is it really necessary to take 2.5 mg of letrozole daily to reverse bitchtits? i just finished my PCT. going to take letrozole till my bitchtits are reversed. Ive read that it takes as few as 20 micrograms to produce a notable estrogen diminution. im afraid that by taking letrozole at 2.5mg itll take more than a month after discontinuing before the remaining quantity stops blocking my oestrogen.....
