Nebido (Testosterone Undecanoate) in Bangkok

Long-acting testosterone replacement for patients who value fewer injections and a clear, physician-guided follow-up plan.

The short answer

What is Nebido?

Nebido is a long-acting testosterone undecanoate injection used for TRT in men with testosterone deficiency. Kauri offers Nebido in Bangkok. It releases testosterone gradually, allowing longer intervals between injections than testosterone enanthate, with a schedule guided by symptoms and blood results.

Treatment goals

What benefits can testosterone replacement offer?

The goal is to treat testosterone deficiency and improve the symptoms it is causing. Benefits develop at different speeds and vary between patients.

Sexual wellbeing

For men with testosterone deficiency, TRT can improve libido and related sexual symptoms. We also assess other contributors when erections remain a concern.

Muscle and bone health

Restoring testosterone can support lean body mass and bone density over time. Exercise, nutrition and everyday health habits complement treatment.

Progress that matters to you

We review the symptoms that led you to treatment, including energy and wellbeing where relevant. Your response and blood results guide the next step.

What is in Nebido, and how does it work?

Nebido contains testosterone undecanoate in an oil-based injection. The standard presentation contains 1000 mg of testosterone undecanoate in 4 mL; that figure describes the ester, rather than 1000 mg of free testosterone. A healthcare professional administers it into a muscle, where it forms a depot that releases testosterone over an extended period.

Why choose a long-acting testosterone injection?

Nebido can be a convenient option for patients who prefer fewer injection appointments and a longer treatment interval. At Kauri, we coordinate injections with your follow-up plan so your treatment remains organized around your routine. Its long duration also means changes to treatment develop more gradually, which is part of the discussion when choosing between Nebido and enanthate.

How often are Nebido injections given?

Published Nebido product information describes maintenance injections every 10–14 weeks. During the starting phase, the first interval may be shortened to as little as 6 weeks according to symptoms and testosterone results. Your physician chooses your dates. The starting phase and maintenance phase serve different purposes, so the first follow-up date may differ from your later schedule.

What happens at a Nebido appointment?

We review your progress and planned injection date, then administer the medicine slowly into the gluteal muscle. The clinical team observes you during and immediately after the injection. This allows us to check that you feel well before you leave. We also explain your next appointment and how it fits with Kauri's monthly monitoring.

How do we monitor Nebido between injections?

A longer injection interval still includes active follow-up. At Kauri, we review symptoms, testosterone and relevant laboratory markers monthly. A testosterone sample taken toward the end of the interval can help the physician assess whether the next injection date needs adjusting. Blood counts, blood pressure and prostate-related assessment where relevant remain part of the overall plan.

Why is Nebido given slowly in the clinic?

Nebido is an oil-based medicine designed for slow, deep intramuscular administration by a healthcare professional. Observation during and just after the injection is part of routine care. Rarely, an immediate reaction can cause coughing, breathing difficulty or dizziness; tell the team straight away if you feel unwell. This is why careful administration and an attended appointment are built into the treatment.

Both aim to restore an appropriate testosterone level and improve symptoms associated with deficiency. The best choice is the one that fits your clinical response and routine.

How do I start TRT at Kauri?

Start with a private consultation about your symptoms, medical history, current medicines and treatment goals. For blood testing, you can choose Kauri's comprehensive Hormone Optimization Panel, a more focused hormone panel, or provide recent results from another laboratory. We review the results in context, explain whether any additional tests are needed and give you a clear treatment and monthly follow-up plan.

Confident treatment, with attentive follow-up

Testosterone therapy is an established treatment for testosterone deficiency. At Kauri, we prescribe pharmaceutical-grade testosterone and use ongoing review to keep care aligned with your response. Acne, injection-site discomfort, fluid retention or a rise in red blood cells can occur; monitoring helps us identify and manage changes. Tell us about fertility plans, sleep apnoea, heart conditions, prostate or breast cancer concerns and your medicines before treatment, so the plan addresses what matters for your health.

What if having children is part of my plan?

Tell Kauri before starting or changing TRT. External testosterone can reduce sperm production, including with either injection option. We can discuss fertility-focused evaluation and alternatives where appropriate, so your hormone treatment and reproductive goals are considered together.

Patient questions

Nebido (Testosterone Undecanoate): frequently asked questions

Does Kauri offer Nebido in Bangkok?

Yes. Kauri offers Nebido testosterone undecanoate treatment at BTS Punnawithi, with physician assessment, appropriate blood work and monthly follow-up. Testing can be arranged at Kauri, or you can provide recent results from another laboratory for review.

Is Nebido the same as testosterone enanthate?

Both deliver testosterone, but use different esters and release patterns. Nebido contains testosterone undecanoate and has a longer injection interval. Enanthate is given more frequently and allows adjustments over shorter treatment cycles.

Does Nebido mean I only need follow-up every 3 months?

No. Injection appointments and monitoring are different parts of care. Nebido maintenance intervals are commonly 10–14 weeks in product guidance, while Kauri reviews symptoms and relevant blood markers monthly.

When can Nebido start helping symptoms?

Some testosterone-related sexual symptoms can improve over the first weeks of effective treatment, while other changes take longer. We review your response over time. The long injection interval does not mean you must wait until the next injection before discussing progress.

Can I switch from Nebido to testosterone enanthate?

A physician can arrange a change when appropriate. Because Nebido continues releasing testosterone for an extended period, the transition is planned using your last injection date, blood results and symptoms.

What if I travel or miss my planned Nebido date?

Contact Kauri before the appointment if possible. We can review the schedule and explain the appropriate next step. Keep your prescription and a record of the medicine, dose and last injection date so care can be coordinated.
