Letrozole is 10-30x more effective than Arimidex in it's ability to pass through the cell membrane of lipid (fat) cells and inhibit the activity of aromatase -- in other words, Letrozole is far superior in lowering estrogen levels in fat cells. This has two benefits for researchers;
(1) Estrogen 'attracts' water, thus water retention occurs.
(2) A substantial percentage of aromatase is left untouched by Arimidex due to it's poor ability to enter lipid cells. Arimidex is approximately 80% effective at inhibiting aromatase, Letrozole is around 95-97% effective.
