ROHM Testosterone Undecanoate / Nebido / TRT 250mg x 10ml – Classification
ROHM Testosterone Undecanoate, commonly known by the brand name Nebido, is a long-acting injectable testosterone preparation used as part of Testosterone Replacement Therapy (TRT). It is clinically prescribed to adult men diagnosed with testosterone deficiency (hypogonadism), where the body does not produce adequate levels of natural testosterone.
In the United Kingdom, Testosterone Undecanoate is classified as:
- Prescription-Only Medicine (POM)
- Anabolic Androgenic Steroid (AAS)
- Controlled medicinal hormone
Due to its potency and long-acting nature, this medication must be used under the guidance of a qualified healthcare professional. ROHM Testosterone Undecanoate 250mg x 10ml is manufactured to pharmaceutical standards, ensuring high purity, consistency, and therapeutic reliability.
What is ROHM Testosterone Undecanoate / Nebido / TRT 250mg x 10ml?
ROHM Testosterone Undecanoate 250mg x 10ml is a slow-release injectable testosterone ester designed to restore and maintain optimal testosterone levels in men requiring long-term hormone replacement therapy.
Unlike short-acting testosterone injections, this formulation is suspended in an oil base that allows testosterone to be released gradually into the bloodstream over several weeks. This results in:
- Stable hormone levels
- Reduced injection frequency
- Improved patient compliance
This product is widely prescribed across the UK and Europe for men suffering from symptoms such as fatigue, reduced libido, muscle loss, mood changes, and decreased bone density associated with low testosterone levels.

How Does ROHM Testosterone Undecanoate / Nebido / TRT 250mg x 10ml Work?
ROHM Testosterone Undecanoate works by supplementing the body’s natural testosterone supply when endogenous production is insufficient.

This long-acting mechanism minimises hormonal fluctuations, which are often responsible for side effects seen with short-acting testosterone injections.
