Sorry if I came accross as a know-it-all for my first posts on this board, I should keep an open-minded attitude and keep questioning everything I "know", no matter how surprising a practice first appears to be.
For my personal case, laying off gluten and eating a diet that is richer in protein and lower in carbs has me feeling a lot more energetic and mentally clear.
I used to have brain fog, and that typical after-meal lethargy.
When it comes to hormone, what I've learnt and what I've experimented lead me to think that any exogenous introduction will dictate that your body downregulate by so much.
In the case of DHT, we know that it exerts a positive feedback loop on the 5AR enzyme, but the downregulation will come at the testosterone level.
Also, I don't know which amount will lower your estrogens to the point you feel it, but I definitely felt it.
It's good to go by how you feel when experimenting, also remember to get blood drawn at some point to confirm your feeling
Very respectable post.
