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: 
I’m not doing DIY and I have to get my prescription from my endo. She suggested to switch to spiro. I suggested to her to prescribe 50 mg to quarter them but I don’t have an answer yet.
I personally really don’t like Spiro due to its side effects and lack of good T blocking
Yes that’s why I really want to stay on cypro
