Chrysin is a natural aromatase inhibitor extracted from the plant Passiflora coerulea which prevents the conversion of testosterone into estrogen. This is useful in treating high estrogen levels and low testsosterone. Chrysin is poorly absorbed if taken orally, even when used with penetration enhancers, so our laboratory has developed a liposomal gel base which provides good transdermal absorption when applied to your skin. DOSE: 1 to 3ml applied daily which equates to 100mg to 300mg of chrysin. More information on chrysin is available here.
