809990

From Syracuse, New York on March 13, 2025

Assumed to be fentanyl

This is a messy brew of 6 major substances:

  • medetomidine
  • tetracaine
  • 4-ANPP
  • heroin
  • fentanyl
  • bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate

Fentanyl is potent and the amount changes by batch. If you weren't expecting it, consider getting test strips online or from a harm reduction program. Carry naloxone (Narcan) to reverse overdoses. Don't use alone so someone can help if you go out.

There are a lot of different substances in this sample. We don't know the harms that some of these can cause. Be careful and be prepared for unexpected reactions.
