1S-LSD Stats & Data

Identity/testing: LSD reacts purple with Ehrlich and blue with Hofmann reagents, but 1‑acyl lysergamides can react weakly or only after delay as they de‑protect; use multiple reagents (Ehrlich + Hofmann) and consider TLC/LC‑MS at a drug‑checking service when available. Reagents degrade with heat/age; store cold per vendor guidance and replace when browned to avoid false negatives. Evidence: EUDA on LSD analysis; reagent best‑practice from Bluelight and r/ReagentTesting. Onset/redosing: Multiple user reports describe 1S‑LSD come‑ups of 90–180 min; redosing earlier risks sudden over‑intensification once deacylation yields LSD—wait at least 2–3 h before any redose. Evidence: Reddit threads collating delayed onset experiences. Potency: Users commonly estimate ≈70% LSD potency by mass for 1S‑LSD (molar‑mass argument); this is a heuristic, not a guarantee—batches vary and prodrug conversion may differ person‑to‑person. Start light if switching from LSD‑25. Evidence: community reports. Tolerance: LSD tolerance and cross‑tolerance with other serotonergic psychedelics build rapidly and fade over ~1–2 weeks; spacing trips reduces unpredictable potency/timing with prodrugs. Evidence: TripSit and Erowid on LSD tolerance. Storage: LSD degrades with heat/light/alkaline conditions; keep blotters/liquid air‑tight, dark, dry, and cool (amber glass, freezer for long‑term). Organosilicon N1‑substituent likely hydrolyzes in moisture; avoid humidity. Evidence: Erowid stability/references. Health/setting: Expect transient increases in heart rate, blood pressure, and temperature; ensure a calm setting, sitter if inexperienced, and avoid driving until well after effects resolve (often next day). Benzodiazepines are used clinically for severe agitation but should not be pre‑loaded or combined with alcohol. Evidence: StatPearls toxicology overview and human PK showing LSD onset/offset ranges. Drug checking prevalence: National programs (e.g., DIMS) find a non‑trivial fraction of ‘LSD’ blotters contain analogs or no LSD; testing reduces risk of misrepresentation. Evidence: EUDA/DIMS 2024 report.
