Trenbolone Acetate is the most powerful overall steroid in use by bodybuilders today. Tren, as it is often called, is both highly androgenic and anabolic. It is chemically unable to aromatize, and therefore produces no estrogen buildup. This, along with its high androgenic properties, makes the muscle produced by this drug very hard and defined.
