"To avoid progesterone sides,you have to get some Myfegine or some Cytotec..."
Italianboy, could you please post some links to abstracts that say Cytotec works by blocking Progesterone.
I did a fairly comprehensive search on the net, and what I found is that Cytotec is a labor inducing prostaglandin taken intravaginally. It can be used to speed up the labor process, and it can also be used early in pregnancy in conjuction with RU-486 for abortion purposes. This is the only connection I found between the two drugs.... they do not share the same mechanism of action (RU-486 blocks progesterone and prevents uterine binding or something, while Cytotec induces contractions to flush everything out).
Even if Cytotec had some anti-progestenic effect, it would not be an effective drug. It reaches peak blood concentrations 20 min after administration, and has a half-life of 40 min.
I just don't understand your reasoning that points to this compound preventing progesterone sides.
