it's more accurate to characterize LSD as semi-synthetic, just like thebaine derivatives such as hydrocodone, hydromorphone, and oxycodone. it's a simple one or two step transformation from ergot-derived alkaloids.

it seems like MM120 is literally just the "optimal dose" of the tartate salt (the normal salt LSD is co-crystallized with) of LSD in a pill. it doesn't seem like there's any special delivery device, nor is it any sort of prodrug nor is it a deuterated analogue.
