Couple of questions

[2020]

1.What's your suggestion on how to keep track on sides? In that small chance if I get any, should I continue or give up imidiately? (THO I PRAY I'M HAPPY MAJORITY)

I would continue using it 2-3 months no matter what. Your body should adjust over time to lower levels of DHT and sides should go away.

2.Approximately for how long can I expect finateride to give satisfying results? Is it true that some people even after 15 years of using it keept good results? (ALSO PRAYS I WILL GET MAXIMUM OF IT)

the official study shows that, on average, the subjects were able to maintain/improve their hair for 5 years.
Another study came out saying that for something like half the people it will work 10 years.
15 year is kind of rare actually.

3.It's not about your body to get used to finasteride, it's about that level of DHT is getting higher and higher as you age, right?

DHT levels go down as you age actually....

4.What do you do when finasteride is not that much effective? You make higher dose? And later get on Avodart or what's it called?

avodart, or you just hope that something better comes along within the next 5 year which it will in this case.

5.Treatment shed... could it be cosmetically too much obvious? I want to be prepared and not freak out...

could be, but it's not very common
