Below is what I have read when searching between the two. What do you guys think?

Nolvadex is by far superior for women. Women are different then men in that they have very little conversion of testosterone estrogen. Arimidex does not block the estrogen receptor it simply prevents the aromatization from occuring in the first place (aromatase inhibitor). Thus little aromatization equals little help from an aromatase inhibitor. Tamoxifen on the other hand is a SERM...much different. Because women already have much higher levels of naturally occuring estrogen we need to be able to control these levels. Using Tamoxifen will in essence render the present estrogen somewhat inert because the estrogen receptors will be blocked via the competing tamoxifen.
Women get great results from Nolvadex the last 8 weeks out from a contest. 10mg taken twice daily 8-10 hours apart. Ive seen some dramatic changes once a female client has started Tamoxifen...womens ability to drop stubborn estrogen related fat improves greatly.

Remember Nolvadex is a Selective Estrogen Receptor Modulator which works much differently then Aromasin/Arimidx/Femara which are Aromatase Inhibitors. SERMS are actually weak estrogens that bind to the estrogen receptor and thus prevent estrogen itself from binding and doing its job...hence the associated sides. AI's on the other hand reduce the aromatase enzyme which is necessary for the conversion of testosterone to estrogen...by reducing aromatase less estrogen is created and thus less sides. The key point here being that with women not much test is produced to begin with and thus there is not much conversion...as well the AI has little effect on endogenous estrogen production. This is the reason for using Nolvadex vs an AI...no more than 8 weeks is prudent because there will be an inherent rebound from the excess estrogen in the blood stream.
