you do realize that using cyproterone/spironolactone in combination with an NSAA basically renders them (bica/flut) useless right?
"All medically used SAAs are weak partial agonists of the AR rather than silent antagonists, and for this reason,
possess inherent androgenicity in addition to their predominantly antiandrogenic actions.
[75][76][77] In accordance, although CPA produces feminization of and ambiguous genitalia in male fetuses when administered to pregnant animals,
[90] it has been found to produce masculinization of the genitalia of female fetuses of pregnant animals.
[76] Additionally, all SAAs,
including CPA and spironolactone, have been found to stimulate and significantly accelerate the growth of androgen-sensitive tumors in the absence of androgens, whereas NSAAs like flutamide have no effect and can in fact antagonize the stimulation caused by SAAs.
[76][77][91] Accordingly, unlike NSAAs, the addition of CPA to castration has never been found in any controlled study to prolong survival in prostate cancer to a greater extent than castration alone.
[76] In fact, a meta-analysis found that the addition of CPA to castration actually
reduces the long-term effectiveness of ADT and causes an increase in mortality (mainly due to cardiovascular complications induced by CPA).
[92] Also, there are two case reports of spironolactone actually accelerating progression of metastatic prostate cancer in castrated men treated with it for heart failure, and for this reason, spironolactone has been regarded as contraindicated in patients with prostate cancer.
[93][94] Because of their intrinsic capacity to activate the AR, SAAs are incapable of maximally depriving the body of androgen signaling, and will always maintain at least some degree of AR activation.
[77][91]"
hope this helped
