Are we sure high serum DHT is so desirable? I think what is desirable is testosterone converting into DHT when needed, like in the muscle or in the brain, instead of being chronically elevated in blood. When I was using 250mg test with 10% homemade DHT serum in DMSO, I found DHT to be stimulating and calming at the same time. The calming effect definitely wasn't strong, like that of t3, while the stimulating effect made controlling my thoughts very difficult. Given that I do suffer from stuff like OCD, rumination, adhd, maybe the dht just exposed underlying weakness, but I think good balance is key.
After all those experiences, I'm 100% sure the most important thing is having perfect mental health. If mental health and external stressors are not a problem, achieving optimal energy efficiency through thyroid and androgens is very easy. I think that is why I see many people in the gym abusing heavy androgens and still looking... not so masculine. But in the past if you look at male models from the 60's-80's and if you look at western movies you see that the men have a very unique look to them, a leathery face that looks very appealing, different from old-sunburnt skin.
There is no way into faking that look except making sure mental/spiritual health is 100% on point, after which you can introduce androgens/t3 to get your body used to a new setpoint/homeostasis.
Like most of my posts I'm all over the place, but tl;dr is that bloodlevels mean nothing, what matters is that it reaches tissue. Most bloodlevel increases of dht will simply rise tissue-estrogen as a coping mechanism or introduce various other difficulties. But I did read boron and butea superba work very well for increasing serum DHT.
