I've struggled with estrogen management since I began trt about a year ago. I've always injected Sub-Q and the research supports T levels through Sub-Q. However, at my Wit's end I decided to begin injecting in my deltoid about 2 weeks ago. It's really made a big difference in my estrogen side effects. I haven't used an AI I'm over a week and though I can tell my estrogen up a little bit, normally my side effects are off the chart by now. I'm going for blood work later this afternoon just so I have a legitimate understanding of what my estradiol number actually is compared to my current state. However I definitely feel better now than I have in a long long time. I I'm hoping this continues obviously
