Hi Bailey, That is an extremely high estradiol level, considering it's best to keep your E1/E2 total under 100. You don't even know your Estrone level and it could be just as high. I will say, I have a hard time believing it's really that high if you are only injecting 150mg T per week. Did you have it checked more than once? Measuring steroid hormones is a complicated laboratory process with multiple steps and places for errors to occur. It seems reasonable to think your estrogen is higher than it should be, and that can ruin the potential benefits of your TRT even if you were taking an optimal dose. Estrogen conversion is the most important thing to manage, the main reason it would be useful to be managed by a doctor. But I have hardly ever seen other practitioners order both Estrone and Estradiol levels and control them in a logical manner. It's usually some one size fits some people protocol that isn't right for many men. I'll attach my TRT handout here for you, and you can let us know if you have any more questions after that. I would get new labs with both Estrone and Estradiol, and check a Total Estrogens level too just to help calibrate things so they make sense. In my opinion, you should be using a lot more testosterone too, but figure out the estrogen thing before increasing your dose.
