Equipoise Side Effects : 

The side effects of Equipoise are mild. The structure of boldenone does allow it to convert into estrogen, but it does not have an extremely high affinity to do so. If we look at aromatization studies, they 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 Equipoise, 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, Femara, or Amonasin would be a stronger option, however probably not necessary with such a mild drug.

Equipoise is not a rapid mass builder, but will provide a slow but steady gain of strength and quality muscle mass. The most positive effects of this drug are seen when it is used for longer cycles, usually lasting at least 10 weeks in length. The muscle gained should not be the smooth bulk seen with androgens, but instead a very defined and solid look. Since water bloat is not contributing greatly to the diameter of the muscle, much of the size gained on a cycle of Equipoise can be retained after the drug has been discontinued.

It is interesting to note that structurally Equipoise and the classic bulking drug Dianabol are almost identical. In the case of Equipoise the compound uses a l7beta ester (undecylenate), while Dianabol is 17 alpha alkylated. Aside from that difference, the drugs are basically the same. Of course they act quite differently in the body, which goes to show the 17-methylation effects more than just the oral efficancy of a steroid.
