I just couldn't get hard or able to maintain an erection. It gradually came back after I stopped Propecia and only had slight issues when I was on Generic finasteride which makes me to believe that Propecia was actually working to reduce DHT.
I've tried generic Finasteride for a year and it didn't make a difference and then switched to the official Propecia but experienced bad side effects.
The main side effects were erection problems and shockingly it reduced the size of my penis. I had to stop.
I guess I was one of the unlucky...
I'm considering microneedling every day possibly 2 hours before my night application of minoxidil. I won't do it vigorously and will do that once a week
