Welcome to the site. No one is going to send you the source both because your account is brand new and also as it against the rules. People aren't going to risk it and it isn't personal against you nor to be difficult. I hope you understand. Do some hunting and follow the breadcrumbs like everyone else has and you should be able to find it on your own.
Hope you find everything you are looking for and get peace & serenity.
Hello!
as I wrote I am new and didn't know it is against the rules to give addresses to buy SN
I also understand the mistrust as I have only been on the forum for a short time
and I understand that you don't want to take any risks as the reading of the messages is public
( myself I found by myself this forum (by chance) looking for, I don't remember well, something about suicide methods or buying SN)
I will try to follow your advice and as you wrote 'Do some research and follow the breadcrumbs'
although it is a very difficult on this forum as there is no method of searching by topics or keywords.
If some good and kind soul could send me a PM with some clues or pointers I would be extremely grateful.
An alternative I will try ingesting 30 grams of paracetamol (here in Italy the medicine is called 'tachipirina') hoping that it will work and that I will risk committing suicide.
