we were taught in medical school that finasteride blocks the conversion from testosterone to dihydro testosterone and that's it that's all we were told but that is only one fraction of the story because each one of those steroids then goes into something called a neurosteroid right so F DHC goes into Ander andol that's the neurosteroid then you multiply that by six so six steroids are blocked and those six steroids then have a decreased conversion into their neurosteroid sorry the six steroids are blocked because five Alpha reductase acts on more than one exactly steroid cor uh pre progesterone aldosterone uh you can look at there's a whole linear it's not just testosterone
