Dear Jinette and Vincent, I would really appreciate your advice, please put me in the right direction. I have been on treatment with 250 mg Sustanon once weekly. After the results below, I was advised to increase the interval to every 14 days and start taking half a tablet of Arimidex once a week. I feel really good on the once-a-week protocol, but I am struggling to control my estrogen. I am concerned that 14 days may be too long of a break for me. Any guidance would be greatly appreciated. Sensitive Estradiol (E2): 69.2 pg/mL Total Testosterone: 9.97 ng/mL Free Testosterone: 307 pg/mL Hemoglobin: 15.4 Hematocrit: 46.4 Estradiol / Estrogen: 69.2 pg/mL thank you!!!
