Just to add a few things, this seller has recently been mentioned in the British press:
Websites, found through a simple internet search, connect vulnerable people with thousands of forum members who provide instructions on how to end their lives.

His meto and SN are legit. His meto is shipped in original medicine packages (yes, I have ordered from him months ago), I haven't tested his SN but it
looks legit, certainly considering many users on this forum ordered from him. Only a few weeks ago he added MDMA and N to his store, to my surprise. He also added propranolol recently, so he's clearly trying to reach the "suicide market".
If I understand correctly, one user asked him to add N to his store and a few days later he did so. It's really suspicious, how does he suddenly has access to this drug? Still, I wonder why he would suddenly start to scam people, considering his good reputation. An exit trick, like you explained? Maybe. Just selling these products on the clear web is indeed the best way to gain attention from law enforcement. Also, he's not giving any useful information to me via e-mail as well.
I personally wouldn't order unless there are reliable reports (EC lab reports) of his N being legit.
