Unlike other over the counter test supplements, AGGRO™ is backed by real human research. In one study, test subjects taking just one of the 11 ingredients found in AGGRO™ increased testosterone by over 40% when used as directed! These subjects also increased Luteinizing Hormone (LH) which regulates the expression of 17-β hydroxysteroid dehydrogenase, an enzyme which converts androstenedione into testosterone. In another study, researchers at Western Washington University gave Zinc, Magnesium and Vitamin B-6 to a group of NCAA football players working out twice daily. After 7 weeks of testing, they found a significant increase in testosterone and growth hormone. AGGRO™ delivers the exact same dose of Zinc, Magnesium and Vitamin B-6 used in this breakthrough study!
