The majority require some E2 control = downregulated 5ar

Our bodies are dumping what it considers excess T into (almost entirely) E2, instead of mostly DHT. For most of us, it was the opposite way around before using finasteride. Our bodies are reacting to our normal T as if we were on high doses of steroids.

If lab results weren’t enough, this demonstrates downregulated 5ar enzymes (ie. not returning to baseline which was also demonstrated in studies).

Temporary fix: increase metabolic rate + AI

I don;t like this for several reasons:
While optimizing metabolic rate is always wise, a high metabolic rate is not always possible to maintain 100% of the time and so an AI is necessary with downregulated 5ar enzymes.
There are other implications on downregulated 5ar: ED, low libido, venous leakage / peyronies, decreased virilization, gyno prone, imbalanced neurosteroids (low dopamine, low allo), and much more. Basically all the sides of a 5ar inhibitor

The real solution is to upregulate our 5ar enzyme. We need to hire a researcher full time to work on this.

My neighbor is in 5mg of fin and he is totally fine. He has blocked 5ar. Why is he not getting PFS if PFS is related to 5ar down regulation?

Why does it take many of us months or years to crash? 5ar downregulation happens within the day of taking fin.

pfs is in your head.
