The average value in young men is ca. 550 ng/dl.
I have never taken letrozole, however, although I plan to buy some, because I have difficulties with hard testosterone suppression during cycles. Some guys claim that it negatively influences mood and joints due to extreme estrogen suppression. Personally I think that it won't be so dramatic, because even after 2-3 months, estrogen levels are not dramatically low. But you shouldn't take it for a long time, sure.
