Summary
4-HO-EPT is a novel research chemical with very little history of human use before 2016 and almost no scientific research on its pharmacology, metabolism, or toxicity. Unlike more visual tryptamines, it primarily enhances colors with a neon quality rather than producing strong visual distortions. Users report a strong euphoric body high sometimes compared to opiates, with a generally light and positive mindset. Accurate weighing with a precise milligram scale is essential. Individuals with personal or family history of psychotic disorders should avoid use.
