(6aR,9R)-N,N-diethyl-7-methyl-4-propanoyl-6,6a,8,9-tetrahydroindolo[4,3-fg]quinoline-9-carboxamide
1-Propionyl-LSD (1P-LSD) is a semi-synthetic lysergamide and structural analogue of LSD. The substance is enzymatically hydrolysed to LSD in the body and is therefore classified as a prodrug. Effects, dosage, and risk profile are largely identical to LSD. 1P-LSD has a half-life of approximately 10–12 hours and acts primarily as a partial agonist at the 5-HT2A receptor. Psychedelic effects include altered perception, visual hallucinations, and changes in cognition.

Effects & Pharmacology is partially translated. Some details are still being expanded.
1P-LSD (1-Propionyl-LSD) ist eine Prodrug für LSD. In vitro pharmakologisch nahezu inaktiv an 5-HT2A (Ki >1000 nM). In vivo spalten hepatische und intestinale Amidasen/Esterasen die 1-Propionyl-Gruppe, um LSD freizusetzen (Konversionshalbwertszeit ~1h). Die gesamte pharmakologische Aktivität stammt ausschließlich vom LSD-Metaboliten: 5-HT2A-Partialagonismus, 5-HT1A, 5-HT2C, D1/D2-Agonismus. Das Wirkprofil ist pharmakologisch identisch zu LSD, der Wirkungseintritt ist leicht verzögert durch die Prodrug-Konversion.

Avoid uncertain dosage claims and do not infer numbers when data is unclear.
Dose sensitivity varies greatly between individuals. Body weight, tolerance, route of administration, combinations, and pre-existing conditions significantly affect outcomes. These figures are not dosing recommendations — they describe reported ranges, not safe amounts.
