It really doesn't work that way statistically as mentioned. I often hear that reasoning about using finasteride and duta together to reach say 160 percent chance of no DHT but hell, it's covered by insurance and I have absolutely no sides from both finasteride and duta, well except it turned me transgender, right. finasteride might do other things that help and maintain growth besides eliminating DHT since so many guys say that finasteride/Duta cause tits.
Anyway,
Good Luck,
