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: 
10mg were unfortunatly never avaiable in Austria - shame that now production ends Germany as well.
We have 50mg tablets, which isn’t a dose recommended for transfemmes so every 4 doses you have to split them one of them using a tablet slicer. It’s tedious, but it works.
