boldenone undecylenate

Boldenone undecylenate is a synthetic androgen and anabolic steroid (AAS) medication primarily used in veterinary medicine, especially for horses. It is an esterified form of boldenone, acting as a long-lasting prodrug that is administered by intramuscular injection. The drug exerts its effects by binding to the androgen receptor, leading to increased protein synthesis and muscle growth through gene transcription regulation. Boldenone undecylenate has strong anabolic effects with moderate androgenic activity and weak estrogenic properties. It was originally introduced for medical use in the 1960s but is now mainly used in animals to promote weight gain, improve appetite, and enhance physical condition following illness or overexertion. Human use has been discontinued due to side effects such as masculinization and its status as a controlled substance; it remains marketed for veterinary purposes in some countries[1][2][5][6].
