Boldenone undecylenate is a kind of synthetic and injectable anabolic-androgenic steroid. It is a kind of androgen ester that can be used in veterinary medicine, particularly in horse. As a synthetic steroid, it has a similar effect as the natural steroid testosterone. Upon treatment of boldenone undecylenate, horses exhibit improved temperament and appetite, further increasing their weight and strengthening the muscles tissues. However, the effect is generally mild. Similar growth promoting effect of boldenone undecylenate has also been observed in goats and calves. The mechanism of action of boldenone undecylenate is acting as a steroid hormone with androgenic activity, further binding to the androgen receptor to regulate related gene transcription. It should be noted, however, the activity of boldenone is mainly anabolic, with a low androgenic potency.

To a solution 5 g of L-dehydrotestosterone in 25 ml of benzene was added 3
ml of pyridine and 7.1 ml undecylene chloride. The mixture was heated for 2
heurs at 70°C. After cooling pyridine hydrochloride was filtered off. The filtrat
was purified via chromatography on neutral aluminum oxide. Benzenic eluate
was concentrated to obtain 1-dehydrotestosteron 17-undecylenate (boldenone
undecylenate) as an oil; λmax 243-244 nm.

With a chemical structure that's nearly identical to testosterone, boldenone can stimulate protein synthesis and the release of erythropoietin in the kidneys. Athletes sometimes use boldenone, which may be sold on the black market, to increase muscle mass and strength.
Boldenone
is a steroid hormone which has androgenic activity. Androgens bind to
the androgen receptor, which regulates gene transcription.
May include symptoms of masculinization like acne, increased hair growth, voice changes, and increased sexual desire.
