Boldebolin by Alpha Pharma or Equipoise as it is more commonly known, is a steroid compound that can give users slow but steady gains during a cycle. It is also relatively safe with very few reports of the side effects caused by Testosterone conversion into estrogen. For bodybuilders, it should be used with Testosterone as Boldebolin can cause sexual dysfunction. Boldebolin’s long-lasting ester means it should be used for a minimum 12-week cycle.
Boldebolin is the popular brand name for the veterinary injectable steroid Boldenone Undecylenate. It is a derivative of testosterone, which exhibits strong anabolic and moderately androgenic properties. The Undecylenate ester greatly extends the activity of the drug (the Undecylenate ester is only one carbon atom longer than Decanoate), so that clinically injections would need to be repeated every three or four weeks. In the veterinary field Equipoise is most commonly used on horses, exhibiting a pronounced effect on lean bodyweight, appetite and general disposition of the animal. As with all steroids, this compound shows a marked ability for increasing red blood cell production. In recent years this compound has become a favourite among athletes. Many consider it an ideal replacement to Deca-Durabolin.
The side effects from Boldebolin are generally mild. Although the structure of Boldenone does allow it to convert into estrogen, it does not have an extremely high affinity to do so. If we look at aromatization studies, they suggest that its rate of estrogen conversion should be about half that of testosterone’s. Water retention with this drug would therefore be slightly higher than that with Deca-Durabolin (with an estimated 20% conversion), but much less than we would find with a stronger compound as Testosterone. While there is still a chance of encountering an estrogen related side effect as such when using Boldebolin, problems are usually not encountered at a moderate dosage level. Gynecomastia might become a problem, but usually only with very sensitive individuals or (again) with those using higher dosages. If estrogenic effects become a problem, the addition of Nolvadex should of course make the cycle more tolerable. An anti-aromatase such as Arimidex or Femara would be a stronger option, however probably not necessary with such a mild drug.
