Yeah, I looked it up to see if they were more in the strength range of a male or a female because I saw a trans man in the Winter Olympics, and whatever I read said they were on the lower end of the male strength bell curve. I can't remember the website, but I got there through Google.
It described males as, on average, something like 1.9-2.5x stronger in the upper body than females, and trans men as 1.6-2x stronger because of testosterone's effects on muscle and, I assume, bone density. So they would be more like a weak man than a strong woman. However, heart size, lung size, height, and hand and foot size would still fall within the female range, so they couldn't compete with men in sports, but it would be hard for a woman to fight them off if a transman attacked her.
A really sad fact from when I watched a YT vid of a girl who was on testosterone said that it made her vocal cords thicker, but her obviously her neck size was still in the female range so she lost her ability to scream.
Its all a bit fucked up to be honest.
