1Fe-LSD, also known as 1-(ferrocenecarbonyl)-LSD or as SYN-L-234, is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD). [1] [2] [3] It is thought to be a prodrug of LSD. [1] [2] [3] The drug was patented by Lizard Labs in 2024. [3] Subsequently, it was encountered online as a novel designer drug being sold in Germany in November 2025. [1] [2] 1Fe-LSD as the hemi-L-tartrate salt has been sold in the form of blotter containing 200 μg per tab and micropills containing 300 μg per pill. [1] [2] 1Fe-LSD contains ferrocene, an iron compound, which is an orange organometallic compound and is assumed to result in the distinctive orange color of 1Fe-LSD blotter and pills. [1] [2]
