I used to use the generic propecia from india, however I switched to proscar for my own sanity. I just didn't want to take any chances at all since you go through peaks and valleys when evaluating the performance of finasteride during the 1st year or 2. Every time my hair would look like crap for a while during a shed, I would start to doubt whether or not to the legitimacy of the indian finasteride. Of course, I never had a real reason to doubts, never read anything on forums to give me reason to doubt it. Simply in my head. Proscar is so cheap and lasts for such a long time, I figured it was not a big deal to switch.
