Yep it is dangerous but so are lots of other things. That's not to say people should just start popping pills but most doctors at least in the UK aren't all that clued up either unless they specialise in endocrinology.
My endocrinologist actually documented that I was very informed about self medicating and the risks involved and whilst I am now on prescribed hrt having a good knowledge about the risks and consequences wasnt a bad thing. My mental and physical health generally has actually significantly improved since I started hrt. I gave up alcohol, lost a lot of weight and quit smoking.
So yes it's definitely not for everyone but at the same time for some it's the only choice given poor access to healthcare or long wait times involved to access it. Self medicating for me has made it easier to get on prescribed hrt and get blood tests and my health monitored as a consequence.
I would never encourage anyone to try it or start but feel that sharing of knowledge and reliable sources is no bad thing to minimise harms in those who might make bad decisions or purchase from shady sources otherwise and might just go out and purchase on a whim.
Herbals are definitely not safer given lack of regulation about them and what goes into them. Plus they are likely to lead to excessive dosing given the lack of apparent effects.
So whilst I don't disagree that prescription meds are dangerous if are in the wrong hands but it isn't difficult to educate yourself about the possible effects both wanted and unwanted and ensure that any dangers to health are minimised.
