Boldenone undecylenate is a androgen and anabolic steroid (AAS) medication which is used in veterinary medicine, mainly in horses.
It was introduced for medical use in the 1960s. In addition to its medical use, boldenone undecylenate is used to improve physique and performance. There are many known cases of doping in sports with boldenone undecylenate by professional athletes.
Side effects of boldenone undecylenate include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT).
It has strong anabolic effects and moderate androgenic effects, weak estrogenic effects, and no risk of liver damage.
