I have been on TRT for 3 month's at 1CC a week. recently I have noticed I am grumpy and a bit short with people on day 2 - 3 after injection, and then its smooth sailing the rest of the week leading up to my next injection. I assume this is due to aromataze & E2? I am using erase at 2 caps the day of, as well as days 2-3 post injection. I have realy noticed the mood change this week in particular. Any thoughts on what might be going on here? I am going back to my Doc tomorrow to discuss this, but would appreciate any input prior to seeing the Doc. Should I request Arimadex? what is everyone elses protocol on controling E2?
