N-isopropyl butylone is a synthetic cathinones with very limited information available on its dosing and effects.
It is almost certain this substance will be misrepresented as MDMA .
Never assume that the drug you have is what it was sold as.
Misrepresentation can occur anywhere along the supply chain.
The effects of N-isopropyl butylone are currently unknown, may be similar to eutylone and N-ethylpentylone, both of which have caused considerable harm.
If you or someone you know takes a substance thought to be MDMA and starts to experience unusual effects, call emergency help.
Be honest about your drug use. You won’t get in trouble, and it could save you or your friends’ life.

N-Isopropyl butylone is one of many structural isomers with the chemical formula C14H19NO3
(e.g., N-ethyl pentylone, N,N-dimethylpentylone, N-propyl butylone). N-Isopropyl butylone was first identified in August 2024
