MRM, Chrysin 500mg (Flavone X), 30 Capsules. MRM Chrysin 500, also known as Flavone X, is structurally defined as 5, 7-dihydroxyflavone. MRM Chrysin 500 maximizes testosterone concentration, supports lean muscle mass, and enhances strength gains. Human tissue experiments with this monoflavone demonstrated the ability to limit aromatase activity. Aromatase is an enzyme that is found in various tissues within the body and is responsible for the conversion of androstenedione and testosterone into estrogen. This conversion is utilized by the body to keep Testosterone: Estrogen ratios in balance. When athletes are in quest of increasing lean body mass, maximizing serum testosterone levels is of paramount concern. European Olympic athletes report receiving benefit from using 1-3 grams per day. Anecdotal reports indicate that Chrysin works best when taken in conjunction with DHEA, Tribest, and TribuPlex.
