Most people don't realize this, but you can order a synthesis of just about any (legal) chemical with enough money. People do it for pharmaceutical or nootropic drugs sometimes in group buys. It's trivial if you have enough money to find some vaguely legal analog of a recreational drug, and order a synthesis of it. 2f-dck is a ketamine analog that I believe is still legal and reported to be very similar in effect, and I'd guess 2f-nendck is somewhat similar to that. Not that I'm suggesting anyone should, there are risks and it's not an easy process. It's just interesting how easily accessible it is if you have the right information.
Even more stupid, I get phone calls and email asking me if I can source stupidly well known illegal drug for a friend doing some research. Even if this is clear that I am just providing experimental data and no chemicals at all.
So yes, you can get chemicals very easily and you have a lot of providers which are not really looking at the legality of the stuff.

The first 5 minute of this is one of the funniest things I've watched.
Weird. Mormons getting salty?
Most of them are well worth a watch, get them if you can.
I did not see anything overtly Mormon, however. The LDS copyright block is confusing.
Worked for me in the US
The same is true for the aforementioned YouTube link (which is accessible from the UK and Ireland according to https://polsy.org.uk/stuff/ytrestrict.cgi ).
When you sell stuff as medicine, food or anything in between, of course it should be on you to prove that it's safe. That's not unreasonable.
Neither is it unreasonable to ask, if you sit there with 100kg of some novel molecule custom ordered from a Chinese lab, what you were planning to use it for. And it'd better not be selling it for consumption.
That may have been the case before covid, now you just need enough money to buy the regulators.
PS the Chinese abbreviation for "CanKet", 2F-NENDCK, most likely stands for N-ethyl-nordeschloroketamine. It is almost certain this drug was synthesized by a Chinese custom synthesis group (the most typical source for these type of substances at scale) and not by Australian clandestine chemists.
