What Is Delatestryl?

A hormone class known as an androgen produces Delatestryl, sometimes referred to as testosterone enanthate. It is typically utilized in males who have lower testosterone levels than normal. Delatestryl is administered intramuscularly with a needle and is offered in generic form.

The molecular structure of Delatestryl when it is active in the body has a 17-beta-hydroxy group. It can remain effective for a longer time thanks to this structure. The 17-beta-hydroxy group disintegrates once within the body, producing free testosterone.

Delatestryl is a member of the androgens family of drugs, which mimic the effects of male hormones. In order to make up for the missing hormone, it is administered to men who suffer from illnesses brought on by low levels of testosterone. It's crucial to establish the deficiency through symptoms and blood testing before utilizing testosterone enanthate.

This drug's main goal is to make up for the body's deficiency in testosterone. It should only be used in cases when a testosterone deficit has been identified through blood tests and symptoms.

The chemical name for testosterone enanthate is androst-4-en-3-one, 17-[(1-oxoheptyl)-oxy]-, (17)-. 

Structural formula


Usage in men and women

Delatestryl is a prescription medication used to treat low levels of testosterone, a natural hormone found in men. It is intended for males who do not make enough testosterone naturally. It can also be used to aid adolescent males who are experiencing delayed puberty in some situations. In addition, testosterone may be given to women to treat some types of cancer.

Testosterone is required for a variety of normal male processes, including the development of genitals, muscles, and bones. It also aids in the initiation of normal sexual development during puberty. Delatestryl belongs to the class of medicines known as androgens. It works by influencing several body systems to support appropriate development and functioning. In some situations, testosterone can be used to induce puberty in boys who have delayed puberty, as well as to treat some types of breast cancer in women.

Delatestryl is used to treat diseases caused by low testosterone levels in men and boys, such as delayed puberty, impotence, and other hormonal abnormalities. It is crucial to highlight, however, that testosterone injections should not be used only to address low testosterone due to ageing in the absence of certain medical issues. Delatestryl is used in women to treat metastatic breast cancer that has spread to other regions of the body and cannot be treated surgically.

In summary, Delatestryl is used for the following purposes:

  • Treatment of breast cancer in women.
  • Management of low testosterone levels.
  • Assistance in inducing puberty in certain children with delayed puberty. 

How to take Delatestryl (Intramuscular)?

Testosterone is usually given through injections, either beneath the skin or into a muscle. These injections are typically given every 2 to 4 weeks and must be delivered by a healthcare expert.
The duration of testosterone injection treatment will vary based on the problem being treated. It is critical to understand that testosterone injections may raise blood pressure, increasing the risk of a heart attack, stroke, or even death. As a result, regular blood pressure monitoring is required. In rare circumstances, it may be necessary to stop using testosterone or begin taking blood pressure medicine.
