I have been on finasteride for 16months approx. I started taking the Merck brand propecia straight from walgreens or CVS. At first 1 or 2 month mark i noticed less hair falling out and my hair to be thicker. After that I started shedding. Recently w/in the last 2-2.5 months i have been shedding the most i have ever shed in my life. i mean everyday constantly. my hardwood floors have to be swept many times a day. Also over the summer i started using Dr.reddys Finast (cutting into 1.25 mg pills as best i could). I used this for two months than got a bit nervous that it wasnt legit (i dunno remember way, probly a mental thing) so i got a Proscar script and have been using it ever since, until a week ago when i decided to quit due to shed, etc. So im thinking about maybe going on dutasteride, but i dunno. obviously im a bit nervous to start it....
