Buy LSZ L-Tartrate Pure is a high-purity research chemical powder of the lysergamide class. Laboratories and researchers use it to study serotonin 5-HT₂A receptor activation, psychedelic pharmacology, and structure-activity relationships of LSD analogs.
What is LSZ?
LSZ (Lysergic acid 2,4-dimethylazetidide), also known as Lambda, is a synthetic lysergamide and a structural analog of LSD. It features a 2,4-dimethylazetidide group instead of the diethylamide found in LSD. First synthesized by David Nichols, LSZ is known for producing psychedelic effects that are very similar to LSD but often described as slightly more clear-headed and visually distinct. Sold strictly for laboratory and research purposes only.
