Hi Hanah,
Anti-androgens have disadvantages too: they make you depressed, kill your libido, ruin your ability to cope with stress, and even cause osteoporosis. If you don´t get breakouts and don´t lose hair, you get enough anti-androgen. More will only cause trouble.
The best advice I can give is to continue your experiment. You are the first person I know to use hops and PM together. It may work, because hops is a mood downer, and PM is a mood upper.
Hops and PM are both phyto-estrogens and anti-androgens. SP is a third anti-androgen, and I think this is too much. People on PM get headaches from estrogen dominance, and hops will only make it worse. You will need a lot of FG to make enough progesterone to balance the estrogens. You may have to go to twice as much as hops+PM.
You can also add fennel tea, about a quarter of the amount of hops+PM will do. Fennel is a phyto-estrogen and increases prolactin.
Good luck, and keep us posted.
