ovral anti-progesterone?

[bubba10]

i heard that the morning after pill is anti-progesterone, is this true? it has some estradiol in it though not much but some. would 25mg of proviron a day be enough to ward off the gyno? and is there a way to take the estrogen out of the pill?

RU486? i've heard that too. i don't know how though.

wintrol is supposedly (i don't know how it does it either) anti-progesterone too.

Yes it is, I have yet to read up on the actual mechanism since the shit is impossible to get I never bothered.

wintrol is supposedly (i don't know how it does it either) anti-progesterone too.

Winstrol has an affinity (ie it binds) to the PR receptor but does not activate it. What this means is that for drugs like fina that also have an affinity to the PR receptor, the winny competes with the fina reducing the amount of PR receptors it can attach to and lowering the effects.
