hyperprolactinemia
"It has reduced my prolactin levels effectively, and it increases testosterone to some extent.  The side effects are loss of motivation, and finding mental exertion more tiring, which can be a real problem at work.  The side effects seem to be dose dependant so I break the pills into quarters or eighths and take them more often to eliminate the peaks after dosing. I've also been able to reduce the dose whilst still keeping the prolactin levels in the middle of the normal range, which has also helped with side effects."
