this is dumb. saw palmetto spikes testosterone because it blocks DHT, an androgen far stronger than testosterone (it also cannot be aromatized into estrogen like testosterone can)
testosterone can be converted to estrogen if it is free in the blood, but DHT actively inhibits estrogen if it is in the blood. that is why trannies take an anti-androgen. Saw palmetto is simply a ghetto anti-androgen. this is also why people on hair loss products (finasteride) get titties (fin is an anti-androgen)
It puts stress on your liver, which is why it should be taken in normal amounts (no more than 4 pills a day of berry). normal dosages from studies reduce serum levels of DHT around 25-30% (better than nothing but less than finasteride or dutasteride).
as for PM, even though its an insanely estrogenic root, it is still weak in comparison to HRT. Men in Thailand that use PM for transitioning take 4-5 grams per day (they get results, but i think that might be a little too much).
I personally take 2,500mg PM per day (ramped up from 1,500) as i feel that's my limit before I get really cloudy-headed and my heart rate goes up.
any man pounding more than 1,500mg of PM should be walking every single day. this is extremely important (mtfs and anyone on estrogen are at higher risk of blood clots killing them, trannies are monitored very closely for them)
1000mg of SP berry + 2500mg of PM every day (three day break per month and a couple missed days) has been my dosage for the past 3 months now. everything is going pretty smoothly (although im 5 inches taller and i weigh about 60 lbs more than you, you might want to ramp slowly)
anyway, hope that clarified some of the points. if you start feeling ill, you'll know to cut back.
