1V-LSD has been around since July 2021. There’s anecdotes that it is remarkably similar to LSD and it, like other novel lysergamides, is a prodrug for LSD. It is the fifth iteration of a Research Chemical that converts to LSD in vivo, and is a legal NPS. It was created/discovered as a legal alternative to 1cp-LSD (a legal alternative to 1P-LSD at the time) which was banned in Germany in July 2021. I think the timeline is 1A-LSD>1P-LSD>1cP-LSD>1V-LSD. B & Z carry a lousy rep.
