Hi all , first off, excuse me for any newb questions but I need some insight . Started my first test cycle, test cyp 500mg/week for 10 weeks(test only). Today was my 2nd shot and I’m noticing my libido is dropping and hard for me to get an erection. When I cum, the load is very small compared to before. I’m guessing this has something to do with my estrogen levels rising . I have Arimidex on hand but haven’t used it yet because I have no signs of Gyno or water retention. Thoughts ?????
