1cP-LSD Blotters (1-cyclopropionyl-lysergic acid diethylamide) is a psychedelic substance of the lysergamide class. It is a structural analog of LSD and a “prodrug” to LSD-25, meaning the body converts it into active LSD after ingestion.

The 100 mcg (microgram) blotter is the standard industry dose for this compound, designed to mimic the effects of a single “hit” of traditional street acid.

Hazard Statements:
1cP-LSD may cause respiratory irritation.
1cP-LSD may cause eye irritation.
Prevent discharge of Research chemicals into the environment.

Safety recommendations:
Keep research chemicals away from heat/sparks/open flames/hot surfaces. – Do not smoke
Store research chemicals in a tightly closed container and out of the reach of children!
IF 1cP-LSD CONTACT WITH THE EYES: Rinse carefully with water for several minutes; remove contact lenses, if possible; keep rinsing.
IF 1CP-LSD CONTACT WITH THE SKIN: Wash with soap and water.
Avoid breathing dust/fume/gas/mist/vapour/spray from 1p-LSD.
AFTER INHALATION OF 1cP-LSD: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
If the victim remains unwell, immediately call a POISON CENTER or doctor.

Chemical Profile: The “Prodrug” Mechanism

When you ingest 1cP-LSD, your body cleaves off the cyclopropionyl group, leaving the LSD molecule to interact with your serotonin receptors ($5-HT_{2A}$).

• Potency: Because 1cP-LSD has a slightly higher molecular weight than LSD-25, a 100 mcg blotter of 1cP is roughly equivalent to 80–85 mcg of pure LSD-25.

• Onset: Many users report a faster “come-up” compared to other analogs (like 1P-LSD), usually felt within 20 to 40 minutes.

• Duration: A typical experience lasts 8 to 12 hours, with the peak occurring between hours 3 and 5.
