Hey!
Congratulations!
4 months is a sweet spot. Lots of stuff happen around that time.

Personally I hate Finasteride, and even the medical community is coming around to the idea that it causes more problems than it solves. It's a decent AA but it can also cause depression and alter the state of mind in general. I would suggest you talk to a doctor about alternatives.

Thank you for keeping up posted! Looking forward to more news in the future. Don't forget to take some pictures to document your progress, at least for your own records.
