In other words, DHT is needed to mature men, but some men don't have theirs turned down as they “should.”
It doesn’t sound right to me. As far as I know it is still produced and useful in the body but I guess it drops off with testosterone production since it is produced from that. It makes facial and body hair grow and I also read some studies where it improves mood, anxiety, confidence, etc in men — basically making them mentally manlier. There are other claims about it making athletes stronger and more “aggressive” or determined or something in the context of their sport but that gets a bit anecdotal.
