Does not destroy any DHT. It reduces conversion of T–>DHT.
So that might increase FT. But you need HDT for androgenic and libido effects. When drugs are taken that [strongly] reduce DHT, sex drive can be reduced.
It does not aid in prostate health, but helps once the prostate gets to be a problem from enlargement or cancer. As men age, and T goes down and E goes up, it is thought that the E is a driver of prostate enlargement, not T. Case in point, young guys with lots of T and DHT do not get these problems, it is guys with low T and high E that are vulnerable.
So in the long term, stay slim as fat promotes/performs T–>E conversion. Deal with E if it becomes an issue.
I have wondered about guys in the middle. Perhaps AI, alone without gear, would be good for health and training needs. Might help libido in some cases as well. Someone in that category should try arimidex and report back.[/quote]
