PRO-LAD

PRO-LAD, also known as 6-propyl-6-nor-lysergic acid diethylamide, is an analogue of LSD. It is described by Alexander Shulgin in the book TiHKAL. PRO-LAD is a hallucinogenic drug similar to LSD, and is around as potent as LSD itself with an active dose reported at between 100 and 200 micrograms.

PRO-LAD has been sold by some research chemical suppliers but might be considered illegal in some countries due to its structural similarity to LSD.
