Chiraag, taking Red-PCT will lower your estroidal levels. Taking an AI such as Red-PCT blocks the formation of estradiol, so the extra testosterone in your system won't skyrocket your E as well.
Since your testosterone levels are on the high side, lowering the dosage to 150mg sounds like a good move. You might want to consider dropping the zinc, boron and magnesium as well.
It's important to remember that Estrogen is primarily produced by the conversion of testosterone. Our bodies make estrogen by first making testosterone and then using aromatase to convert it to estradiol. So having an excessively high Testosterone count will lead to the production of more Estradiol in your body. By lowering your testosterone dosage, it should have a complimentary effect on lowering your estroidal as well.
Lowering the Test dosage + taking Red-PCT should bring your estroidal levels back to their sweet spot. But make sure to get regular blood tests (2 weeks – 1 month) to make sure that you are on the right path while you are working on fine-tuning your hormone levels.
