Femara (letrozole) is an adequate anti-aromatase.
I have found that it supressed my libido, however. I ran some similar cycles where the only real change was from femara to arimidex, and libido has not been a problem since, so I am fairly convinced that it was the culprit.
Femara does this BECAUSE it is such an efficient AI. More powerful than arimidex at eliminating E. Some E is necessary for a healthy male sex drive and femara AKA Letro will suppress almost all E.
So is it the best choice for just doing cycles and getting big? Maybe not, but if trying to get super hard, dry and grainy it works quite well, who has time or energy for sex while prepping for events anywho?
An example of my recent experiance with it (Letro): During event prep I noticed at about the 7 week out point that I still seemed to be having Estrogenic sides, was not really sure if I was just still too fat or if E was having me hold fat and water. Was on a very low dose of letro at the time about a 1/2mg ED, average dose while on a significant cycle for letro is about 1 3/4mg ED, this dose will knock down E levels big time (if anyone ever has gyno problems starting I would recomend that dose to correct it ASAP).
So I decided to up the letro dose from 1/2mg ED to 1 1/2mg ED, bingo! it was a wise move as after that I blasted past weight loss sticking points with little effort. It was like night and day. But bye, bye libido and sweet emotions which was probally a good thing at the time.
