As a transwoman who has been on hormones for 7 months and lost all of her strength and gets her ass handed to her in all things physical, it's going to depend heavily on the individual, their genetics, liver metabolism, neurological sensitivity, the impact of first puberty and if it wasn't blocked, when they first started hormones, which makes this a big gray area. Testosterone levels alone aren't a good measure. What about your sensitivity to Testosterone? Or how long testosterone induced changes remain? Even a rule "you have to be on HRT for this long and have bottom surgery so you no longer can produce it" isn't a good indicator because people transition wildly and their bodies handle hormone replacement differently. Some will feminize several factors faster than other women. Some don't see changes for years, others are steamrolled by overwhelming physical and mental changes that make it hard to function normally while they adapt. (Such as in my case)

ALSO it's not just about testosterone and muscle. It's about how much feminizing by Estrogen has taken place (not levels, which have don't represent actual change that's taken place) which timeline is wildly different between trans women. There are huge differences there. And some changes can't be reversed or take decades. Which pelvis bone do you think has the advantage? She went from pushing her male body to its limits which it learned to maintain and then switched over to being female while still training her body and not losing the muscle and regaining it. In this case... it seems unfair. EDIT: After watching the video of her competition, yeah, holy fuck, that's not fair at all. She transitioned at 30 after training as male for years, is still walking with her upper body (center of gravity / pelvis rotation hasn't completely changed), her ribcage and shoulders are wide and huge, and when the weight is above her head she has essentially a male stance and frame and lung capacity. 2 years with that body mass after all that training at that age isn't going to be enough. I'm glad she's discovered her true self but... this is not fair to anyone in this competition. Here's a picture of her and her team-mates.

When it comes to competition, muscle density and bone density should be looked at carefully, along with other estrogen feminization traits (such as pelvis rotation, center of gravity, blood flow, vein size, fat distribution) along with requiring bottom surgery. (So they can no longer produce testosterone for easy doping) It's a messy, messy gray area and depends on the individual. If they have any kind of advantage from their time having a male body, then no they shouldn't compete. Otherwise, hormones and genetics can get you within competition range with cis-women in your height and weight range. Or in my case, worse than cis-women. Last month I was found crying trapped between my mattress and the wall.

It's a huge gray area, more evaluations are needed, as honestly testosterone levels aren't likely enough. Personally, despite being liberal and transgender, I don't feel pride watching these videos (this doesn't seem... like the point of taking hormones or the supposed wanted effects of estrogen - I lost all desire to compete and loved losing all my muscle and gaining a girly frame... but I know everyone is different and I'm SUPER feminine. There are definitely trans tom girls) and worry about backlash to the trans community when the public sees it, especially if they see strong male features and they are aggressively dominating the competition. Any kind of ignorance makes this look terrible, and people just like the meme above describes even though it's more complicated. It's great they are following their dreams, but there is actual science to contend with, and more research and testing needed to determine at what point do trans women no longer have an advantage. In my case, seven months is all it took to find me crying under the sink trying to get a pickle jar lid off.

In the meantime, it's going to be a big gray messy area everyone is going to fight over.
