Swim has experienced it all, in all methods and ways to do it. Except PCP and METH.
I have a difficult time with people that have "done it all" or "seen it all".
It's just infinitely unlikely to be true. If you had checklisted even just a quarter of all the known psychoactive compounds at reasonable dosages, I would imagine that the series of ego and mind shattering humbling experiences would have taught you AT THE VERY LEAST that you know very little in this existence about yourself and the universe.
Reminds me, I was once at a restaurant with my girlfriend in BC and I asked the waitress what kind of salad dressings they had. She replied that they had "all of them except blue cheese". So I asked for Japanese citrus-ginger, which she did not have. And then Black Truffle... she stared at me. It turns out that she had "All of the "Kraft" series, except blue cheese" wow.... that's quite a difference. When did Kraft become "all" ?
So you've probably "tried it all" in your little area of the globe, but that represents little. Have you tried BZ? or ALEPH-7? Sinicuichi? Amanitas? Mandrake?... I think you should add more to your list.
No offense, but what you haven't tried and what you don't know could fill a soccer field and then some.

Shakespeare's Hamlet. But you've probably read it already.
Cheers.
