I take 1mg Finpecia and have no issue surrounding its legitimacy. Proscar is the same drug just 5mg which you need cut into 5ths to get 1mg dose. If you get on the meds make sure they are from a legit source.
If you want to stabilise your loss and get proactive then defo worth considering.
I am in the UK and get my Finpecia from this reliable source - Dr Singh http://ukfinasteride.info
