http://psychonautwiki.org/wiki/1P-LSD1-propionyl-lysergic acid diethylamide (abbreviated as 1P-LSD or 1P-LAD) is a hallucinogenic psychedelic drug of the lysergamide family.
This substance has little to no history of human usage. It has not been reported upon within any formal scientific literature and is almost entirely unknown by both the academics and public. However, given its similarity to LSD and ALD-52, the structural similarity reliably suggests an extremely similar effect profile. Due to the lack of research regarding the substance, all discussion regarding the pharmacology of it is purely based on its structure and subjective effect similarities to other lysergamides.
Over the first few months of 2015, it came to be marketed as a legal alternative to LSZ, AL-LAD and LSD through online research chemical vendors which are currently selling the compound in the form of freely available blotter sheet tabs. It is usually marketed as a research chemical which means that it is sold legally but not meant for human consumption.
..ist ja schon ne Weile aufn Markt und wird auch in Kristallform angeboten, Preise imo völlig überteuert, aber dafür noch legal in DE.. zumindest kein btmg. Die Forenszene hab ich nicht mehr im Blick.. mal kurz durch die Threads gezappt.. scheint ja halbwegs an Acid ranzukommen. Die Kristalle wären jetzt mal interessant um in Richtung high-dose (z.b. nasal zu experimentieren)

hatte es von Euch schon jemand unter der Zunge?
