Testosterone undecanoate is a long-acting ester of testosterone, available in both injectable and oral formulations. It is primarily used for testosterone replacement therapy (TRT) in men with confirmed testosterone deficiency (hypogonadism), restoring physiological testosterone levels to alleviate symptoms like fatigue, low libido, and muscle loss.

Once administered, testosterone undecanoate is slowly released into the bloodstream, where the ester is removed, leaving free testosterone. This increases serum testosterone levels, restoring them to a healthy range, which in turn supports muscle growth, sexual function, red blood cell production, and overall well-being.
Injectable TU: Minimal fluctuations in testosterone levels, excellent safety profile (no polycythemia or lipid disturbances reported).
Effective & Long-Lasting TRT
Sustained testosterone levels: Injectable TU (Aveed, Nebido) maintains stable testosterone for up to 12 weeks, reducing the “roller-coaster” effect of shorter esters.
Convenient dosing: After 2 loading shots, only 3–4 injections per year are needed.
Improves Sexual Health
Erectile dysfunction (ED): Long-term TU therapy (12 years) significantly reduces ED severity, especially in men with moderate/severe ED.
Libido: Restores sexual desire in hypogonadal men and postmenopausal women when combined with estrogen.
Cardiometabolic Benefits
Reduced cardiovascular risk: Long-term use lowers major adverse cardiovascular events (MACE) and mortality.
Improved insulin sensitivity: Studies show reduced HOMA-IR, fasting glucose, and HbA1c in men with type 2 diabetes.
Body composition: Decreases fat mass while increasing lean muscle mass.
Prostate & Longevity Benefits
Lower prostate cancer risk: Observational data suggest reduced incidence compared to untreated hypogonadal men.
Improved quality of life: Enhances mood, energy, and muscle strength.
Testosterone undecanoate is a preferred long-acting TRT due to its stable pharmacokinetics and reduced dosing frequency. The injectable form (Aveed/Nebido) is ideal for sustained therapy.
Like all anabolic-androgenic steroids, testosterone undecanoate can cause side effects, especially if misused or taken without medical supervision. These may include:
