Boldenone undecylenate Chemical Properties,Uses,Production
Description
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.

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.

Boldenone is a steroid hormone which has androgenic activity. Androgens bind to the androgen receptor, which regulates gene transcription.
Side effects
