Summary
PRO-LAD is a research chemical with very limited history of human use and minimal scientific documentation regarding its pharmacology, metabolism, and long-term toxicity. Unlike LSD, PRO-LAD has a propyl chain at R6 which may result in slower absorption and different onset characteristics. Users should employ rigorous harm reduction practices including reagent testing, accurate weighing with a microgram scale, and having a trusted sober trip sitter present.

Import into PsychonautWiki Journal
The PsychonautWiki Journal app includes PRO-LAD, but its built-in data can be thinner than ours. Importing this file adds a separate "PRO-LAD (Substance Search)" custom substance with our dose ranges, durations and tolerance, so you can log against whichever you prefer.
Ranges are harm-reduction guidance, not a prescription.
