What is 1P-LSD? A Research Guide to This Psychedelic Analog
With the expansion of Psychedelic research Scientists and chemistry enthusiasts are increasingly turning 1P-LSD to a potent LSD analoguesknown for its unique chemical structure and psychoactive effect. Although there are many things in common with LSD has, possesses 1P-LSD special characteristics that are both for Pharmacological studies as well as for Receptor binding analyses Make it interesting.
In this guide we explain the most important facts about 1P-LSD – Chemical structure, mechanism of action, research relevance, legal status and more.
What is 1P-LSD?
1P-LSD stands for 1-propionyl-lysergic acid diethylamidea psychedelic substance that is structural LSD similar. It belongs to the family of Lysergamides and acts as Prodrug of LSD, that is, it becomes after taking in the body LSD metabolized.
Although 1P-LSD Originally not developed for pharmaceutical applications, it gained popularity in the early 2010s when it Chemical catalogues and Research circles in some jurisdictions as a legal alternative to LSD turned up.
Chemical structure and properties
-
IUPAC name: (6aR,9R)-N,N-diethyl-7-methyl-4-propionyl-6,6a,8,9-tetrahydroindolo[4,3-fg]quinoline-9-carboxamide
-
Summary formula: C23H29N3O2
-
Molecular weight: 379,5 g/mol
-
Appearance: White powder, Blotter paper or solution for research purposes
The only chemical difference between 1P-LSD and LSD is the propionyl group on the nitrogen in position 1 of the indole ring. This modification makes it a Prodrugafter metabolism in LSD is transformed and produces similar psychoactive effects.
Mechanism of action – 5-HT2A receptor agonist
1P-LSD Its effects are mainly Agonism at the 5-HT2A receptorsimilar to LSD. However, it can also interact with other serotonin and dopamine receptors.
Due to its role as Prodrug most pharmacodynamic and pharmacokinetic effects after conversion LSD self-attributed. Using researchers 1P-LSD often for studies such as:
-
Serotonin receptor binding
-
Metabolic pathways of prodrugs
-
Structure-activity relationships (SAR) of lysergamides
Research applications
Although 1P-LSD has no approved medical use, it is researched in the following areas:
-
Neuropharmacology
-
Receptor mapping studies
-
Comparative action analysis with other lysergamides
-
Cognitive and behavioural animal models
Due to its almost identical effects LSD It is a useful AnaloguesWhen access to LSD limited by legal restrictions.
Legal status of 1P-LSD
The legal status of 1P-LSD varies by country and changes frequently. As of 2025:
-
USA: Not regulated at the federal level, but may fall under the Federal Analog Act
-
UK: Class A drug under the Psychoactive Substances Act
-
Germany: Controlled under the NpSG (New Psychoactive Substances Act)
-
Canada and Australia: Often as LSD analogues treated and regulated
Important: Always check local laws before you 1P-LSD Acquire or use it.
Safety and laboratory handling
As with all Research Chemicals Requires dealing with 1P-LSD strict security measures:
-
Storage in a cool, dry, dark place (below 8 °C recommended)
-
Use of gloves, goggles and triggers when handling
-
Precise weighing with milligram scales
-
Contamination prevention and working in controlled environments
Final thoughts
1P-LSD is a fascinating substance at the interface of Psychedelic chemistry and Pharmacology. The close relationship to LSD makes it an attractive Research objectiveEspecially in regions with limited LSD access.
Responsible and legally used, offers 1P-LSD Researchers are a valuable tool for understanding Serotonin agonists, Prodrugs and Lysergamide analogues to deepen.
