Letrozole is also known as Femara. Letro is 10-30x more effective than Arimidex in it's ability to pass thru the cell membrane of lipid (fat) cells and inhibit the activity of aromatize -- in other words, Letro is far superior in lowering estrogen levels in fat cells. This has two benefits for bodybuilders:
(1) Estrogen 'attracts' water, so less water retention
(2) an average male bodybuilder is around 6-10% bodyfat
That's a lot of lipid cells with aromatase inside them, so a substantial percentage of aromatase is left untouched by Arimidex, due to its poor ability to enter lipid cells. Arimidex is approximately 80% effective at inhibiting aromatase.. letrozole is around 95-97%.
