Epi-Testosterone (Epi-T)


What is epi-testosterone?

Epi-testosterone, also known as 3-epitestosterone, is a naturally occurring isomer of testosterone, a hormone produced by the testicles. It is present in small amounts in the human body, and its levels are usually much lower than those of testosterone.

How is epi-testosterone related to testosterone?

Epi-testosterone is a testosterone isomer, meaning it has a similar chemical structure to testosterone but with a different arrangement of atoms. While testosterone is an androgen, a hormone that promotes the development of male characteristics, epi-testosterone has weaker androgenic activity.

How is epi-testosterone measured in a laboratory setting?

Epi-testosterone can be measured through a blood or urine test. In a blood test, a healthcare provider will take a sample of the patient's blood and send it to a laboratory for analysis. In a urine test, the patient will collect a sample of their urine and bring it to a laboratory for analysis.

What is the normal range for epi-testosterone levels in the body?

The normal range for epi-testosterone levels in the body is not well established, as levels can vary widely depending on the individual and the specific circumstances. However, the ratio of testosterone to epi-testosterone (T/E ratio) is often used as an indicator of testosterone abuse in sports doping tests. In these cases, a T/E ratio greater than 4:1 is generally considered suspicious.

What can cause abnormal epi-testosterone levels in the body?

Abnormal epi-testosterone levels can be caused by a variety of factors, including:

  • Testosterone abuse or doping in sports.
  • Certain medical conditions such as adrenal gland disorders or pituitary gland disorders.
  • The use of certain medications or supplements.

How is an abnormal epi-testosterone level treated?

Treatment for an abnormal epi-testosterone level will depend on the underlying cause. If the abnormal level is caused by testosterone abuse or doping, treatment may involve the use of medications or supplements to help the body return to normal hormone levels. If the cause is a medical condition, treatment may involve medications or surgery to correct the condition.

What other hormones or substances are commonly tested alongside epi-testosterone?

Other hormones or substances that may be tested alongside epi-testosterone include:

  • Testosterone, the primary male sex hormone.
  • Estradiol, a form of estrogen, the primary female sex hormone.
  • Nandrolone, a synthetic anabolic steroid.
