Question for anyone who might have come across this stat anywhere on their pursuit for answers.
How many Propecia users are there in the UK ?
If anyone can find the answer with good authority from a reliable source then i will gladly buy them a beer and send them a copy of my book

have you tried emailing Merck (or maybe Boots) and asking for their sales figures?
of course that won’t include those of us who take the generics though
