Trenbolone Enanthate (Trenabol)

Trenbolone enanthate, known by the nickname Trenabol, is a synthetic and injected anabolic–androgenic steroid (AAS) and a derivative of nandrolone which was never marketed. It is the C17β enanthate ester and a long-acting prodrug of trenbolone.

Trenbolone enanthate was never approved for medical or veterinary use but is used in scientific research and has been sold on the internet black market as a designer steroid for bodybuilders.

Side Effects

Trenbolone enanthate, being a potent anabolic steroid, has several potential side effects stemming from its particularly strong androgenic properties and its regulation on human hormones.

Psychological

Anabolic-androgenic steroid (AAS) users report significant psychological changes. Fluctuation in testosterone, a key AAS, affects the brain’s structure and function, potentially leading to mood disorders and aggressive behavior.

Trenbolone enanthate users have reported:

• Increased aggression

• Mood instability

• Impaired social interactions

Prolonged use of AAS may also lead to psychological dependence, with approximately 1/3 of users experiencing withdrawal symptoms upon cessation.

Reproductive Health

Anabolic-androgenic steroids impact male reproductive health. Their misuse can lead to a condition known as anabolic steroid-induced hypogonadism (ASIH), where natural testosterone production is suppressed.

The decreased testosterone production leads to:

• Decreased sperm production

• Prolonged infertility even after stopping use

Chronic AAS use increases the risk of infertility due to its impact on hormonal balance, and some effects such as gynecomastia may not be reversible.

Androgenic

Trenbolone enanthate can include several androgenic side effects such as:

• Increased body hair growth

• Acne

• Potential baldness in predisposed individuals
