1D-LSD
1D-LSD is a prodrug of LSD with a 1,2-dimethylcyclobutane-1-carbonyl group at the N1 position. User reports suggest it is approximately 15-25% less potent by weight than LSD-25, though this varies between individuals and batches. Some blotters sold as 1D-LSD have been found to contain 1T-LSD (1-thienoyl-LSD) instead; reagent tests confirm lysergamide presence but cannot distinguish between analogues. Users report a slightly faster onset (20-30 minutes) and somewhat shorter duration compared to LSD-25. Volumetric dosing is recommended for microdosing.
