As far as i know winstrol does bind to the progesterone receptor. Winstrol does not fully put a hault to the progesterone. It partially blocks it. It is not progestenic itself but does work to even symtems out when taking drugs like deca or anadrol that may have progestrogenic properties in themselves.
RU486 (aka the abortion pill) binds to the uterine wall in females &
amp; blocks progesterone. Not sure how or where its effectiveness takes place in males but I have'nt seen enough evidece on whether the cost benefit ratio is worth it. It does elevate cortisol drastically &
amp; can cause other problems as well.
