Sure just sharing facts, like you/I said that's because more frequent dosing of test decreases estradiol.
You brought up SHBG
Sex hormone binding goblin can also bind to estradiol making it inactive, it can also bind to DHT.
Maybe that's why some people here experience "gyno sides" from the consumption of proviron. My knee jerk reaction was the dudes proviron is fake. But after giving it some thought, I thought it would be conducive to bring this up.
Science may not matter to you, but some people find it interesting.
