The one that numbed your mouth was an NBOME, the other may have been a huge variety of stuff.

This is the most accurate answer, while it does very much sound like 25I-NBOMe from your description, there are a few RCs which have 'similar' effects to LSD that are bitter.

But it most likely was 25I-NBOMe considering the potential profit of reselling it as LSD.

If you have any left, consider picking up a test to see what it is.

You will probably have better luck asking in r/Drugs, r/ResearchChemicals, or a related sub.

I've removed it from here as the question is unrelated to the dark net.
