Is this true?

Basically the doctor in this man's story said that if you go off Avodart / Dutasteride once taking it, Propecia / Finasteride won't have any effect on you anymore. I wonder what the truth in this is? Anyone with experiences?

I've never heard that before, and i've been about a bit. sounds like nonsense to me.
