Another advantage to using Superdrol is that it does not turn into estrogen. Many prohormones available start out as a testosterone-like substance in the body, but then eventually turn into estrogen through a process called aromatization. Estrogen causes decreased strength, muscle loss and fat gain. Thus, it is a promoter of the exact opposite traits someone who is taking Superdrol would want. These characteristics arise after one stops taking the compound. With Superdrol, however, the aromatization process never starts. The compound does not turn into estrogen in the body, meaning much of the muscle gain and fat loss one experienced while taking it will remain after dosing concludes.
