Universal Nutrition's ""X"" Factor may be bodybuilding's best kept secret. Due to poor diets, the enviroment and genetics, all the hard-earned testosterone your body produces through training and supplementation can be converted to estrogen, the female sex hormone, through chemical synthesis known as aromatization. With our revolutionary new Chrysin X, you can put and end to it once and for all. Chrysin X contains the active ingredient 5,7-dihydroxyflavone which inhibits cytochrome P-450 aromatase activity. Chrysin X also contains other ingredients designed to block of the conversion of testosterone into other negative compounds such as DHT. If you want to maintain your levels of testosterone, use Chrysin X. It provides natural testosterone support as well as powerful anti-aromatase, anti-viral & anti-inflammatory actions.
