Was running test teen mast each at 350 for about 12 weeks everything was fine taking .50 Arimidex twice a week. Strated getting a few pimples on shoulders then one day woke up and entire back was broken out in a hive. Switched instantly over to only test running 500 mg prob should gone to 200. Cant figure out why my I broke out been almost a month now barely any better def going to scar. Cant bench squat etc. Bloody sheets every night. Just got blood work done to see if anything was up. I had raised my Arimidex a week test before thinking maybe I had high e2 but after raising it came back at 25 which is implies it prob wasn't all too high? Only thing I can think maybe I missed a pill and got a severe estrogen rebound effect from the Arimidex. Going to switch over to aromisin regardless
