What is Ald-52?
1.
ALD-52 or N-acetyl-LSD, is a chemical analogue of LSD (Lysergic Acid Diethylamide). It was originally discovered by Albert Hofmann but was not widely studied until the rise in popularity of psychedelics in the 1960s.
Effects
In TiHKAL, Shulgin touches briefly on ALD-52 in entry 26, LSD. His writings are vague, second hand accounts, saying doses in the 50-175µg range have resulted in various conclusions. One found that there was less visual distortion than with LSD and it seems to produce less anxiety and was somewhat less potent than LSD. Another report claimed it was more effective in increasing blood pressure. Yet another could not tell them apart.
It has the same characteristics as LSD, but supposedly "without the anxiety, tenseness, and other problems inherent to it".
"your tripping, did you take that lsd. No its Ald-52"
