Blood test results

Guys I really need your help here. I was on Proscar first, and then Propecia for most of the last decade. During recent years I also was on Dutasteride at the same time as well.

I quite all drugs about 6-8 weeks ago after having an inredibly low libido including erectile dysfunction.

This is my most recent blood work below. Can anyone please comment on the DHT levels? And realistically what should they be in a healthy male in his mid 30s?
