I read the following in a good post at MuscleChemistry.com
both arimidex/ldex/anastrozole and femara/letrozole hurt your cholesterol. the way these 2 anti e's work is they inhibit the aromatase enzyme. by inhibiting the enzyme which converts testosterone to estrogen, you reduce or even come close to eliminating estrogen production. we need some estrogen to be healthy. the major drawback to this is without estrogen, your lipid profile gets fucked.
exemestane works differently. it does not stop the body from producing estrogen. rather, it makes it so the estrogen is unable to bind to receptors by deactivating the binding enzyme. if the estrogen cannot bind, you simply will not get bloated or get gyno. the estrogen is crippled due to exemestane. however, since the estrogen is still floating around, it will not negatively affect your lipid/cholesterol profile.
So this to me says that letro and ldex are the ones that can come close to completely eliminating estrogen...........as evidenced by the screwed up lipid panels.
Aromasin, on the other hand, just deactivates the binding enzyme, but does not in the process eliminate the estrogen.
Providing this is fact, would you Bluewizz still agree with what you are saying?
