You can access the peaceful pill handbook, dec 2019, here :

NOTE : I suggest avoiding the wiki link given above by @Death.
It contains documents that may be "read/write" instead of "read only".
Such documents should be considered unsafe.
Scammers may edit documents, changing a seller's info to their own contact details.
Malicious people could edit email / web addresses, phone numbers, dosages, or any info in the document.
The link I've given above contains "read only" documents, because "anonfile" (the hosting site) doesn't allow editing / re-uploading to the same URL.
The thread explains the various document security issues.
In general, you should cross-check any/all info from documents with someone having an up-to-date and trusted version, or by some other means of verifying.
