5ARIs do all kinds of sh*t. When first starting them or re-starting them I’ve gotten migraines during those first few weeks, increased ear wax and tinnitus, increased sense of smell due to increased estradiol. All kinds of weird sh*t happens when your DHT is out of whack. I still take them by the way, so I am not anti-finasteride. But I also realize that DHT is not useless either. Too many idiots on here are too pro or too anti 5ARIs. For me the effects are tolerable, I won’t deny that they exist, nor will I exaggerate them.
