This thread is entirely from my research on this subject and should not be taken as fact untill your own research has been done for personal confirmation.
OK, Prolactin and progesterone do not have direct effects on each other.
Estrogen and Progesterone do. Prolactin and testosterone have direct effects on each other.
Elevated estrogen levels means a decrease in progesterone levels and vice versa.
Elevated Prolactin levels means lowered testosterone/dopamine levels and vice versa
SO
Explaination:
When prolactin levels are increased, testosterone and dopamine levels are reduced. With that testosterone decrease, your body reduces the amount of estrogen being produced as well which results in an increase of progesterone(this is why most catagorize progest./prolactin together)
Now if a prolactin inhibitor is introduced such as Bromo, your test/dopamine levels will raise. This raise in testosterone can trigger your body to produce estrogen to compensate this increase. At this point progesterone is decreased to balance out the estrogen/progesterone ratio.
So in the case of a Fina cycle. Fina is administered, and prolactin increases(common with Fina). With that prolactin increase, the persons testosterone is lowered(along with dopamine). The lowered testosterone triggers a decrease in estrogen production which raises progesterone.
This is the reason why it is very important to have an anti-estrogen and prolactin inhibitor when partaking in a cycle that increases prolactin such as Fina or Decca. If you lower that prolactin with Bromo, your test levels will increase there by increasing estrogen production.
If a Prolactin inhibitor is not available, Vit. B6 can reduce prolactin in some. I have had success with 800mg split through the day.
Prolactin inhibitors possibly available:
Bromocriptine
Pergolide(Permax)
Cabergoline
Quinagolide
Terguride
Any of these should be researched before administration and I am not suggesting these. Just listing
Anti-estrogens should not need listing.
