IsoStak is a test booster utilizing 5-methyl-7-methoxyisoflavone. 7-isopropoxyisoflavone. 5,7-dihydroxyflavone. 20-hydroxyecdysone. Isoflavonol®. Triboxybol®. These are some of the latest bodybuilding ingredients. Alone, each packs a punch. Together, they're part of IsoStak, a super anabolic flavone complex. While you may not be able to pronounce these substances, know this: IsoStak can help you grow. Naturally. Without steroids or prohormones like andro and 19-norandro. 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. IsoStak is important for several reasons. Prohormones are powerful anabolic substances. When used, there's a potential for androgenic side effects similar to mild steroid use. Because of its unique formulation, however, IsoStak can be safely used by those athletes who are concerned with these side effects. In addition, with prohormone use, there's always a possibility for a false-positive steroid drug test (prohormones are direct precursors to testosterone and nortestosterone). IsoStak is a better choice for drug-tested athletes. Finally, IsoStak offers one distinct benefit not found in a strict prohormone supplement: nutrition-partitioning.

Hi Alex. It doesn't say on the usage directions but with any test booster i suggest a 2 months on/1 month off rotation.
