Buy 1B-LSD 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 1B-LSD?
1B-LSD (1-Butanoyl-lysergic acid diethylamide) is a synthetic lysergamide and a prodrug of LSD. It features a butanoyl group attached to the indole nitrogen of the lysergic acid backbone. Like other 1-acyl LSD derivatives (such as 1P-LSD or 1V-LSD), it is believed to convert to active LSD in the body. It first appeared on the research chemical market around 2020 as a legal alternative in certain jurisdictions. Sold strictly for laboratory and research purposes only.

Effects (Research Observations)
1B-LSD acts as a potent 5-HT₂A receptor agonist after metabolic conversion to LSD. Reported research observations include:
- Classic psychedelic effects: rich visual distortions, geometry, color enhancement, and fractals
- Deep introspection, philosophical thinking, and emotional insight
- Euphoria, mood elevation, and altered time perception
- Onset: 45–90 minutes (oral)
- Duration: 8–12 hours
Important Note: These are not approved medical effects. Risks include anxiety, psychological distress, increased heart rate, and challenging experiences (“bad trips”). Strictly for research use only — not for human consumption.
