaper to prescribe Sustanon
• Less monitoring needed

Problem 3: No HCG

NHS rarely prescribes HCG because:

• Seen as fertility treatment only
• More expensive
• Requires more monitoring

Problem:

• Testosterone shuts down natural production
• Without HCG, testicular atrophy likely
• Fertility concerns if you want children

---

When to Consider Private Instead

Go private if:

• ✅ NHS refuses treatment despite symptoms
• ✅ You want modern protocols (twice-weekly)
• ✅ You need HCG for fertility preservation
• ✅ You want comprehensive monitoring
• ✅ You can't wait 3-6 months
• ✅ You want personalised dosing

Cost consideration:

• NHS: Free
• Private: £60-120/month

Many men start NHS, then switch to private once they realise the limitations.

Tips for Success on NHS

1. Document symptoms Keep a symptom diary for 2-4 weeks before appointment. Specific examples beat vague complaints.

2. Mention quality of life "My low energy is affecting my work performance and relationship" carries more weight than "I feel tired."

3. Ask for referral If GP is dismissive, ask directly: "Given my symptoms and borderline results, could I see an endocrinologist?"

4. Get second opinion Different GPs have different approaches. If one refuses, try another.

5. Consider bridging Start private while waiting for NHS. Many clinics offer short-term bridging.

---

Alternative: NHS Shared Care

Some private clinics offer shared care agreements:

• Private consultation and diagnosis
• NHS GP prescribes (saving you money)
• Private monitoring

Requirements:

• GP must agree (not all do)
• Clinic must provide clear protocol
• Regular communication between private and NHS

Not guaranteed - depends on your GP.

---

The Reality

NHS TRT exists but is frustrating:

• Long waits
• Basic protocols
• Limited monitoring
• One-size-fits-all approach

However:

• It's free
• It's legitimate
• It helps many men
• It's a starting point

Our view: Try NHS first if budget is tight. If the protocol doesn't work or you're refused, go private. The diagnosis and initial bloodwork are valuable either way.

FAQ

How long does NHS TRT take from first appointment? 3-6 months typically. GP appointment → blood test → results → referral → endocrinologist → treatment.

Will NHS prescribe HCG? Rarely. Usually only if you're trying to conceive. Most men buy privately or go without.

Can I self-inject on NHS? Sometimes. Depends on your GP surgery. Some insist on nurse administration (inconvenient).

What if my GP refuses testing?

• See different GP
• Get private blood test (£79)
• Present results to GP
• Or go straight to private clinic

Is NHS testosterone the same quality? Yes. The medication is identical. The protocol (dosing, frequency) is what's different.

Can I switch from NHS to private? Yes, easily. Private clinics accept NHS diagnoses. You may need new blood work.

Summary

NHS route:

1. GP appointment
2. Blood test (morning!)
3. Wait for results
4. Referral if low
5. Endocrinologist (3-6 month wait)
6. Basic TRT protocol
7. Minimal monitoring

When it works: Low testosterone, patient GP, not in a hurry

When to go private: Borderline results, want modern protocol, need HCG, can't wait
