Universal Nutrition IsoStack is a super anabolic flavone complex that contains 7-isopropoxyisoflavone, 5,7-dihydroxyflavone, 20-hydroxyecdysone, isoflavonol, and triboxybol. IsoStak can help you grow, naturally, without steroids or prohormones like andro and 19-norandro. That's why Universal Nutrition IsoStack can be safely used by those athletes who want to avoid side effects of prohormone-based products. IsoStak can help support testosterone production endogenously, prevent aromatization (estrogen conversion), increase the number of androgen receptor sites (by up to 63%), promote protein synthesis, inhibit muscle breakdown, suppress cortisol, and selectively shuttle nutrients into growing muscles.*
