it could slow it down for sure or you'd maybe lose strength, but since you're starting from such a high point and you presumably intend to keep working out, i wouldn't say it'll kill it. my personal trainer is jacked as shit and she's a woman. you may find certain activities or recovery easier, even, although that's a lot more speculative
look at it this way: would you rather be stronger as a guy but miserable bc you’re not on estrogen, or be a little less stronger but feel a lot better bc you’re on the right hormone? (and again, you can still be a buff woman. estrogen doesn’t turn you into someone permanently built like a twig)
Sorry I’m rambling a bit but one last note I promise 😭 Yes it will be a bit harder to progress in gaining muscle BUT the benefit is that estrogen makes it so it takes longer to loose that muscle you built up. Your metabolism is much slower on E, and while there are disadvantages to that, the advantage is that it’s much easier to maintain stuff long term. So if you skip a few days of gym because you’re sick or something, you are proportionally going to loose less then you would off of E
