Then get that estrofem ready to use anyways, since adult human bodies are not made to have no sex hormone. If you get depressions or feel bad in general, add E to the mix anyways.
Also: Cypro (Cyproterone Acetate, Androcur is a marketing name for it) requires much higher doses if you do mono-therapy than if you use it to support E: With E the general wisdom is to not exceed 12.5mg/daily and rather increase E-intake if T isn’t properly suppressed, whereas without you may need 50 to 100mg per day, with a massively increased risk of bad side effects.
There is a reason why pretty much no one who has the choice does it that way, but it’s of course up to you!
It’s up to you of course, but don’t expect this to do all that much. I’m on 12.5mg daily and before my last blood-test I took ≈4mg E transdermal and even at that I was still very much on the upper end of the female range for T.
