If you don’t see any sign of progression in 3 months you can quit the medication, you won’t be a responder.
I’ve used really high dosages of HRT, like 150mg bica daily and 4MG estradiol valerate every 4 days, it didn’t change my mind or my behavior, not even my sex drive and sperm production. The problems only came after I quit the med, I presume I had no sexual hormones for a month till my body start producing again, i was producing 0 sperm, I could have an orgasm but with 0 outcome. Also I got gum recession in this time.
