Estradiol Enanthate Injections and Cyproterone?

Hi! In a few days I'm switching to DIY hrt because my endocrinologist won't raise my dose as much as I want to. He raised it to only 0.050mg/24h estradiol patches in my first hrt follow up appointment because he insists on going slowly.

My blood tests after three months of two 0.025mg/24h estradiol patches a week and 12.5mg of cyproterone daily were: 14.3pg/ml estradiol and 66ng/dl testosterone. I'm ok with my T levels but not my estradiol levels.

My question is: Even tho I know that usually with injections monotherapy is enough to suppress your T I wanted to know if I could still take 12.5mg daily of cyproterone just to make sure my T stays low and if it's safe to do so.

Getting more cyproterone won't be an issue because here in Spain thanks to the public healthcare is cheap to get.
