An analog of LSD is ETH-LAD CAS # 65527-62-0 or 6-ethyl-6-nor-lysergic acid diethylamide. In the book TiHKAL, Alexander Shulgin explains it. ETH-LAD is an LSD-like psychedelic drug and is slightly more potent than LSD itself, with an active dose of between 40 and 150 micrograms recorded. ETH-LAD, described as less demanding, has subtly distinct effects from LSD. This product is sold in the form of pure powder, not on any blotter paper or pellets.
