if i choose to use one of those should i go for femara or aromasin? i mean during xyxle and pct
or use femara during cycle and aromasin on pct?
which one will be best to look more ''dry''?
thanks
I have no personal experience with aromasin, which is recently becoming popular as a PCT compound.  Some on here like femara (letrozole).  I have used it, and thought it had a negative effect on my libido.  Due to that, I now use arimidex on-cycle.  
Best answer would be to try femara, and see what YOU think, as we all seem to respond differently.  Good luck with your cycle.
