Descripción

El Undecilenato de Boldenona es un derivado de la testosterona, que presenta fuertes propiedades anabólicas y moderadamente androgénicas. El éster de undecilenato prolonga enormemente la actividad del fármaco, por lo que clínicamente sería necesario repetir las inyecciones cada 3 ó 4 semanas. En el ámbito veterinario, el undecilenato de boldenona se utiliza con mayor frecuencia en caballos, con un efecto pronunciado sobre el peso corporal magro, el apetito y la disposición general del animal. Como todos los esteroides, este compuesto muestra una marcada capacidad para aumentar la producción de glóbulos rojos. En los últimos años, este compuesto se ha convertido en un favorito entre los atletas. Muchos lo consideran un sustituto ideal del Deca-Durabolin.

The side effects of Boldenone Undecylenate are generally mild. The structure of Boldenone Undecylenate 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 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 Boldenone Undecylenate, 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  would be a stronger option, however probably not necessary with such a mild drug.

Although typically dosage related, Boldenone Undecylenate can also produce distinct androgenic side effects. Oily skin, acne, increased aggression and hair loss are all possible with this compound. Women find this drug quite comfortable, virilization symptoms usually unheard of when taken at low doses. Boldenone Undecylenate does reduce to a more potent androgen (dihydroboldenone) via the 5alpha reductase enzyme (which produces DHT from testosterone), however its affinity for this interaction in the human body is low to nonexistent. Therefore the reductase inhibitor Proscar would not be of much use with Boldenone Undecylenate, as it would be blocking what is at best an insignificant path of metabolism for the steroid. Although this drug is relatively mild, it still has a depressive effect on endogenous testosterone levels, therefore a proper post cycle therapy HCG and Clomid/Nolvadex is needed at the conclusion of each cycle to avoid a “crash”. A waiting time of around 3 weeks is required before starting PCT, enabling enough of the drug to clear one’s system to make PCT effective.

Para mantener estables los niveles en sangre, el undecilenato de boldenona debe inyectarse al menos una vez por semana. La dosis más común es de 400-600 mg por semana para los hombres y de 50-150 mg por semana para las mujeres.
