Responsible Research with 1P-LSD

Always practice responsible research. You should read and educate yourself before undertaking research with any chemical. The Psychonaut Wiki has some very helpful resources and information on 1P-LSD, so does Set and Setting. Never conduct research with a chemical without learning about it first.

WARNING This product is not for human or veterinary use.

What is 1P-LSD?

1P-LSD is a psychedelic substance of the lysergamide class and it is thought to be a prodrug of LSD-25. 

What are 1P-LSD Micro Blotters?

1P-LSD 20mcg “micro blotters” are blotters that contain 1/5 the amount of a “regular” 100mcg blotter of 1P-LSD. These blotters can be easily divided into pieces using scissors or a sharp knife, so the researcher can choose to conduct their experiments with smaller amounts of 1P-LSD.

Can 1P-LSD be used for microdosing?

1P-LSD is very commonly used in place of LSD-25 for microdosing. Generally, users report that the effects are virtually indistinguishable from one another.

Some of the most commonly reported effects are:

  • Stimulation
  • Physical euphoria
  • Tactile enhancement
  • Stamina enhancement
  • Appetite suppression
  • Bodily control enhancement

Potential Side Effects

  • Difficulty urinating
  • Excessive yawning
  • Nausea
  • Muscle contractions
  • Muscle spasms
  • Pupil dilation

1 review for Micro 1P-LSD 20mcg Blotters

  1. Vakaloura

    Me llama mucho la atención que haya muchas reseñas (positivas) para las micro de 20 Mg de 1cp y ninguna para 1p LSD. Yo he investigado ambas y considero el 1p LSD para ese fin ( microdosificar) más adecuado. Esto, como casi todo, es muy subjetivo y dependerá de lo que cada cual busque con dosis micro . Personalmente cuando decido microdosificar cada 3 días una lisergamida, mi primera opción siempre será 1p-lsd
