Where do you guys get your Propecia from?

[Britannia]

Im sure this gets asked alot but I really would appreciate you guys letting me know where I can get genuine Propecia from online. Theres so many sites Im sure some must be selling counterfeit pills. Theres a warning on the Belgravia website about counterfeit propecia on the net.
If any of you finasteride users could tell me where you buy it from it would be much appreciated.
