Femara vs Arimidex

[KAEW44]

could someone tell us the difference and compare effectiveness of both when running during a cycle as an anti-estrogen-aromatase. Thank you

Um... huh?
You mean as an aromatase inhibitor.

Letrozole is typically more expensive.
Letrozole is marginally more effective.
Letrozole is known to shut down libido.

IMHO, it's not worth the extra money.
I'll stick with anastrozole.

a-dex or anastrozole causes libido problems too!!

Letro raises igf-1 where as a-dex lowers it.

Actually Adex has been shown to raise IGF-1 too.
Adex and letro are pretty much identical in that everything adex does, letro does too, but does it to a slightly greater extent

Also Letro and Nolva don't get along together very well.

Dude...pick up the latest MD...there is a good article on this.

Product Effect on igf-1 percentage
Femara/Letrozole increases igf-1 24%
Arimidex/Amastrozole decreases igf-1 18%

They do this with all of the popular anti-e's.

They even break down the relative potency of type 1 and type 2 inhibition:

product aromatase inhibition residual aromatase (%)
a-dex 96.7 3.1
letro 98.7 1.3

Its a good read.

They're pulling a Llewellyn. There have beenn several studies on Adex and letro.....they simply chose to use the one study that showed an IGF-1 decrease for Adex and not the ones that show an increase. Selective citation is about the laziest and most irresponsible thing there is. Adex and letro work in identical fashions/mechanisms, competitive inhibition of aromatase. therefore, all of the resulting physiological effects will be in the same direction, but with different magnitiudes (e.g. letro reduces estrogen by 90% but Adex does so by 85%, letro reduces HDL by 35% but Adex reduces HDL by 25%, etc)

letro seemed to shut my libido down alot more than l-dex and letro seemed alot
harder on my body and from what I read it's harder on you than L-dex, I would run
L-dex you can run it right though PCT to...It's supposed to make a nice
combo with nolva and clomid for pct...and as sv-1 metioned letro and nolva
counteract eachother.

If einstein sais theyre similar...then they are....PERIOD!
