SERM’s increase estrogen levels. You need SERM+AI.
I have no expectation that one SERM might be better than another.
You have gyno that is not from a SERM deficiency. Your E2 or E2+prolactin is the cause. Do you have labs?
If prolactin is elevated, you need a MRI screening to see if a prolactin secreting pituitary adinoma is there. If so, that can be managed with 0.5mg/week cabergoline/Dostinex.
A SERM cannot block the effects of prolactin!
Your SERM cocktail is an overdose. I would expect high LH levels leading to high amounts of T–>E2 aromatization in the testes. And anastrozole cannot reduce that. For SERM+AI to work, you need to be using sane doses of SERM and there is no reason to stack two SERM’s. More can be worse, but a testament to your enthusiasm and wishful thinking. Don’t pay attention to the BB broscience where guys post about doing such things, they are misinformed and ultimately reckless. Many guys on SERM’s do better on half dose or EOD dosing.
E2 levels can be high if the liver is not able to clear E2 from your blood stream. Some OTC and Rx drugs can do that. AST/ALT lab work can detect some of things like that.
