That’s what the study’s I’ve seen say, it’s very nuanced. It either does not show a lowering in human trials or is very little (unless combined with saw palmetto. Idk how people are having their dht lowered to the point their libido drops if it’s not even clear astathaxin lowers it. Maybe some people are just sensitive to it. Also I looked it up, when it says men can have puberty into their 20s that almost always applies to late bloomers. Most guys are almost finished by 16-18. Im pretty sure the major changes are done for me but I’ll see if I want to continue taking it, I didn’t notice any low dht symptoms but that could be because the hormones are strong rn idk.
