Has anyone noticed any patterns with the type/ brand of finasteride used?

I’m sure this has been asked before but has any sort of pattern emerged with regards to side effects and the type/ brand of finasteride used? for example I used FINCAR ordered from inhousepharmacy, this did not require a prescription. Is there less side effects reported with the real Propecia obtained on prescription?

There is no way to know that but since Finasteride is the active ingredient and the molecule synthesized is identical across all brands, it should make no difference wether you took Fincar, Propecia, or some other generic.
