Afaik it is still unknown in which way tren can be affected by 5ar.

But it is possible that tren can not be reduced by 5ar to DHT like you said.
19-nortestosterone on the other hand is deactivated by 5ar and 7-alpha-methyl-19-nortestosterone can not be altered alltogether.
So it is still unclear if tren follows a similiar pathway but it was clearly demonstrated that tren has in fact a lower androgenic activity in prostata cells than test. This is all good in my book.

If someone is interested in reading the whole study i'll post a link here:

on a side note: i have never used tren, but most of my buddys have. So there was only 1 person who had hair loss problems, but he also used the tren with test. Moreover none of my buddys got acne or prostata problems.
+ keep in mind that it is also possible to loose hair from deca IF you are prone to MPB. ...
