Trenbolone undecanoate

Trenbolone Undecanoate

Trenbolone undecanoate is a synthetic anabolic-androgenic steroid (AAS) and a derivative of nandrolone. It is an ester of trenbolone, which is used in veterinary medicine to promote muscle growth in livestock. Trenbolone undecanoate is not approved for use in humans and is classified as a controlled substance in many countries.

Chemical Structure and Properties

Trenbolone undecanoate is the undecanoate ester of trenbolone. The chemical structure of trenbolone includes three conjugated double bonds, which contribute to its high affinity for the androgen receptor. The undecanoate ester increases the lipophilicity of the molecule, allowing for a prolonged release and action when administered intramuscularly.

Chemical structure of Trenbolone undecanoate

Mechanism of Action

Trenbolone undecanoate binds to the androgen receptor with high affinity, leading to increased protein synthesis and nitrogen retention in muscle tissues. This results in enhanced muscle growth and strength. It also has anti-catabolic effects, reducing the breakdown of muscle proteins.

Veterinary Use

In veterinary medicine, trenbolone undecanoate is used to increase the feed efficiency and muscle mass of cattle. It is often administered as an implant under the skin of the ear. The use of trenbolone in livestock is regulated to ensure that residues do not remain in meat products intended for human consumption.

Side Effects

The use of trenbolone undecanoate can lead to several side effects, including:

• Androgenic effects such as acne, increased body hair, and voice deepening.
• Cardiovascular issues, including increased blood pressure and changes in cholesterol levels.
• Potential liver toxicity with prolonged use.

Legal Status

Trenbolone undecanoate is classified as a Schedule III controlled substance in the United States under the Anabolic Steroid Control Act. It is illegal to use or possess without a prescription, and it is not approved for human use.
