1D-LSD (1-(1,2-dimethylcyclobutane-1-carbonyl)-lysergic acid diethylamide hemi-L-tartrate) is a psychedelic research chemical and lysergamide derivative with an ergoline backbone.
1D-LSD is a prodrug of LSD and an analogue of 1V-LSD. Since it is a prodrug, it shares many similar properties with LSD itself but also 1V-LSD, 1P-LSD, 1cP-LSD and 1B-LSD.
1D-LSD has a standard long duration like many lysergamides, with an onset of about 30 minutes. A long, drawn-out peak can last anywhere from 6-8 hours, with the comedown bringing the
total duration to about 10-13 hours.
AN ANONYMOUS RESEARCH REPORT ABOUT 1D-LSD:
" ... 1D-LSD is another fine addition to the growing ledger of 1-substituted LSD analogues. This is by far the most potent 1-substituted LSD analogue I have tried. To answer the
biggest questions- yes it will yield an experience similar to LSD, and the tabs dosed at 150 µg offer a substantial experience that is not to be taken lightly- in fact for the
inexperienced I would recommend not even consuming an entire tab. It bore all the hallmarks of a lysergamide- patterned intentional visuals, teal-pink color schemes, a long duration
with a drawn out euphoric stimulating afterglow, analytical, sentimental, profound and joyous headspace. This is certainly a compound that offers a worthwhile experience. ...
