> The special difference between [[testosterone]] and DHT is that [[testosterone]] is easily aromatized into estrogen, and DHT isn't. There are several ways that the body can dispose of estrogen, but I haven't heard of that way of inactivating it; I don't think it happens in the body.' > I think it was the drug industry, thinking of villains [DHT=BAD] to justify their otherwise crazy treatments. > I haven't heard of any bad effects from DHT, but that might be because it's so rarely used. The liver problems I've heard about have always involved slightly modified molecules. I think the tendency to take too much might be a problem with androgens generally--4 milligrams of [[testosterone]] and 15 mg of [[DHEA]] is a normal daily production for young men, and half of that amount is effective for middle aged men, unless the problem is something else.  > A little DHT should be safe, but I don't think mesterolone is safe in any quantity.
