Description
Boldenone undecylenate is an androgen and anabolic steroid (AAS) medication which is used in veterinary medicine, mainly in horses. It was formerly used in humans as well. It is given by injection into muscle. 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. Boldenone undecylenate is an androgen ester and a long-lasting prodrug of boldenone in the body. Boldenone undecylenate was introduced for medical use in the 1960s. In addition to its medical use, boldenone undecylenate is used to improve physique and performance. The drug is a controlled substance in many countries and so non-medical use is generally illicit. It remains marketed for veterinary use in Australia and the United States.
Medical use
Studies conducted in laboratory animals to evaluate pharmacological activity characterized boldenone undecylenate as having distinct anabolic properties together with a certain degree of androgenic activity. It does not have marked antigonadotrophic properties, nor does it produce any clear-cut effects on the endometrium, conditions that are commonly observed when similar substances are used.
In clinical trials at the recommended dosage, boldenone injectable had a marked anabolic effect in debilitated horses, appetite improved, weight gain was noted, vigor increased and improvement was noted in musculature and haircoat. This would be expected with an anabolic agent such as boldenone injectable, particularly where there had been marked tissue breakdown associated with disease, prolonged anorexia or overwork.
