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.

Quick summary: Testosterone Enanthate is our most popular option for men who want stable, monitored care. Nebido suits men who want maximum convenience with just four injections per year. Testogel is ideal for those who prefer to avoid needles entirely. All three include identical monitoring at Lambert Medical — the difference is only in how the testosterone is delivered.

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:

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 Option Does Lambert Medical Recommend?

We don't make a blanket recommendation — the right choice depends on your individual circumstances. However, as a general guide:

  • If you want close GP monitoring and proven stability, Enanthate is the right starting point for most men.
  • If you travel frequently or have a demanding schedule that makes regular clinic visits difficult, Nebido is the logical choice.
  • If you strongly dislike needles or want to avoid clinic visits, Testogel provides excellent results for most patients.
All three options at Lambert Medical include: Full monitoring bloods (testosterone, haematocrit, PSA, liver function), GP review appointments, and no hidden extras. The prices above are all-inclusive — there are no additional consultation fees on top.

The TRT Assessment Process

Before starting any TRT option, you'll need an initial assessment. At Lambert Medical, this involves two stages:

  1. 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.
  2. 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.
  3. 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.

Frequently Asked Questions

Can I switch between TRT options if I change my mind?
Yes. If you start on one option and find it doesn't suit your lifestyle or you're not achieving optimal levels, we can discuss switching. There is a clinical transition period, and your GP will advise on the best approach.
Is TRT available on the NHS?
TRT is available on the NHS for men with clinically confirmed hypogonadism, but waiting times for endocrinology referral can be 6–18 months. Private TRT at Lambert Medical offers the same clinical standard with same-week assessment availability.
How long before I feel the benefits of TRT?
Most men notice improved energy and mood within 3–6 weeks. Libido improvement is typically seen within 4–8 weeks. Full benefits — including muscle tone, body composition changes, and cognitive clarity — develop over 3–6 months.
Do I need TRT for life?
TRT is a long-term treatment for most men with primary hypogonadism. However, if your low testosterone has a reversible cause (obesity, sleep apnoea, medication side effects), treating the underlying cause may allow you to discontinue TRT. Your GP will review this regularly.
Does TRT affect fertility?
Yes — exogenous testosterone suppresses the pituitary's signal to the testes, which reduces sperm production. If you are planning to father children, discuss this with your GP before starting TRT. Alternative approaches exist for men who want to preserve fertility.
