Click Label To Enlarge CHRYSIN XS The NEW Chrysin-XS™ by SPORTS ONE® is a revolutionary aromatase inhibitor. The Chrysin-XS™ proprietary formula was developed by combining naturally occurring aromatase inhibitors and inhibitors of the action of SHBG. The primary active ingredients in Chrysin-XS™ are Coumesterol and Chrysin. Chrysin-XS™ does not exert its action through any direct hormonal or prohormonal activity (androgenic or estrogenic). Chrysin-XS™ is a multi-pathway formulation that minimizes or eliminates the undesirable effects associated with an estrogen dominant environment. Chrysin-XS™ maintains the correct testosterone to estrogen ratios that yield the benefits associated with normal estrogen levels. Chrysin-XS™ acts as an irreversible anti-aromatase agent and is thus a powerful elevator of total testosterone and maximum liberator of free testosterone. Chrysin-XS™ may also play a role in long-term selective estrogen blocking and/or inhibition of selective estrogen signaling. Chrysin-XS™ may contribute to notable improvements in muscular growth and fat loss, in addition to its wide array of health and anti-aging benefits. SPORTS ONE® Chrysin-XS™ is more natural, more effective alternative for traditional testosterone hormone replacement therapy.
