I don't think I've heard of anyone using femara w/ clomid instead of nolvadex or arimidex. I've heard it works better than the two, but I don't know much about it. Does it suck? Hard to get? Expensive?
Femara is a really good inhibitor of estrogen, but is considered by some too powerful of an inhibitor. Inhibitors can't always distinguish between estrogen and other things so sometimes they end up blocking helpful material.
all in all it will work but i would try and stick with ari or nolva depending on if you are afraid of bloat of not.
I agree with healer about strength of Femara. I also talked to someone who had a rebound after using it. There is a study that shows Nolva and Femara interact due to chemical nautre of the molecule, it reduces Nolvadex effectiveness by 40%.
