Summary
1P-LSD is a research chemical and LSD analogue that first appeared in 2015. It acts as a prodrug for LSD, being rapidly metabolized into LSD in the body, with effects reported as virtually indistinguishable from LSD itself. Typically sold on blotter paper.
Perspectives
“To my discretion, there wasn't much to distinguish this from standard LSD, but perhaps further study is required. It nonetheless yielded an enjoyable and valuable experience.”
“I have experienced so many beautiful moments, and I believe learned much, through the use of this remarkable drug. Mild aftereffects are well worth enduring, given the perceived positives and benefits.”

Rapid withinβsession tachyphylaxis; reβdosing the same day yields little additional effect. Substantial decay by ~7 days; nearβbaseline at ~14 days for most, though individual variability exists.

Aggregated from 112 Erowid and 31 Bluelight experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect, something witnessed, or "did not happen" count too). Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.

No one really thinks about what happens after an acid trip, mild or otherwise. They seem only to focus on the trip and want/hope to see weird and wonderful things and with no real physical side effects. Sounds fun.
First things first: 100Β΅g taken at T:00, another 100Β΅g taken two hours later, on an empty stomach. As others have noted, this stuff is very slow on the come-up; 2 hours after my first dose I still felt no changes at all. Perhaps this is because I am a big guy physically, I dunno.
IΒve never written a trip report quite like this one before. The experience itself requires an insight into previous experiences, which I will try to give briefly in order to save space but this is inherently a long read.
1P-LSD (1-propionyl-lysergic acid diethyl amide) - where the P may well stand for 'placebo'. But really, who's to say for sure? Background: I am almost 40, and had plenty of experience with drugs such as: marijuana (copious amounts), LSD-25, Magic Mushrooms in my early 20s.
The Journey from a Bad 100ΞΌg Trip to a Great 200ΞΌg Trip A 1p-LSD Trip Summary 1. Preface The following is a summary of my experiences with LSD over a period of around two years. This summary comprises four trips.
This is a long story. It has two perspectives. (1) I woke up one morning, took a moderate dose of 1P-LSD, had a psychotic break that lasted three days, and have continuing psychological issues as a result of the experience.

It is hypothesized that 1P-LSD is a prodrug to LSD, meaning that they would be functionally indistinguishable in vivo. I had this in mind throughout the trip and of course I didn't perform this in a controlled manner with an identical setting, though forβ¦
