Winny thinned my hair like crazy. Strangely enough, Propecia (Finasteride) at 1 mg a day didn't do a darn thing about it either.
Propecia works wonders on me when I'm on test, but then again I read something that Propecia stops the converstion of Test to DHT and since Winny is already a DHT-derivative, the Propecia can't stop it. Is any of that true?
