You still have your larger bone structure. Larger musculature structure and different muscle insertions. different ligament structure. different skin structure. different grip strength. Broader shoulders, narrower pelvis, different angled limbs. all of that isn't going away even if it atrophies. And you aren't going to let it atrophy because you are an athlete in training managing your dietary macros. Maybe recovery isn't as efficient lacking so much excess testosterone but you still have some.

Is there actually an advantage? that's toted. but no one can ever point to real data about it... and all the data suggests the exact opposite... that for most cases: cis-women out-compete trans-women.
