How old are you ? Where are you located ? It caused me issues but thankfully now all is over . It is very individual but majority of people are fine on it . If you decide to go on Finasteride, it would wise to have your hormones tested to have a baseline (Total T , E2 , DHT , SHBG , Thyroid and Adrenals) . You can catch red flags(if there are any) and God forbid in case you have lasting issues you know what were your levels . In that dreaded case at least you won't fly .
