for the record before SRS I took 5mg every 2 days and my T was *nuked*, like it was lower than the cis girl reference minimum. I know trans women who took 2.5mg every 2 days and were fully in the cis girl range, but you definitely shouldn't take this thing for life, please go read transfemscience until you learn to fear it.

and stop taking 50mg ,100mg per day my Gods. 50mg at only 20 days/month gives you a 20× increase in meningioma risk. (same goes for medroxy—it's probably not going to kill you but please keep your usage of it time-limited or it *might*)
