Sarah, for an anti-androgen, I use Siterone. I break a 50mg tablet, and take a half tab every 2-3 days, usually at bedtime. I probably don't need it, but I still have enough left to take me thru our current PM supply. When it's gone, it's gone. It's more a case of "waste not, want not". SP disagreed with my stomach, and seemed to decrease my ambition. Maybe the ambition loss was a sign that it was working, as it could be a symptom of low T, but the nearly nauseous feeling it gave me overruled any other usefulness. And, I only took 2/day. While the dosage of Siterone is quite low, when combined with my already extremely low T, it keeps the DHT low enough to let PM do it's job unmolested. I'll see what happens later when I go to only PM and no antis, but that's little ways off yet. Patti
