Chrysin 500 mg x 30 capsules

Chrysin is a compound in the flavone family that is extracted mainly from passion flower plants. Chrysin happens to be a very good inhibitor of aromatase, the enzyme in the body that converts testosterone into estradiol, and androstenedione into estrone. When this enzyme is inhibited, testosterone (as well as androstenedione) will tend to accumulate to higher concentrations.
