Athletes and bodybuilders have been using trenbolone acetate as a physique- and performance-enhancing drug for decades. There are a large number of benefits as a bodybuilder through using trenbolone acetate as an AAS, because it is estimated to be approximately five times more effective and stronger than testosterone. Unlike testosterone, trenbolone acetate does not cause any fluid retention while gaining muscle mass. This allows bodybuilders to appear leaner, and this is why it is more commonly used whilst preparing for competitive events. Trenbolone acetate does not convert into an estrogenic metabolite, and this results in a lack of estrogenic side effects.
