I've been using a topical for awhile. I tried minoxidil on and off for a few years, including on my face, and it seemed to help some with zero side effects (there are people who claim even that causes rapid aging, feminized facial features, etc) and I'm not trying to get a hair transplant or have a mohawk any time soon. I figured I would try topical fin, actually a solution that has fin and min. Based on a lot of research (mostly idiots on reddit) I decided to try it on a lower less frequent dose and see what would happen.
So, IF there are side effects they are only good ones. I can't say this has anything to do with taking generic topical fin or not but my body composition, energy, erection quality and strength and all similar things are at an all time high. I take it 3-4 times per week and take regular min the other days. One application a day just in the thinning areas, not the 2x daily soaking of the head thing.
