Overview

The drug is reportedly rare and there is little known about it. It is an extremely potent research chemical analogue of fentanyl. This powerful opioid is generally only dispensed as a nasal spray. It is strongly recommended to handle with extreme caution and to avoid mixing it with other depressants.
