What will hardcore bodybuilders be using once the ban occurs? Scifit Nutrition has a good idea of where the supplement industry will be heading once all pro-hormones are off the shelves... in a word TZ3. This is the next step in bodybuilding supplements, youll start to see and hear much more about TZ3 in the following months... We think that TZ3 will be "bar none" the replacement stack for anyone looking for pro-hormone type gains after the FDA ban. SciFit’s triple action TZ3 has been designed as a safe, natural method of supporting healthy testosterone levels. TZ3 is a precise combination of the patented free testosterone increasing ZMA™, the most potent source of the LH enhancing Tribulus Terrestris, and the natural estrogen inhibiting effects of 3,6,17-Androstenetrione
