I am talking about avoiding the crash that could happen when you stop, since I couldn't find anyone complaining about pfs after using duta, maybe because it tapers off with its long half life.If you get sides from Finasteride which blocks less DHT than Dutasteride, and keeping in mind the blocking of DHT is the main cause of side effects, most people who do get sides in Finasteride are likely to get sides from Dutasteride as well, if not worse. But not everyone.
