I started my first cycle about 2 1/2 weeks ago. I'm injecting 250mg sustanon twice per week. I'm using arimidex for my AI, started out at .25mg EOD. After the first week I noticed that my nipples were a little bigger and more sensitive. A week ago I increased the arimidex to .5mg EOD. My nipples are maybe a little less sensitive although the size is the same. Will they eventually shrink back to normal? Anything else I should do? Thanks for any help!
