it's accepted among those dirty TERFs that estrogen, when put into a male's body, causes neurological issues, because the neurons in a male's body do not posses the sheathe that female nerves do that protects said nerves from estrogen corroding them.
Maybe you shouldn't trust feminist uber-science too much considering it flies in the face of high oestrogen levels in (non transgender) men - the primary cause of gynecomastia - being considered a very benign condition and men producing oestrogen naturally anyway, with considerable overlaps in the normal ranges for males and females (in fact an adult male has more than a menopausal woman).
There's nothing too concrete, but basically the fact he only ever mentioned taking estrogen once or twice, 2 years ago way back when he first came out, and has since said little or nothing regarding any kind of transition (FFS, SRS, HRT etc). It's possible he is just being private about it, but given AGP's propensity to overshare every part of their 'journey' I doubt that.
He also frequently uses the cop-out of being non-binary, which would actually excuse him not getting any work done to transition, but just adds to the idea this is all a convenient LARP until he finds a new bandwagon.
Didn't he complain about some psychiatric stuff recently ? I interpreted that as him failing to be approved for some kind of transgender stuff, personally, which would possibly (and very understandably, given he pretty much self-admits to being a basket case) prevent him from getting all that.
Should be noted that since he just moved to the U.K., he may have fallen into legal waiting time for that kind of things, especially if whatever stuff he did in the U.S. wasn't done very "officially", with a recognized psychiatrist and stuff; He may have had to start back from level 1 with surgeries needing a year or two of actual follow-up - in France it works that way.
So, yeah, I think it's quite possible he doesn't share because all he has to share is taking fat Ls from the psychiatric system, and while people fixate on him talking about muh trans' genocide, I think that despite that he is very much not the kind of person to share his
personal defeats at the hand of evil TERF-Island.
There's a difference between a system trying to oppress you and succeeding because you're too fat and unhinged not to get caught by the safeguards loads of people manage to get through every year. I think he's fine, even ecstatic at the former's prospect because of the narrative it weaves, but admitting to actual, factual Ls ? I don't think he does that.
