First of all, there are many different theories on how much & how long to take the clomid, but arimidex is fairly easy. Arimidex- just start out with about 1/4 a tab ed or eod, or 1/4 cc of the liquid stuff. If that doesn't work for you then up the dosage until you get it right. Clomid- Here's what I do.....I calculate approximately when the AS I was using should be clearing my system, and then I take 200mg or 300mg the first day. Then I take 100mg ed for 5-7 days. Then I finish off with 50mg for another week, or longer if I don't feel back to normal yet.
