I'm going to be taking Finasteride soon for my hair but I don't want to get gynecomastia so I plan on taking the aromatase inhibitor Letrozole with it. I'm a little confused because I have read that doses as little as .25 mg can eliminate 98% of estrogen, an I've also read that 2.25 mg will reduce estradiol by 40-60%...
So, how much Letrozole should be taken to combat the increase in estrogen from Finasteride? Also, where does AR-R ship from?
