I have been on trt for about 4 months, the first 3 I felt great. I was on 200mg a week, had labs done tt 1450 hct and hcg higher end of normal. I donated blood thinking this would help me out and dropped my test to 100mg a week. The day after I donated blood , I had a panic attack and have had at least 8 more since. I have also noticed increased heart rate and all of my veins look larger. I am currently waiting on another set of labs to come back. I feel physically very good, but the anxiety is driving me crazy. Does anyone else notice the bulging veins, I have a few that look like they are gonna pop on the sides of my head. I have been monitoring blood pressure and it is not high.
