i just ran across an article about how the enzyme cytochrome P450 is one of the main steroid destruction pathways in the body. why is this important? because the herb st johns wart is commonly known to enhance the efffect of this enzyme and has been linked to women getting pregnant when thier BC pill's pregesterone has been inactivated too fast. well, this stuff will also work against anyone artificially enhancing the body's testosterone levels.
moral: don't take st johns wart and juice!
just a heads up... that is all
