Yes apparently progesterone-induced gyno is attributed to elevated oestrogen levels. Caber will do nothing for progesterone, only combat the elevation of prolactin by increasing the production of Dopamine.
Prolactin-induced gyno is apparently related to suppression of testosterone, by way of secondary hypogonadism.
The Caber will most likely make you feel like a piece of shit after you take it, but maybe your dose is low enough to not have these sides. I along with BBB could not handle caber or bromo well.
Another thing I was curious about is, with elevated dopamine levels and lower prolactin levels, shouldnt one's refractory period decrease greatly? In theory it should...
