Actually, the resources section doesn't currently have a good/up-to-date link as far as I know.
The Dec 2019 peaceful pill handbook can be found here :
https://sanctioned-suicide.net/threads/pph-dec-2019.30370/
There is also a Mar 2020 version here :
https://sanctioned-suicide.net/threads/peaceful-pill-ehandbook-2020.35699/
However, I had some issues accessing it, so maybe see how you get on.
Also, I don't know if it's searchable....
The Dec 2019 version above can be text-searched....
