Boldenone undecylenate (Equipoise, EQ) is a derivative of testosterone with a similar androgenic activity and higher mytrophic activity. Boldenone undecylenate has a very low conversion to oestrogen and hence does not present excessive oestrogen side effects. Instead, boldenone undecylenate is converted by 5-alpha-reductase into dihydroboldenone and some of its androgenic effect mediated by dihydroboldenone.
Boldenone undecylenate increases overall body metabolism rate and increases appetite. Its primary purpose is to increase red blood cell count whilst increasing lean body mass. Since Boldenone offers very few side effects it makes this anabolic/androgenic steroid (AAS) a good therapeutic choice for competitive athletes, bodybuilders and age-related non-genomic muscle degenerative diseases like sarcopenia. The undecylenate ester extends half-life of boldenone in circulation, which, depending on dose, is approximately 10 days.
