Allylestrenol has a powerful Progestational effect, reducing myometrial activity
and relaxing uterine hypertonic state.
Some have suggested that it has Progestational activity, similar to nandrolone, and is not actually estrogenic at all.
Methyltrienolone does not convert to estrogen, but it does have Progestational activity which may increase the effects of estrogen.
Clomiphene citrate has no apparent Progestational, androgenic,
or antiandrogenic effects and does not appear to interfere with pituitary-adrenal or pituitary-thyroid function.
It reported no significant Progestational effect inherent in oxymetholone or methandrostenolone, slight
activity with testosterone and strong Progestational effect inherent in nandrolone and norethandrolone.
This gives Nandrolone a small, but measurable Progestational activity in the body,
which provides it with an attraction to the Progesterone receptors located in a number of tissues throughout the body.
