The people doing bleach and ivermectin were not doing their own research. They were screeching "do your own research" while denying the actual research and reading confirmation bias entertainment.

Bioidentical hormones are safe, the big risks come from the older derivatives like premarin (synthetics with high blood clot risk) or taking hrt levels of birth control type estrogen- there's some parts of the world that's what they still prescribe. Another big avenue of risk is infection/contamination with injectibles, due to this a lot of DIY people are making transdermal gel.

Anti androgens are expensive, estrogen is cheap. Anti androgens have high risks and dangerous side effects. Bioidentical estrogen has none. Doctors love to microdose the E and macro dose the AA. But mono therapy estrogen levels are enough to suppress testosterone without AA.

I've read the research from a trans girl who simulated pregnancy hormones and took her body through it.

Everything is risk assessment and reduction; cis people and trans people have different priorities on what those risks and reductions are. Such as the medical community wanting to give us the bare minimum, in dose, in care, in practice, in understanding.
