First Time with LSM-775 I got some of this in the mail a few days ago and made blotter dosed around 1.1-1.2 mg. Today I had the chance to try it and took 1 hit. I was alone throughout the trip. I have experience with various psychedelics. I've tried LSD, 1p-LSD, AL-LAD, ETH-LAD, LSZ, HBWR, and other psychedelics.

Summary
Lysergic acid morpholide (also known as N-Morpholinyllysergamide, and LSM-775) is a novel synthetic research psychedelic of the lysergamide chemical class that produces a generally similar albeit significantly less psychoactive array of LSD-like psychedelic effects when administered. It is a close structural homolog of LSD known mainly for its obscurity, low relative potency, and a few comments that have been made on the "dream-like" sedation it produces as well as potential nausea and other potentially uncomfortable physical effects.

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
