Anyone else seen a jump in resting heart rate ? Mine has gone from around 75 to 90bpm. It’s a little scary sometimes. I recently gave blood because my hematocrit was elevated but it really didn’t change my heart rate. I’m on 20mg day of test which puts me in the mid 500’s and I recently added a small dose of ai because my e2 was up at 55. Any ideas what could be causing this heart rate ?
