Testosterone undecanoate is a steroid form of testosterone that contains a larger ester (undecanoate) than many other types. It is available in oral and injectable form, and there are different brand names for each. For example, among the Testosterone Undecanoate for injection brands, the drug Nebido is very popular.
Testosterone Undecanoate was developed for medical use in the treatment of low testosterone levels. But it quickly caught the attention of anabolic steroid users because it offers all the benefits you would expect from synthetic testosterone.

What is Testosterone Undecanoate?
It is a long-acting, slow-release steroid that when used in an injectable form can stay in the body for several months. Due to this slow activity, its positive effects may be significantly delayed and may not even begin to provide benefits until after a normal length steroid cycle has ended. This makes Testosterone Undecanoate less convenient for many performance enhancing steroid users compared to other testosterone esters.
To improve performance, users must include Testosterone Undecanoate in a cycle of at least 16 weeks. Otherwise, this slow-acting form of testosterone won’t have enough time to do any good.

Benefits of Testosterone Undecanoate
This steroid can be used in two main ways:
- As a low dose testosterone substitute during a steroid cycle when you need an external source of testosterone to maintain levels and function due to hormonal suppression caused by other compounds.
- Testosterone undecanoate alone can be used as a performance enhancing compound at higher doses.
The performance enhancing effect of testosterone on the male body in high doses includes:
- Greater nitrogen retention: this avoids the loss of muscle mass.
- Improves protein synthesis and forms the basis for muscle growth.
- Increases the production of the growth hormone IGF-1: stimulates the growth of skeletal muscles and the production of more proteins.
- Increases the number of red blood cells, which improves oxygenation of the body.
- Reduces the level of glucocorticoids.
Testosterone Undecanoate Dosage and Cycle Length
The cycle length should be at least 16 weeks. The dose depends on the purpose for which you use it:
- For testosterone support when using other compounds, 1000mg for 12 weeks is sufficient.
- When the drug is used as the primary anabolic compound or in conjunction with other steroids, the 1000mg dose may be more common. At least once a month or, in some cases, twice a month.
- When used medically to treat low testosterone, the drug is usually given every 3 months at a dose of 1000mg.

Post cycle therapy
The post cycle treatment schedule while using testosterone undecanoate will depend on any other compounds used. The effect of the drug can last for two or even three months after the end of the course, so the treatment can be postponed for this period.
