7. Other Information

7.0 Description: Average dosage of Boldenone Undecylenate is 300-500 mg per week for men and 50-100 mg per week for women. The injection should be administrated at least once every week and the length of a cycle is varies from 7-8 weeks to 10-12 weeks. Side effects are mild and occur in mainly in cases of high dosages. Athletes may experience acne, oily skin, hair loss, diarrhea, hypertension, prolonged blood clotting time, increased libido as well as post-menopausal bleeding, increased sex drive, swelling of the breasts and virilization symptoms in women.

7.1 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.

7.2 Chemical Properties: Yellow Oil

7.3 Uses: Boldenone Undecylenate is an anabolic steroid developed for veterinary use.

7.4 Brand name: Equipoise [Veterinary] (Fort Dodge Animal Health).

7.6 体内研究: Rabbits were injected intramuscularly twice weekly for two months. BOL had no significant effect on the bwt and bwt gain. Testes and epididymis weights were decreased significantly in the BOL-treated groups. BOL caused significant reduction in serum testosterone level, seminal volume, sperm motility, and sperm count [1].

7.7 Originator: Boldenone undecylenate,Shandong Xinfa Pharmaceutical Co., Ltd.

7.8 Manufacturing Process: 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.

7.9 Therapeutic Function: Anabolic

7.10 Veterinary Drugs and Treatments: Boldenone is labeled for use as adjunctive therapy “. . . as an aid for treating debilitated horses when an improvement in weight, haircoat, or general physical condition is desired” (Package Insert; Equipoise?—Fort Dodge).
Boldenone may possibly be useful to stimulate appetite in cats.
