2 months is a short time to get a feel of what's to come.
When I was a few weeks into Finasteride, I experienced ballache, and seemingly lower libido. To this day, Im still unsure whether my libido has been affected for sure, but the ballache subsided a couple of weeks later. No other significant side effects.
As for the benefits, I saw the peach fuzz turning dark and thicker around 6 months mark, and I would say the crown also showed improvement. The hairline did not change much, but was enhanced by the few darkend hairs enough to see a minor cosmetic difference. However, Im sure I have maxed out the benefits now, as these hair are staying the same length while the adjacent terminal hair keep growing longer. It's now a matter of maintaining and keeping an eye on any further recession...I have no idea what to do when that happens.
No need to envy a 45 y.o guy with a NW3v balding head and looking to transplant with possibly less-than-stunning results lol. You're in a position to fight DHT.
Your age is on your side, and it's up to you to decide when to tackle DHT...and I'd still say sooner rather than later.
