I hate to say but this whole thing sounds like some pretty bad voodoo to me. Whatever this compound is, the vendor is not really making much of an effort to help people figure it out.
Changing its name to "LSBD" - which means absolutely nothing chemically, likely after reading this thread and finding out people are suspicious of whatever they're selling, was a dubious move. I feel like the chemical 'researchers' who ingest untested hallucinogens for the sake of spreading knowledge about whether their effects are safe and desirable at least deserve the privilege of knowing what exactly it is they're putting in their bodies. I mean what are they trying to file a patent on this thing?
This LSB 'derivative' could be absolutely anything - seeing as it's hallucinogenic and fits on a blotter, it's likely an NBOME as I and many others have suspected. NBOMEs are available at pennies a dose and if re-sold as a lysergamide for dollars a dose could fetch a fairly hefty sum if people are foolish enough to believe it. There's the off chance that the vendor or whatever chemist(s) he/she obtains their products from have developed some new and desirable psychedelic active at microgram levels and altogether unrelated to the ones which already exist, but I for one find it pretty hard to believe.
I wouldn't ingest this compound. Not unless the vendor shows some sign of knowing what the hell they're talking about. If they were smart they would have left it as is at LSB, people were starting to believe it. The whole LSBD thing just makes it sound like they're running away from something. Unless maybe it really is n-acetyl LSB or something... but if everyone gets an email now saying it's that, I'll be real suspicious
At this point I think this thread may simply be inadvertently spreading misinformation about the effects of the real compound in question:
Lysergic acid sec-butylamide, and will perhaps give some unlucky fellow who stumbles upon the actual compound some false assurance as to its safety
