Best Place to Buy Proscar in the UK and Switching From Proscar to Propecia - Safe?

[ohlife]

Hey guys,

Just wondering if anyone could tell me the best place (reliability and cost wise) to buy proscar from in the UK? If not, then Propecia?

Also, are Proscar and Propecia the same, and would it be of any significance changing from Proscar to Propecia after a while?

Thanks!
