If you've been diagnosed with low testosterone and your GP has recommended TRT, you're likely facing the same question that almost every new patient asks us: which option should I choose?
At Lambert Medical Practice, we offer three clinically established TRT treatments — Testosterone Enanthate injections, Nebido long-acting injections, and Testogel (transdermal gel). Each has genuine advantages depending on your lifestyle, preferences, and clinical profile. This guide explains all three in plain terms so you can have an informed conversation with your doctor.
Understanding the Options
All three treatments are prescribed testosterone — the same hormone, delivered differently. The choice comes down to frequency, convenience, stability of hormone levels, and personal preference. Here's how they compare side by side:
| Factor | Enanthate | Nebido | Testogel |
|---|---|---|---|
| Delivery method | Injection (IM) | Injection (IM) | Daily gel application |
| Frequency | Every 2 weeks (clinic) | Every 10–14 weeks (4/year) | Daily (self-administered) |
| Monthly cost at Lambert | £179/month | £151/month | £132/month |
| Year 1 total (inc. assessment) | £2,357 | £2,021 | £1,793 |
| Hormone level stability | Very good | Good (may vary) | Excellent (daily dosing) |
| Needles required | Yes — clinic visits | Yes — clinic visits | No |
| Suitable for self-admin | No (clinic only) | No (clinic only) | Yes |
| Transfer risk to partner/children | None | None | Yes — must dry before contact |
Testosterone Enanthate — The Most Popular Choice
Testosterone Enanthate is a short-to-medium acting testosterone ester given as an intramuscular injection every two weeks. It's the most widely used TRT preparation in UK private clinics and accounts for the majority of new patient starts at Lambert Medical.
Why men choose Enanthate
- Predictable, stable levels: Bi-weekly injections create a consistent and well-understood hormone profile, making it easier to fine-tune your dose.
- Fast-acting: Levels peak within 24–72 hours of injection and trough just before the next dose — giving your doctor clear data points to optimise treatment.
- Most clinical data: Enanthate has been used in TRT for decades and has the most extensive long-term safety evidence of the three options.
- Clinic-administered: Your injection is given by a healthcare professional at each visit, so there's no technique to learn, no sharps disposal at home, and a built-in regular check-in with your care team.
Considerations
- Requires a clinic visit every two weeks — this suits patients who live locally to Surbiton or value regular in-person contact.
- Some men notice a slight energy dip in the days before each injection as levels trough — this is normal and usually resolves once the dose is optimised.
Nebido — Maximum Convenience
Nebido (testosterone undecanoate) is a long-acting injectable testosterone that is given just four times per year. It was designed specifically for men who want TRT with minimal disruption to their schedule.
Why men choose Nebido
- Only four clinic visits per year: An injection every 10–14 weeks means minimal time commitment — ideal for busy professionals or those who travel frequently.
- Lower overall cost: At £151/month at Lambert Medical, Nebido offers a saving of £336 in Year 1 compared to Enanthate.
- No daily routine: Unlike Testogel, there's nothing to remember each morning.
Considerations
- The loading phase: Nebido takes longer to reach stable levels. The initial two injections are given 6 weeks apart, followed by the standard 10–14 week schedule.
- Level variability: Because the interval between injections is longer, some men notice more pronounced fluctuation in energy and mood towards the end of the cycle.
- Less flexibility for dose adjustment: With injections only four times a year, it's harder to make rapid dose changes if needed.
Testogel — Needle-Free TRT
Testogel is a transdermal testosterone gel applied to the skin (typically shoulders or upper arms) every morning. It is absorbed through the skin and enters the bloodstream directly, providing a steady daily dose of testosterone without any injections.
Why men choose Testogel
- No needles, ever: Testogel is the only option that requires no injections at any point — ideal for men with needle phobia or those who strongly prefer non-injectable treatment.
- Excellent hormone stability: Daily application produces very consistent testosterone levels without the peaks and troughs seen with injectable preparations.
- Lowest monthly cost: At £132/month at Lambert Medical, Testogel offers the most affordable TRT option — a Year 1 saving of £564 versus Enanthate.
- Self-administered: Applied at home each morning — no clinic visits required beyond your monitoring appointments.
Considerations
- Transfer risk: Testosterone gel can transfer to partners or children if skin contact occurs before the gel has dried (typically 2–6 hours). This requires careful management — always cover the application area or ensure it is dry before close physical contact.
- Daily discipline required: Missing doses affects levels — Testogel works best for men who can commit to a consistent daily routine.
- Some men absorb less efficiently: Transdermal absorption varies between individuals. A small number of men do not achieve adequate levels with gel and may need to switch to injections.
Which TRT Option Is Best for You? Lambert Medical's Clinical Approach
There is no single "best" testosterone replacement therapy — the optimal choice depends on your lifestyle, clinical profile, tolerance, and long-term goals. However, at Lambert Medical we do have a clear clinical protocol that we follow for most new patients, based on years of experience managing TRT programmes.
Why We Start with Enanthate
Starting TRT is a titration process. Your body's response to testosterone supplementation is individual — some men achieve optimal levels on a standard dose; others need adjustment. During the first three to six months of treatment, we are measuring your levels at the trough (just before the next injection), adjusting your dose, monitoring haematocrit and PSA, and calibrating your protocol to your specific physiology.
Enanthate's two-week injection cycle means we have clear data points every fortnight. If your testosterone is running too high or too low, we can adjust the next injection accordingly. With Nebido's 10–14 week cycle, there are far fewer adjustment opportunities during the same period — and a dose change takes months to fully evaluate. This makes Enanthate the clinically safer and more responsive choice for new starters.
When to Transition to Nebido
Once your protocol is stable — typically after 3–6 months on Enanthate, once your dose is optimised and your monitoring bloods are consistent — patients who find the bi-weekly clinic schedule inconvenient can discuss transitioning to Nebido. At this point, we know your therapeutic range, your haematocrit tendency, and how you respond to treatment. Nebido then becomes a comfortable long-term maintenance option, requiring only four visits per year.
This approach gives you the best of both worlds: precise early titration, then long-term convenience once you're stable.
Decision Framework: Which Option Fits Your Profile?
| Your situation | Recommended option | Why |
|---|---|---|
| New to TRT — starting treatment | Enanthate | Best control during titration phase. Allows dose adjustment every 2 weeks based on blood results. |
| Stable on TRT, want fewer clinic visits | Nebido | 4 injections/year. Ideal once dose is optimised and you don't need frequent adjustment. |
| Needle aversion or strong preference for non-injectable | Testogel | No injections. Daily gel. Excellent level stability. Good for men who can commit to a daily routine. |
| Frequent travel or unpredictable schedule | Nebido (once stable) or Testogel | Nebido suits those who travel but can plan 4 annual clinic visits. Testogel allows self-admin anywhere. |
| Haematocrit tendency (high red cell count) | Testogel or lower-dose Enanthate | Daily gel avoids the high-peak injection profile. Discuss with your GP if this is a concern. |
| Living with a partner or children at home | Enanthate or Nebido | Injectable options carry zero transfer risk. Testogel requires skin-to-skin avoidance until dry. |
| Budget is a primary consideration | Testogel | Lowest monthly cost (£132/month). £564 saving vs Enanthate in Year 1. |
A Note on Switching
You are not locked in. If you start on Enanthate and decide you'd prefer the convenience of Nebido once stable, or if Testogel absorption proves suboptimal and injections are a better fit, we manage transitions routinely. What matters is that your first three to six months give us — and you — the information needed to make that long-term decision confidently.
The TRT Assessment Process
Before starting any TRT option, you'll need an initial assessment. At Lambert Medical, this involves two stages:
- Day 1 — Blood test (£149): A comprehensive 10+ marker hormone blood panel including total testosterone, free testosterone, LH, FSH, oestradiol, SHBG, and a full metabolic screen.
- Week 3 — Follow-up blood test (£60, only if Day 1 results confirm low testosterone): A second panel to confirm the result before treatment begins. This second test is only required if your first results show low levels.
- Week 4 — Free GP review: Your results are reviewed, your symptoms assessed, and your TRT plan agreed — including which of the three options is most appropriate for you.
The initial assessment pathway total is £209 (covering both blood tests and the GP review). Treatment then begins at the monthly rate of whichever option you choose.
