Androcur 10mg (which contains cyproteronacetate) is being discontinued by Bayer because it isn’t economical for them to produce anymore. I hate it. It’s the anti androgen that’s pretty much the standard for feminizing hormone therapy here in Germany and I believe even in Europe.
Edit: here is the email in German that they sent me after I asked them through their contact form: 
Isn’t it not really advised because of side effects?
In France for example it’s really not standard at all, and decapeptyl or bica are used more often.
Nah all my friends r on androcur and it seems to be good
it can cause brain tumors and has some other issues too. others are preferable
