"RCs" is not a single drug, but a massive different number of unique drugs. They're all different. 4-HO-MPT or 4-AcO-DMT or any other RC psychedelic is absolutely nothing whatsoever like kratom, kratom is a mild opioid high, whereas the others you listed are more like mushrooms or DMT or something like that (but different, too).
Anyway yeah, what others said, 5-MeO-DMT can't be eaten, you have to smoke it, or snorting it works too. You will get INCREDIBLY high, unless you got bunk stuff. And be very careful, the dose is like 5mg, a very tiny amount.
