Stanoplex 20 is a brand name for the anabolic steroid Stanozolol or also know as Winstrol. This compound is a derivative of dihydrotestosterone, although its activity is much milder than this androgen in nature. It is technically classified as an anabolic steroid, shown to exhibit a slightly greater tendency for muscle growth than androgenic activity in early studies. While dihydrotestosterone really only provides androgenic side effects when administered, Stanoplex 20 instead provides quality muscle growth. The anabolic properties of this substance are still mild in comparison to many stronger compounds, but it is still a good, reliable builder of muscle.
