1S-LSD – The Latest LSD Prodrug

Chemical Collective has introduced an exciting new lysergamide derivative designed to succeed the beloved 1D-LSD (1T-LSD). This psychedelic compound is currently legal in Germany, allowing researchers there to fully explore its potential. 1S-LSD features a minor molecular modification to LSD-25, which exempts it from the Narcotics Act (BtMG), the New Psychoactive Substances Act (NpSG), and the Medicines Act (AMG).

Effects of 1S-LSD

We anticipate that 1S-LSD will yield effects akin to those of 1D-LSD (1T-LSD) and LSD-25. While it is still early to provide definitive data, as a lysergamide derivative with an ergoline structure, it is expected to exhibit properties similar to other well-known lysergamides.

Microdosing with 1S-LSD?

As an LSD prodrug, 1S-LSD is likely to function similarly to 1P-LSD, 1cP-LSD, and other compounds in microdosing scenarios.

Please be aware that 1S-LSD and other lysergamides do not distribute uniformly across blotter paper. Therefore, cutting blotters into smaller pieces for microdosing is not advisable. Instead, consider our 1S-LSD microdosing pellets for a more reliable option.

Is 1S-LSD Legal?

Currently, 1S-LSD is legal in Germany, France, Japan, and nearly every country worldwide that does not impose a blanket ban on psychoactive substances.
