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.
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.
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:
- GP appointment
- Blood test (morning!)
- Wait for results
- Referral if low
- Endocrinologist (3-6 month wait)
- Basic TRT protocol
- 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
