I asked the same question and confirmed that is has a positive feedback loop just like pregnenolone does meaning it stimulates it's own synthesis instead of negative feedback loop causing shutdown. Not many hormones in the body have a positive feedback mechanism. So it would help fix the underlying problem, which is awesome and what we want.
Also, let me add that this isn't only mental, it's physical too, I feel harder all around and my joints are tight and I'm more vascular. So it's physical too. It increases endogenous DHT along with decreasing both estrogen and prolactin (circulating and receptor level)- no need to cycle it, your not shutting down anything in your body, but actually increasing it or restoring to homestasis.
Just like exogenous DHT can increase the body's own natural synthesis of DHT.

Check this link out where I asked it (post number 116) about the positive feedback mechanism.

The studies I have seen show that 5a-DHP stimulated both progesterone synthesis and its own synthesis via 5-AR. So, that is the positive feedback mechanism. The last of negative feedback is a bit more speculative as it has not been tested extensively in vivo, but the few studies on mice and rats did not show 5a-DHP inhibiting any other hormones except estrogen and prolactin. So, at worst it is not inhibiting DHT/T production and at best it may raise endogenous DHT levels.
