Takes me a long time also..... People these days ABUSE ANTI-ESTROGENS.
I was stupid too as a newbie...used too much of them...and fucked up my lipid and cholesterol profile...
Now i dont take any anti-aromatose at even 1+g of test a week. Not needed for me.
Also....if you are on too much juice.....you will have a hard time( no pun intended) getting off i have noticed. Whereas when i reduce my dose to say 400 Mg/week of test and nothing else..... I can get off and rock hard in a heartbeat. It has to do with Prolactin, Estrogen, Test, SGBH, Free test, and other blood levels.
If some are thrown off eighter high or low...you may notice it in your performance...either in a positive negative way.
Just because you are taking more of something doesent mean its going to help your sexual performance...it ussualy decreases it after a certain level in dosage is reached.
