Universal Nutrition - Isostak Nutrient Partitioning Supplement - 60 Capsules
Universal Nutrition IsoStak is a super anabolic flavone complex that contains 7-isopropoxyisoflavone, 5,7-dihydroxyflavone, 20-hydroxyecdysone, isoflavonol, and triboxybol. IsoStak can help you grow, naturally. That's why IsoStak can be safely used by those athletes who want to avoid side effects of prohormone-based products.
For natural bodybuilders the world over, the Holy Grail would be a natural alternative to anabolic steroids. Steroids, after all, are highly anabolic. They can increase anabolism through protein synthesis, promoting a positive nitrogen balance, and reducing muscle wasting.
There are obvious disadvantages: steroids are illegal and they can cause permanent side effects including hair loss, prostate enlargement, gynecomastia, testicular shrinkage, acne, and liver damage among others. So for decades, researchers have been seeking a legal alternative. When prohormones hit the supplement scene, the wait seemed over. Prohormones had the ability to directly convert to anabolic hormones like testosterone. However, prohormones were not natural. Furthermore, they were soon banned from many organized sports bodies like the NCAA. So drug-tested athletes and natural bodybuilders had to wait for a viable legal and natural (prohormone-free) anabolic. Until now.
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. What makes IsoStak different is that it can pump nutrients and calories selectively into growing muscles for maximum mass, rather than increasing bodyfat stores. Very impressive.
